After assembly joint should be taped to prevent corrosion or preferably assembled using a sili con grease which can be obtained at an electronic store such as Radio ShackSAFETY PRECAUTIONS Never operate engine with inadequate ventilation Do not touch moving parts during operation Do not touch hot parts such as exhaust pipe and do not place com bustible materials near Inspect and adjust parts of the engine only after it is stopped Check and refill engine oil cooling water and fuel after the engine is brought to a stop In checking the water level for refilling remove the pressure cap only after the water temperature has fallen enough to prevent a steam burn Always use tools that fit cor rectly and use caution dur ing ser vicing Be sure that current carrying wires are protected from abrasion and that all connections are tight 4BREAKING IN YOUR NEW ENGINE While your engine has had individual test operations sufficient todemonstrate accurate assembly and correct operation of all systems itstill requires break in time Service life of your engine is dependent on how your engine isoperated and serviced during the initial twenty hours of operation Your new engine needs twenty hours of conditioning operation forbreaking in each moving part thus maximizing performance and life ofeng Ine Perform this condi tioning carefully keeping the in mind 1 Start engine run idle while checking that all systