    THE CLEAVER TANK CAR HEATER
    FOREWORD
    The CLEAVER Tank Car Heater is an oil-fired, high pressure steam boiler of riveted construction, produced under strict supervision and code regulations for boilers and pressure vessels.
    In contrast to other types of mechanical equipment such as engines and motors, which generally stop completely when neglected or otherwise abused, a steam boiler becomes a definite menace and, furthermore, may be damaged beyond the ability of readily available repair facilities if not properly operated and cared for.
    By following a few simple rules, each operator may assure himself that the service he and the machine are assigned will be performed and that the next individual to run it will not be handicapped because of his negligence. All points of operation are fully covered in this book> but if the following suggestions are remembered, the best possible performance will be assured and the machine’s life definitely prolonged:
    1.	Keep a safe water level in the boiler. The most desirable height is about three (3) inches of water in the gauge glass. Should it fall to one (1) inch, determine the cause of water loss and make immediate corrections. Shut tfie machine down immediately if no water is visible in the water gauge glass.
    2.	Oil and lubricate at prescribed intervals.
    3.	Use clean water and frequently blow down boiler, water column and water gauge glass.
    4.	Keep all steam and water connections tight to avoid loss of water and waste of fuel.
    5.	Report operating irregularities which you are not able to correct to proper authorities.
    This instruction book applies to the operation of both 2- and 3-car models of CLEAVER Tank Car Heaters as the machines are identical in construction, with the exception that the 3-car unit boiler is slightly larger and has a greater steaming capacity.
    The terms "2-car" and ’’3-car'’ refer to the steam generating capacity of the units and express the ability of the machine to maintain steam pressure in the coil systems of two and three standard 10,000 gallon railroad tank cars simultaneously.
    The function of a steam boiler is to convert and transfer the chemical energy in the fuel which is burned to heat energy in the steam and thus render it available for use in heating systems or for conversion into mechanical energy by an engine. The CLEAVER Heater is designed for heating purposes, chiefly in connection with bituminous materials suchwas road oils and asphalts. Heat leaves the boiler in the form of steam and is given up as the asphalt or road oil is heated, and, as the heat is exchanged, the steam is condensed to hot water and returned to the boiler by the condensate pump.
    THE CLEAVER TANK CAR HEATER
    Page 3
    By returning all condensate to the boiler, water is used over and over again, minimizing the tendency to scale the water side of the boiler and practically eliminating the water supply problem. In cases where live steam is used to atomize fuel oil for aggregate dryer burners, it is, of course, impossible to recover the condensate and the boiler water level must be restored from time to time, either by using the injector or by drawing water from the tank on the unit by means of the turbine pump.
    Performance of a steam boiler is Judged by its efficiency, which is the proportion of the heat units the fuel consumed actually converted to steam leaving the boiler.
    As the formation of soot or carbon on the fire side and scale on the water side of a boiler act as insulation, it is therefore essential that both surfaces be kept as clean as possible. The CLEAVER Tank Car Heater is provided with a fuel oil burner which intimately mixes air and oil, providing complete combustion, assuring the minimum deposit of soot on the tubes. This feature, together with the rapid passage of combustion gas through the combustion chamber and three successive passes of smaller tubes eliminates the necessity of cleaning the tubes from the fire side before 5,000 hours of operation.
    GENERAL DESCRIPTION OF CLEAVER TANK CAR HEATER
    The CLEAVER Tank Car Heater is a self-contained steam generating plant constructed for operation at pressures up to 125 pounds per square inch, fired by an oil burner and equipped with built-in fuel and water tanks. Water is fed to the boiler by two methods, a standard injector and a power driven pump which may draw water either from the reserve tank or condensate from the coils in the tanks being heated.
    Of fire tube construction, the boiler is equipped with four complete passes of flue gas travel, the first pass being the large center tube or combustion chamber, the second pass of two groups of tubes at either side of the fire tube and the third and fourth passes below. The vent pipe or stack is a part of the outer head at the firing end of the boiler. (See cut-away view on page 4). The oil burner is of the pressure atomizing type with three fuel oil atomizing nozzles. Two 5-gallon and one 4-gallon nozzles are used on the three-car heater, giving a total burning rate of fourteen gallons per hour. The two-car heater is equipped with two 4-gallon nozzles and one 3-gallon nozzle, or a total of eleven gallons per hour. By manually operating the valves to the individual fuel oil nozzles and adjusting the air supply to the burner, the firing rate may be varied to suit the steam requirement.
    All air for combustion of the fuel oil is supplied by the engine driven blower which is provided with a damper at the blower outlet to adjust the volume of air in correct proportion to the fuel burned.
    The power plant is a single cylinder air—cooled gasoline motor,directly connected to the condensate return pump. Power transmission to the blower and to the fuel oil pump is by means of V belts. Boiler proper is insulated with 1-1/2" Banroc blanket protected by sheet metal lagging. Space below the boiler at the towing end is utilized as a tool compartment, access to which is by means of a top-hinged door at the right side of the towing end of the unit.

    Unlock hood over power plant and raise to resting position as shown in Figure 1, engaging pin safety lockonrest at top of boiler to prevent hood from being blown down by the wind.
    From the inside, open left door of operating housing. Unlock tool compartment door, right front, at bottom of unit chassis.
    Locate the heater as near the work as possible, consistent with free access to other equipment being used on the project. Set unit as nearly level as possible by digging in either or both wheels or the front leg post. The screw jack provided with the machine may be used under the circular power plant frame end to relieve the weight from the tires during operating period.
    The following should be provided in sufficient quantity to assure continued operation for the period stipulated:-
    1.	Fresh Water
    2.	Fuel Oil
    3.	Gasoline
    4.	Lubricating Oil
    5.	Ball Bearing Grease
    Water
    If the heating operation allows the return of all condensate to the boiler, fifty gallons of fresh water for boiler make-up should suffice for each day's operations. However, if only part of the condensate is recovered, the fresh water requirements will be greater. Make-up water for the boiler may be withdrawn from the built-in water tank on the unit by either the pump or the injector. The valve and piping arrangement also permits drawing water from an open bucket or barrel by the injector.
    If only*salt water is available, proceed according to instructions on Page 22.
    Fuel Oil
    The CLEAVER Tank Car Heater is designed for use with No. 3 U. S. Standard fuel oil, having a viscosity not exceeding 50 seconds Saybolt Universal at 100° F. Lighter fuels such as No. 1 and No. 2 may be used very satisfactorily. Practically all clear or straw-colored so-called tractor or Diesel fuels are suitable, but black, heavy viscous oils should be avoided as the pressure atomizing nozzle cannot atomize them for proper combustion.

    Should no other fuel oil be available, kerosene or coal oil may be used but lubricant must be added to lubricate the gear-type fuel oil pump. Add one half pint #30 lubricating oil to each 5 gallons kerosene.
    Gasoline may be used for fuel oil as a last resort, but the operator is cautioned to exercise every care in handling to prevent accidents. Add one quart lubricating oil per 5 gallons gasoline fuel used.
    Steam Outlet and Return Connections
    The main steam outlet of the CLEAVER Tank Car Heater is located at the top center of the boiler proper, between the water column and injector steam connections (See Figure 1). The 1—1/2" pipe fitting at the boiler is reduced by piping furnished with the unit to one inch at the upper elbow and a 1" globe valve provided as a shut off for all steam leaving the boiler. A 1 union is provided at the valve, one half of which should be attached to the hose carrying steam to the process. Complete this hose connection, making the run as short as possible. See Figure 3.
    If the heating is by means of steam coils, the live steam line should be connected to the inlet connection, so marked on the device, and a hose connection provided from the outlet to carry the steam condensate back to the condensate pump, which in turn forces it into the boiler as feed water. The return line connection is attached to the valve leading to the condensate pump straiper as shown in Figure 4.
    If steam is being used in coil heating and also in the steam atomizer of an aggregate dryer, a branch should be provided in the main steam line to serve that device, using pipe or hose of the size recommended. In all cases where steam is being used for more than one appliance, a stop valve should be installed in the steam inlet line to each.

    OPERATING LEVEL
    Any one of several methods may be • used to fill the boiler with water for a cold start, the simplest being to remove the tee at the main steam outlet at the top of the boiler and fill either with pressure hose or by pouring with hand bucket.
    Make sure that the boiler blow-down or drain valve Is closed with Its operating handle horizontal as shown in Figure 7.
    The boiler water gauge glass Installed on the water column (See Figure 6) should be observed at all times by the operator to determine the boiler water level. Make sure that the top and bottom cocks are fully open by turning the wooden hand wheels to the left. Only with these cocks In the open position can the boiler water assume the true water level In the glass. When starting cold, fill the boiler to the point where two inches of water appear In the glass. (Water expands when heated and as steam pressure Is built up, the level will rise to about four inches in the glass.)
    (Select one of the three methods described below, according to conditions.)
    Through Cold Injector
    If water pressure service is available, a hose with 3/4" fittings may be attached to the injector inlet (See Figure 8) and a 3/4" iron pipe plug, screwed into the injector overflow.
    Open Valve 3 (discharge to boiler), Valve 1 (steam to injector) and Valve 5 in the water supply line. Close Valves 4 and 6. Start water flow, venting air displaced by water by opening one or more water column tri-cocks.
    When water has reached the recommended level of two inches in the glass, shut off supply, remove plug from injector and close Valves 1, 3, 4, 5 and 6. Water pressure service to the injector may be used in this way for all water feeding requirements during operation as explained under "Operating Inj ector".
    FIG.6

    Through Main Steam Outlet
    If no water pressure is available, disconnect the tee from the 1-1/2" nipple between it and the boiler and fill with buckets, using a funnel if available, until about 2" water appears in the glass. Replace tee on main steam outlet and attach hose to point of steam use. Close main steam outlet valve.
    Through Water Pump (See Figure 9)
    Fill water supply tank with water and make provisions to add sufficient water to its 30 gallons to make up the 90 gallons the boiler will require for start, leaving a full tank for operations. Follow instructions as to engine and fuel oil preparations. The two-car heater water tank holds ~ 30 gallons and the boiler requires 96 gallons. Close main fuel oil Valve #9, Figure 5.
    Open Valve 1, allowing water to be urawn from the water tank to the pump suction or inlet.
    Close Valve 2, cutting off the return condensate line to prevent air being drawn into the pump.
    Open Valve 3, allowing water to be discharged from the pump to the boiler.
    Fill priming cup (4) with water and open Valve 5.
    Start engine.
    Keep priming cup filled with water to run to pump until about a half pail of water has been drawn into pump and close Valve 5.

    Water should then be picked up by the pump and drawn from the tank and forced into the boiler. To check water pump flow at start, open blow . down valve (Figure 7) and close when steady flow of water appears.
    When two inches of water appears in glass, close Valve 1 to stop water feeding.

    At this point, the operator should make certain that the engine will start and run properly before attempting to fire the burner.
    Start engine by releasing compression lock as shown in Figure 11.
    Speed should be between 2150 and 2200 R.P.M.

    Check belt drives.
    While engine is warming up, the fuel oil pump (No. 12, Figure 5) should withdraw fuel oil from the tank, building up a pressure of 100 pounds on the fuel oil pressure gauge (No. 11, Figure 5). If the pressure is above or below 100 pounds, adjust fuel oil-pressure relief valve (No. 10) to 100 pounds, the recommended pressure, as described on Page 17.
    Stop engine.
    Open main fuel oil valve to burner (No. 9, Figure 5) and close both individual valves to the burner (Nos. 1 and 2). This allows start on but one nozzle.
    Shut off all air to burner by turning handle on butterfly air damper at blower outlet to vertical position (No. 7, figure 5).
    FIGURE I I
    Page 14
    FIRING THE BOILER
    Open lighter port hole located at right of burner air tube where entering boiler. See Figures 10 and 11. Immerse wick end of torch in gasoline and Ignite. Insert flaming end of torch into lighter port hole only far enough for torch to rest at bottom of combustion chamber, about 15 inches.
    Start engine. Fuel oil pressure to nozzles should immediately reach 100 pounds and the oil fire will ignite. Immediately remove torch and open air damper only sufficiently to eliminate emission of smoke at stack. Extinguish torch flame.
    To fire at full capacity, turn on second nozzle by fully opening the individual fuel oil valve below burner tube. See Nos. 1 and 2, Figure 5. First opening turn of valve should be very slow to prevent snuffing out of fire. Again open air damper only far enough to eliminate smoke. Open remaining valve to fire third nozzle and again adjust air to burn without smoke.
    See that cock in pipe to steam gauge is open.
    Maintaining Steam Pressure
    The first indication of steam pressure will be the emission of steam from one of the water column tri-cocks which was opened to relieve the pressure created as the water replaced the air in filling boiler. Close all water column tri-cocks, the "steam to Injector" valve and the main steam outlet valve.
    The pop safety valve on the CLEAVER Heater is set to blow off at 125# gauge. Highest recommended operating pressure is about 120#. Pressure closer to the blow off point of 125# results in unnecessary blow offs, wasting water and fuel.
    Determine pressure at which steam is used. When boiler pressure reaches that point, gradually open main steam valve, cracking the valve first so that only a trickle of steam is emitted as evidenced by the hiss of steam, through the small valve opening. Open further to the fully open position at the rate of about one valve turn every 10 seconds.
    With the steam consuming equipment in operation, the boiler operator’s duties involve:
    1.	Keeping constant steam pressure.
    2.	Feeding water.
    3.	Adding fuel oil and gasoline.
    The steam generating capacity of the CLEAVER 2-Car Heater is approximately 34 horse power (3-Car Heater, 42 JH.P.). Steam pressure will gradually rise so long as the steam generating rate of the boiler exceeds the steam consumption rate. Should the steam consumption exceed the capacity of the boiler, the pressure will gradually fall.
    Obviously, then, the operator should fire the fuel oil burner at a rate which will keep the steam pressure constant at the desired point.

    If firing at full capacity with all three nozzles on, turnoff Valve 1, Figure 5, or Valve 2, and close air damper on blower outlet to point where burner smokes, then open damper until smoke disappears. If firing with only two nozzles, turn off the remaining open valve.
    If Steam Pressure Falls
    Burn more oil by turning on the valve to an additional fuel oil nozzle. Increase air to fire by opening air damper to eliminate smoke.
    If pressure falls with all three nozzles firing, and steam consuming opllance is hot, steam is being used faster than it can be generated.
    (Pressure may fall slightly when feeding cold water to boiler, but will recover gradually between water feeding cycles.)
    F ir ing Rule
    After each fuel oil burning rate change, adjust air delivery at blower outlet. As oil is Increased, supply more air; as oil is decreased, cut down air. Operate at all times with only sufficient air to eliminate smoke, at which point flame is most efficient.
    Blow Down
    Blow down boiler at blow down valve (Figure 7) by opening valve to allow vigorous passage of steam and water for at least five seconds and, with a head of steam, at least once each 8 hours.
    Blow down water column and water column gauge glass at least once each 8 hours.
    Keep water gauge glass clean.
    NEVER FIRE BOILER WHEN NO WATER APPEARS iN THE WATER GAUGE GLASS — OTHERWISE YOU WILL INVITE SERIOUS DAMAGE!

    FEEDING WATER
    The condensate return system on the CLEAVER Heater Is of the "trapless" or "closed" type. Do not install traps of any type between the discharge end of heating coils and the feed water pump on the heater. No valves in addition to that on the condensate inlet (See Figure 9) at the water pump on the machine are required.
    Where the operation uses steam for aggregate dryer burner atomization and in coil heating, the condensate from the coils is returned to the boiler, and water must be added either by the injector method or by pumping from the water tank to replace that lost through steam entering the dryer.
    Condensate Return Insufficient to Maintain Boiler Water Level
    Draw water from tank by opening Valve 1, Figure 9. If level in boiler does not rise, close condensate return valve No. 2, Figure 8. Prime pump as described on Page 10 if pump does not pick up water.
    Operating Injector
    The injector is a steam operated device which forces water from an open container, or a water pressure line into the boiler. It will not operate properly on boiler pressure•under about 35 pounds.
    Open fully Valve 3, Figure 8, in the discharge line from the injector to the boiler.
    Open fully Valve 5 in the supply pipe either from water pressure line or open container. If drawing water from open container, see that inlet strainer is fully submerged in water. Close Valves 4 and 6.
    Quickly open steam Valve 1 and injector should Immediately pick up water, forcing it into the boiler. If water spills out overflow, gradually close supply water Valve 5 until overflow stops and injector picks up water.
    Injector will not operate with hot make-up water or while device itself is hot. If, after several attempts to operate, water spills out overflow, close steam Valve No. 1 and dash cold water over it to cool. When cooled, proceed with new start.
    To Fill Water Tank With Injector (See Figure 8)
    1.	Close Valve 3 (injector discharge to boiler)
    2.	Close.Valve 4 (tank suction to Injector)
    3.	Open fully Valve 6 (injector discharge)
    4.	Open Valve 5 (water supply valve)
    5.	Open fully steam-to-injector Valve No. 1.
    FEEDING WATER
    Page 17
    Water will be picked up from open container and fed to tank. Remove water tank fill cap. When filled to neck, close steam valve and replace the tank cap.
    OPERATING IRREGULARITIES AND THEIR CORRECTION
    Low Steaming Capacity
    No boiler can keep up steam pressure if the total steam load connected to it is greater than its output capacity when fired at its maximum rate.
    Steam leaks, however small, should be corrected whenever detected and all recoverable hot condensate returned to the boiler by the method provided.
    See that engine is up to speed. (2150-2200 R.P.M.)
    Make sure that fuel oil is turned on to all three nozzles (Valves 1 and 2, Figure 5).
    Fuel oil pressure must not be less than 100 pounds.
    To Adjust Fuel Oil Pressure
    Remove hexagon cap at top of fuel oil pressure relief valve (See Figure 12). With engine running, use screwdriver to Increase tension on internal spring to increase oil pressure, watching fuel oil pressure gauge while making adjustment.
    To decrease oil pressure, turn screw out. To increase pressure, turn screw in.
    When fuel oil pressure has been adjusted to 100 pounds, replace cap snugly against gasket, making it oil-tight.
    FIG.12
    Page 18
    FUEL OIL FILTER
    Replacing Fuel Oil Filter Element
    The purpose of the fuel oil filter (See Figure 13) Is to remove all foreign matter from the fuel oil to keep abrasives out of the pump, preventing excessive wear. The filter also removes small particles which may lodge in the small passages of the fuel oil atomizing nozzles.
    AH fuel oil handled by the pump on the unit passes through the filter. When the outer surfaces of the cotton filter element become plugged, oil will not pass through it and the fuel oil pressure gauge will fluctuate between 0 and 100 pounds pressure, extinguishing the oil fire due to the lack of the proper quantity of oil at the proper pressure of 100 pounds.
    1.	Disconnect copper tubing leading from the fuel oil tank to the filter body, by detaching the copper tubing fitting at filter inlet.
    2.	Disconnect 3/8" union at top of fuel oil pump which attaches filter housing to pump and remove complete filter unit from machine.
    3.	Remove 4 cap screws attaching filter cap to body and withdraw old filter element from housing.
    4.	Thoroughly clean housing inside.
    5.	Insert new filter Into housing.
    6.	Assemble filter body and cap with gasket between, Installing the four cap screws and lock washers.
    7.	Attach assembly to fuel oil pump by making up 3/8" union tightly.
    8.	Attach copper tubing to suction line by connecting copper tubing connector.

    Clean Fuel Oil Nozzles
    Fuel oil pressure gauge may show 100 pounds, but plugged or partially plugged atomizing nozzle internals may greatly reduce fuel oil delivered to the fire, thus decreasing fuel oil capacity. Shut down machine and dismantle burner as follows:
    Disconnect fuel oil line to burner at copper tubing connector, No. 1, Figure 14.
    FIGURE 14
    Remove 8 brass screws attaching brass air tube collar to front and rear connecting tubes. Slide collar A toward the blower on brass tube B. Withdraw tube B with collar A from air cone adapter C and withdraw burner assembly by pulling it away from the boiler until free.

    OIL BURNER
    Remove all three nozzle tips from bodies, see Figure 15. Remove nozzle strainer screen from nozzle tip with the fingers, and with a screwdriver, the remaining internal part of the nozzle tip proper. Clean all internal surfaces of the nozzle tip and the slotted ports of the internal assembly, using a wood splinter so that the small oil grooves will not be damaged, particularly the small hole in the nozzle tip proper. Clean nozzle strainer screen carefully, removing all foreign matter to allow free passage of fuel oil through nozzle. Replace nozzle internal core, using a screwdriver to set it tightly, but not excessively so.

    IT IS ESSENTIAL THAT THE INTERNAL CORE BE TIGHTLY SEATED IN THE NOZZLE TIP FOR PROPER ATOMIZATION OF THE FUEL OIL.
    Replace the strainer screen, screwing it into the nozzle assembly only finger-tight. Replace nozzle into brass nozzle body, using open end wrenches as when removed, seating tips tightly to prevent fuel oil leakage.
    Installing Oil Burner
    Insert oil burner internal assembly into air tube D attached to the boiler head with fuel oil tubing inlet connection at bottom (See Figure 14). See that collar A is outside of tube B and insert tube B into air cone adapter C. Slide collar A toward and slightly over tube D, lining up holes and installing the four screws attaching collar A to air tube D. Line up holes and attach tube B to collar A with the four screws.
    Connect fuel oil tubing to burner inlet at the bottom of the burner assembly.
    Boiler Tubes
    After about 5,000 hours of operation the fire side of the boiler tubes may be sufficiently coated with soot and carbon to justify cleaning. Clean tubes as prescribed in Maintenance Manual, Page 1.

    The Water Pump
    ALIGNMENT. The flexible coupling between pump and engine should be carefully aligned. Inaccurate alignment results in rapid wear of the coupling bushings, heating of the bearings, causes noisy operation and may materially shorten the life of the pump.
    STUFFING BOXES. Packing glands should be drawn up while pump is in operation - just enough to prevent excessive leakage. A slight leakage of a few drops per minute is recommended as this reduces friction losses and avoids scoring of the shaft. Once a shaft becomes scored, packing box difficulties can be expected. Use only special metallic packing furnished with pump. All old packing should be removed and new packing installed occasionally.
    When priming trouble is being experienced, the packing glands may b>. too loose, permitting air to be drawn into the pump. Draw up on glands, but not too tightly.
    No water delivered or not pumping full capacity.
    (a)	Pump not primed
    (b)	Air leaks in return line
    (c)	Suction lift too high
    (d)	Return line or strainer clogged
    (e)	Mechanical defects
    (f)	Air leaks through stuffing boxes
    Pump takes too much power.
    (a)	Packing too tight
    (b)	Impeller out of adjustment and rubs casing. Check pump - should turn freely by hand.
    Keep rust or dirt out of the pump by cleaning the condensate strainer (See No. 3, Figure 5) as often as experience shows necessary.
    Be sure that all piping, valve stems, and strainer cover on suction side of turbine are tight, as air leaks will positively prevent the turbine from pumping water.
    When there is danger of freezing, open cock under pump and drain.
    Keep grease cups filled.
    Do not throttle valve in discharge line to reduce capacity.
    If pump is to be Idle for a long period, it should be taken apart, cleaned and oiled as described in Maintenance Section.
    Page 22
    THE BLOWER
    Blower Speed
    All air for combustion is provided by the blower and during normal running operation the stack should be clear of smoke. If blower smokes with three nozzles firing and with air damper in blower outlet open, increase engine speed only sufficiently to clear smoke.
    Engine should not be run faster than required to drive blower to produce sufficient air to assure smokeless operation under full capacity with butterfly damper in blower wide open.
    , I
    Boiler Scale
    Scale on the water side of the boiler tubes may eventually decrease the proper steam capacity of the unit. Make up water should be treated for scale removal as described on Page 17, Maintenance Manual.
    COLD WEATHER OPERATION
    When operating at temperatures below freezing, precautions should be taken to see that piped water supply is kept open to prevent interference to boiler water feed.
    Injector should be operated frequently to prevent freezing as boiler upper surface is insulated and radiated heat may be insufficient to prevent freezing.
    During cold weather shut-down periods, the machine should be drained completely as instructed in the first paragraph under "Storage Procedure" following.
    EMERGENCY OPERATION WITH SALT WATER
    The CLEAVER Tank Car Heater should not be operated with salt water unless absolutely necessary as the salt will be deposited in scale form on the water side of the tubes and materially reduce heating capacity and shorten the life of the boiler.
    To operate with salt water, fill boiler as directed under "Filling With Water" and proceed with operations as with fresh water, recovering and returning all condensate to the boiler that it is possible to save, as condensate is pure distilled water.
    As soon as fresh water is available, stop machine, drain and refill with fresh water.

    Assemble unions in the 1" water suction pipe leading to the water pump and in the 3/4" water pump discharge line.
    CLEANING WATER SIDE OF BOILER
    CLEAVER Tank Car Heaters, because of their portable use, are subjected to innumerable types of chemical combinations in feed water, and consequently no hard and fast rule may be applied to the treatment of feed water to prevent the formation of scale on the tubes or the opposite case, which results in the pitting of the tubes. The Important maintenance requirement is to remove the scale and flush out the boiler as often as required as determined by inspection after removal of one or more of the four hand hole plates.
    Consult the nearest available authority on boiler water scale removal and proceed according to his recommendation after he has observed the condition.
    Hand Hole Plates
    Two hand holes are located in the sides of the top half of the boiler shell, one toward the right (towing end), and the other toward the left (firing end) front. The remaining two hand holes are located on the left bottom side of the boiler, front and rear. Access to the two lower hand holes may be gained by removing the front and rear steel panels at the left lower side of the housing.
    When removing a hand hole plate be careful not to drop it Inside the boiler. With a pair of pliers, hold the hand hole bolt and remove the outer nut. Remove the yoke, then release the plate, and gasket with a hammer if stuck to the boiler shell inside surface. Grasp the bolt and remove the plate which is attached to the bolt head.
    When replacing gaskets, apply a coat of graphite and oil to both surfaces.
    Replacing Fusible PIug
    The fusible plug which melts on a low-water condition and warns the operator by an emission of steam from the stack, is located on the rear flue sheet (towing end) just above the fire tube.
    To replace, remove rear head as instructed on Page 1. For location of fusible plug, see Figure 16M.

    Page 19
    Follow operations in order given below and refer to cross section drawing on Page 18 for references.
    Read instructions entirely before starting to disassemble.
    1.	Remove	cover plate cap screws No.	19A.
    2.	Loosen	adjusting nut set screws No. 29-
    3.	Remove	adjusting nut No. 25.
    4.	Remove	jam nut No. 24. (Requires	socket type	wrench)
    5.	Loosen	packing gland eyebolts No.	18A and swing	clear of gland
    No. 17A.
    6.	Cover plate No. 22 can now be removed - should it stick, tap lightly around flanged edge to loosen or drive flat edged tool (screw driver or chisel) between flanges of cover plate •	and pump shell at several points around shell. (Be careful
    or you will break flanges).
    7.	Loosen set screw No. 42 and remove lock collar #39.
    8.	Remove adjusting nut #5.
    9.	Remove Woodruff key #3 so that shaft will be allowed to slip through bearing.
    10.	Withdraw shaft and impeller from pump. As shaft is removed, gland #17 and slinger #16 will also come off.
    11.	To remove impeller from shaft loosen set screw #21.
    12.	To remove cover #15, remove cap screws #19. Ball bearings may be removed from bearing housings by pushing them outward from stuffing box side of bearing housing.
    REASSEMBLY OF WATER PUMP
    Although both covers which make up the bearing housings and stuffing boxes appear similar, they are not interchangeable. Determine proper cover by matching intake and discharge ports of each cover with those in the shell.
    1.	Install impeller on shaft with Woodruff key between. Face hub of impeller toward threaded end of shaft. Do not seat set screw.
    2.	Insert shaft and impeller into right hand cover (#22).
    3.	Remove grease cup over bearing 23 and install bearing from outer end. Sighting through grease passage hose and while bearing is snug against shoulder of shaft, line up pump side of bearing with center of grease passage hole.
    Page 20
    THE FEED WATER PUMP
    4.	Holding shaft in this position, locate impeller on shaft so that its face, toward cover 22, barely clears without rubbing. Carefully remove the shaft and tightly set screw 21 on impeller hub, making sure that Woodruff Key #10 is in place.
    5.	With all packing (11) removed, insert shaft through cover (22) with packing gland (17A) and slinger (16) in place. Pass shaft through adjusting nut (7A), insert bearing and install jam nut (24) with socket wrench.
    6.	Install adjusting nut (25) loosely.
    7.	Install cap screws (19A).
    8.	Install cover (15) with packing gland (17) and slinger (16) and adjusting nut (7) in place.
    9.	Install ball bearing (14), adjusting nut #5 and bearing collar #39, rotating until it slips into the adjusting nut. Turn on shaft until it binds, then seat set screw #42.
    INSTRUCTIONS FOR ADJUSTING IMPELLER CLEARANCE (After Assembly)
    1.	Screw in adjusting nut No. 25 partially. Make sure both adjusting nuts Nos. 25 and 7A are loose before starting the adjustment. Leave locknut #36 and adjusting nut No. 7 slightly loose.
    2.	Tighten adjusting nut No. 25 sufficiently that shaft will not turn (to try this take hold of coupling and try to rotate.) The impeller is now rubbing against cover plate on coupling side of pump.
    3.	Loosen adjusting nut No. 25 just a fraction of turn or until you can rotate shaft freely. Now tighten up on adjusting nut No. 7A and try to rotate again. If pump turns over freely with no indication of Impeller rubbing, the pump is properly adjusted. If rubbing still occurs, you can work the two adjusting nuts "back and forth" until pump does rotate freely. Do not tighten up on adjusting nuts too much, just bring up firmly by very light taps on hammer. After proper adjustment has been secured, then lock adjusting nuts by tightening up the adjusting nut set screws No. 29, located in the bearing arms.
    4.	It is recommended that impeller adjustment be made with packing removed from pump.
    IMPORTANT
    When pumping hot liquids, should pump fail to rotate freely due to excessive expansion of casing and shaft, loosen adjusting nuts No. 25 and No. 7A. Now readjust as per preceding Instructions at operating temperature.
    THE FUEL OIL RELIEF VALVE

    If fuel oil pressure shows 100 pounds and no oil is delivered at the burner, the internal parts of the relief valve may be stuck. Tap the device with a hammer handle (not the head) to dislodge foreign matter that may be causing it to stick.
    Should this treatment fail, dismantle and clean the device as follows:
    1.	Stop engine.
    2.	Disconnect union tee attaching valve to fuel oil pump.
    3.	Detach copper tubing below valve at bottom of relief valve.
    4.	Detach copper tubing connector in line leading to fuel oil tank.
    5.	Remove cap, #3, Figure 24M.
    6.	Remove adjusting screw, #4.
    7.	Hold device securely (do not compress vise jaws around it) and remove bonnet, #2.
    8.	Withdraw spring guide, #7, spring, #10, and piston, #6.
    9.	Dismantle bottom assembly by removing seat, #22.
    Clean all parts carefully and reassemble, using Figure 24M as a guide.

    THE FUEL OIL PUMP
    Pumping Principle
    The pumping principle is the same for all Tuthill Model L pumps and is known as the "internal gear" principle. See accompanying figure. Power is applied to the rotor and transmitted to the idler gear with which it meshes. The space between the outside diameter of the idler and the inside diameter of the rotor is sealed by a crescent-shaped projection. As the teeth come out of mesh, there is an increase in volume which creates a partial vacuum. Liquid rushes into the pump to fill this vacuum and stays in the spaces between the teeth both of the idler and rotor until the teeth mesh. The liquid is then forced from these spaces and out of the pump.

    THE TUTHILL FUEL OIL PUMP

    If for any reason this pump requires service of any nature it should, if at all possible, be returned to the factory for correction. However, in extreme cases when it is absolutely necessary to take the pump apart in the field, the following procedure must be strictly adhered to.
    To remove the seal assembly, 30L13, first place the pump in a vise so that one jaw grips across the two ports. Do not squeeze too tightly as this will deform the casting.
    Remove cap 0L68, using a spanner wrench if one is available.
    Then, holding shaft from rotating by placing a wrench across the flat on the shaft, loosen nut 0141 in the vise - being careful not to deform the nut by applying too much pressure - and pull 0F9 assembly off the shaft.
    With a pair of small tweezers, remove pin key 0L69.
    •
    At this point care should be exercised to see if there is a small burr raised on the shaft where the pin key enters the shaft. If so, a small file should be used to remove this burr.
    Then place the pump again in the vise as before and remove housing plug assembly, 30L11.
    When the seal assembly is removed from the pump, both the seal parts and the seal assembly must be kept absolutely clean and free from dirt or any other foreign matter.
    The rotor and idler may then be removed from the pump by removing the screws securing the front cover.
    When the front cover is again assembled onto the pump, extreme care should be taken to see that the gasket has been kept in good condition. Both sides of the gasket should be covered with a coating of cup grease or very thin shellac and particular attention should be given to see that the screws are tightened evenly. Position the cover with the crescent at the bottom, opposite the ports and the locating notch in the rim of the cover, at the top between the two ports.
    Before the seal is again put in its place, the shaft of the pump should be turned by hand to see that it does not bind. In case of tight spots, tap the outer edge of the cover lightly until the gears turn smoothly.
    The seal may be reinstalled or replaced by reversing the procedure as outlined above. Put a few drops of clean lubricating oil on the seal seat before replacing 0F9 assembly. When tightening the nut 0L41, it is necessary to create about 7# pressure on this nut toward the seal. This is equivalent to compressing the seal .040".
    Before the pump is reinstalled it should be tested for freeness by revolving the shaft by hand.

    General Data..............................   5
    1.	BEFORE STARTING THE MOTOR. Fill the crankcase with high ejrade oil not heavier than S.A.E. i'o. 30. When temperature is below 32^ F., use oil not heavier than S.A.E. No. 10.
    A HEAVIER OIL MTJST NOT BE USED. The oil filler plug is painted blue and is located on top of motor base, with the motor level, remove filler plug and pour oil in opening until It rises to the level of the filler plug opening. Crankcase holds 4-1/2 pints. Fill air cleaner with light engine oil, (SAE lo) to the indicated oil level. See paragraph 62. Fill the gas tank with a good, clean, third grade gasoline. Tank holds five gallons. Do not mix oil and gasoline. See paragraphs 11 to 19.
    2.	HOW TO START. Open gasoline shut-off valve In gas filter or gasoline tank.
    A. HAND CRANK STARTFR TYPE. 'hill out the compression release rod as far as It will come, press the starter shaft In, to mesh gear with pinion on crankshaft. Crank rapidly and as soon as erough momentum Is gained let go of the compression release rod and pull carburetor choke lever toward you to choke carburetor. After motor starts, gradually open the choke valve until motor runs smoothly with the choke valve wide open. (A warm motor does not require as much choking as a cold motor.)
    3.	FAILURE OF MOTOR TO START. If motor falls to start after a reasonable number of trials do not make any adjustments until you have studied the Instructions referred to In the SERVICING REFERENCE CHART, on page 4.
    4.	HOW TO STOP. Press the stop switch mounted on the Intake elbow against the end of the spark plug. Hold It until motor stops firing. This will ground the spark.
    5	. GENERAL DATA. You will find your Briggs & Stratton motor substantially built. It Is made of high grade materials by skilled workmen, In a factory fully equipped with the most modern machinery. Before It was shinped, it received many tests and careful Inspections.

    6.	Your motor will give you better service if you do not tinker with it. This does not mean, h ewe ver, that it does not require a certain amount of attention. Give it the right kind of fuel, oil and care. Keep It clean both inside and out. You will be well repaid in trouble-free, satisfactory service.
    7.	If you should experience any difficulty, follow the Instructions referred to In the Servicing Reference Chart above. If you cannot easily remedy It, consult your dealer, or a nearby Briggs & Stratton Authorized Central Service Distributor.
    8.	OPERATING REQUIREMENTS. A gasoline motor to operate properly must have all parts In correct adjustment to provide good Ignition, carburetion, compression and cooling. And of equal Importance, the oil and gasoline used must be clean and of recommended grades. The following instructions fully explain the simple adJustments and offer operating recommendations that will assure you of complete satisfaction. We urge you to carefully observe them.
    9.	The reliability, economy and ease of starting which characterize this motor are due In part to the fact that It Is of the 4-stroke cycle design commonly called "4-cycle", the same design used In all automotive motors. As the name Indicates, there are four strokes to one complete power cycle.
    10.	HOW A 4-CYCLE MOTOR OPERATES. On the intake stroke the piston goes down, producing a vacuum In the cylinder, thereby drawing fuel up through the carburetor so that the space above the piston becomes filled with combustible gas. During this stroke the intake valve Is open Next the piston comes up on. the compression stroke with both valves closed. At the top of the compression stroke a spark occurs at the spark plug, firing the highly compressed gas. This produces an explosion above the piston which forces it down on the power stroke. Both valves are closed. On the next upstroke of the piston, called the exhaust stroke, the exhaust valve Is open, and the burned gases driven out. See plate No. 2.

    INTAKE STROKE COMPRESSION STROKE POWER STROKE EXHAUST STROKE
    11.	KEEP THE MOTOR CLEAN. it will pay you to keep your motor clean both Inside and outside. See that no dirt or water enters motor when filling with oil or gasoline. As a precautionary measure always wipe off the gasoline cap and oil filler plug, as we 11 as around them before refilling. Dirt In the motor or gasoline tank will cause trouble and even serious damage-. Also be sure to remove any dirt or grass that may accumulate In the flywheel housing or between cylinder fins.
    12.	USE THE RIGHT KIND OF OIL. Correct lubrication is Important. See paragraph 1. we recommend the use of Moblloll "Arctic" S. A. E. No. 30 or other high grade oil with similar characteristics having a low carbon residue and a body not heavier than S.A.E. No. 30. A heavier oil which might be satisfactory in a tractor or for lubricating farm machinery must NOT be used.. Do not mix oil with the gasoline. This 4-cycle motor Is provided with an Independent efficient pump lubrication system which forces a stream of oil to all moving parts of the motor. There are no external parts which require separate oiling.
    13.	ADD OIL REGULARLY. A motor which Is run without oil will be ruined within a few minutes. To avoid the possibility of such an occur
    ENGINE INSTRUCTIONS
    Page 7-E
    rence and the resulting expense, always fill the oil reservoir at the blue plug to the top of the filler plug opening after each five hours of motor operation. Capacity of oil reservoir is 4-1/2 pints.
    14.	CHANGE OIL FREQUENTLY. After every twenty-five hours of motor operation, the oil should be completely drained from the crankcase. Do not remove motor from its mounting base. Remove the yellow oil drain plug, located at either end of motor base, and let the oil flow into a pan or other receptacle you use. We do not recommend flushing out with kerosene. Replace the drain plug, refill with fresh oil and replace the blue filler plug.
    15.	In the normal running of any motor, small particles of metal from the cylinder walls, pistons and bearings will gradually work Into the oil. Dust particles from the air also get into the oil. If the oil Is not changed regularly these foreign particles cause Increased friction and a .grinding action which shortens the life of the motor. Sludge, a gummy mass, forms which clogs up the oil passages. Fresh oil also assists In cooling, for old oil gradually becomes thick and loses Its cooling as well as its lubricating qualities.
    16.	USF CLEAN GASOLINE. A good grade of clean, fresh gasoline Is recommended. Too high test gasoline may form vapor-lock In gas line when motor gets hot. This Interrupts the flow of gasoline and causes motor to stop. Be sure that the small vent hole In the gasoline tank cap is not clogged up, for air must enter the tanktoallow the gasoline to flow to the carburetor. Test by blowing through top of cap. See paragraph 18.
    17.	AVOID GUMMY GASOLINE. If you experience trouble with a gummy, sticky substance with a peculiar sharp obnoxious smell, change to another grade of gasoline. This gum comes from the gasoline and clogs carburetor, gas line, gasoline tank, etc. You'can check your gasoline by evaporating a half pint In an open dish. If a quantity of gum remains, try another kind that Is clean and fresh.
    18.	YOU CAN AVOID MOST TROUBLE FROM GUM IF YOU WILL KEEP THE TANK FULL WHEN YOU ARE NOT USING THF MOTOR-If you use it only occasionally, drain tank completely and rei111 when motor Is used again. The reason for this Is that evaporation of stale gasoline causes most gum deposits.
    19.	TO CTFAN THE FUEL LINES* Disconnect the gasoline line at the carburetor and also at the gas filter. Blow through the gas line to clear It. To clean the gas filter, first close the shut-off valve and loosen thumb screw. Remove and clean glass bowl, gasket and screen .Open shut-off valve to see If gasoline flows freely from the tank. IMPORTANT: IMPORTANT: If you find a gummy varnish-like substance, alcohol or acetone will dissolve It. See paragraphs 17 and 18.
    20.	CORRECT USE OF THE CHOKE. The correct carburetor setting (see paragraph 23) Fives the motor the best mixture to run on when It Is hot. For starting, It Is necessary to choke the carburetor to get a rich mixture, because cold gasoline does not vaporize readily. A warm or hot motor requires very little choking. Until you become familiar with your motor, however, you may make the mistake of not choking the carburetor enough or you may choke It too much. If motor falls to start after cranking three or four times with the choke closed, try crankIn^ two or three times with the choke part-way down and then all the way down, or open. Use motor choke the same as you use an automobile choke.
    21.	TO PRIME THE MOTOR.	The motor may fall to start for the
    reason that either the carburetor Is Incorrectly adjusted or dirty, or the fuel line Is dirty or clogged, or you are out of gasoline. To determine the cause, prime the motor by removing the spark plug and pour a half teaspoonful of gasoline into the spark plug opening. Replace the spark plu°- and crank the motor, if It fires for three or four revolutions and stops, the difficulty Is definitely In the fuel system. See paragraphs 19, 22 to 26. If motor will not fire at all, check the ignition system, see paragraphs 31 to 46, also compression, paragraphs 47 to 56 .

    22.	TO ADJUST THE CARBURETOR. The carburetor on this motor is of the gravity type. The gasoline Supply Is regulated by a needle valve. The throttle Is automatically controlled by the governor, see paragraphs 27 to 30.
    23.	To adjust the carburetor, completely close needle valve by turning to right or clockwise as far as possible. Do not screw up too tight or use force when closing needle valve, or needle valve may be damaged. From closed position, open needle valve one to one and one-quarter turns. After the motor has been started and warmed up make final adjustment with the choke wide open by turning the needle valve to the point at which motor operates most smoothly with full load. This setting will also take care of starting with use of the choke. When starting cold motor, If It Is necessary to keep choke partially closed several minutes before motor runs smoothly, carburetor setting Is too lean and needle valve should be opened a notch or two--turn to left. For governor adjustments see paragraphs 27 to 30. The Idle adjustment screw setting Is about a half to three-quarters of a turn open. Do not force screw against seat or you will damage both.
    24.	The throttle lever adjustment screw Is set at the factory to permit Idling speed of about 1200 R.P.M. We do not recommend adjusting the throttle to bring the speed lower. If you want to Idle the motor at a higher speed than 1200 R.P.M. turn the throttle lever adjusting screw to the right or In a clockwise direction. (Plate no. 3)
    25.	TO REMOVE AND REPLACE CARBURETOR. Disconnect gasoline line from carburetor and gasoline shut-off valve. Remove two cap screws and lockwashers from the Intake elbow. Then remove the cotter pin from the throttle shaft lever and slip the throttle link off. To replace, reverse the operations as performed above, use anew cotter pin If necessary.

    26* TO CLEAN CARBURETOR* Remove it from the motor as explained In the previous paragraph. Remove gas line connector elbcw. To disassemble carburetor, FIRST remove needle valve, stuffing box nut, packing nut gland and nozzle. Then remove screws and lockwashers from the upper carburetor body. CAUTION: The upper and lower bodies are Interlocked by the nozzle and failure to disassemble In above order will result In damaged parts. To check Inlet valve and seat, pull out brass pin holding carburetor float. A worn or dirty Inlet valve and seat or Incorrect float level will cause carburetor to leak, in reassembling, float should be In a horizontal position when It closes Inlet valve and seat. To check float, Invert upper carburetor body and place a scale or a flat, straight piece of steel across carburetor float and see that distance from top of float to carburetor body flange is equal at both sides of float. See plate No. 3A. The float hinge tang can be bent to attain proper position of float. If any parts are gummy, clean them In alcohol or acetone. Blow through all passages and openings. Do not use wire to clean out small holes. Replace worn or damaged parts.
    Carburetor Float Position Plate No. 3A
    27.	GOVERNOR—CORRECT MOTOR SPEED. The speed of your motor Is automatically maintained under varying loads by a centrifugal governor. It Is operated from the cam.gear.
    28.	The governor was carefully adjusted at the factory to maintain normal speed under load. Do not re-adjust unless absolutely necessary. It can be changed by reducing or Increasing the tension of the governor spring. Turn governor adjustment nut to the right or clockwise to increase motor speed. To left or anticlockwise to reduce motor speed. Recommended motor speed: 2200 to 3200 R.P.M. (Plate No. 3)
    29.	RESETTING GOVERNOR LEVER. If the governor lever has been loosened or removed from the governor shaft, it is easily reset. With the carburetor attached to motor and hooked up to governor lever with throttle link, loosen screw holding governor lever on the shaft. Push the governor lever toward the left as far as it will go. Hold it in this position and turn the governor shaft to the right with pliers until it strikes a stop In the crankcase. Tighten screw that holds governor lever to shaft until the lever is snug. Push governor lever to the right as far as it will go and tighten screw securely.
    30.	This motor is equipped with a hand idling device as shewn in Plate #4. To idle motor, lower the idling adjustment lever. Raise the lever to bring motor back to normal running speed.
    31.	THE IGNITION SYSTEM. The spark is produced'by a high tension magneto consisting of armature, condenser, contact points, and rotating magnets cast in a flywheel. This is a simple self-contained system which is very reliable. It also does away with batteries. The ignition current is sent into the motor cylinder through the ignition cable and spark plug. The magneto itself as well as the cable and spark plug must all be in proper condition and adjustment to Insure a good hot spark.

    37.	TO REMOVE AND REPLACE MAGNETO ASSEMBLY. After removing flywheel as explained In paragraph 35, detach the Ignition cable from the spark plug and remove the back plate, flywheel key, contact^ point dust cover and the four magneto mounting screws. Turn the crankshal-t so that the contact plunger holds the contact points open and then remove magneto assembly. To replace, reverse the operations and use the old gasket between the plate and crankcase, or, If damaged, a new gasket See Ref. No. 166 for proper thickness to get correct end play of .002" to .008" between magneto bearing and crankshaft thrust faces, as shown In plate No.8. Use lockwashers under mounting screws. Fhge 27.
    38.	MAGNETO TIMING. The magneto assembly Is always correctly timed with the motor when the flywheel Is assembled to the tapered crankshaft with a key and securely held In place with pinion gear and nut lock. Do not attempt to change the timing by relocating any parts or filing crankshaft timing flat. Always use soft key Ref. No. 79, page 22. If steel key Is used and flywheel becomes loose It will damage the keyway In the crankshaft.
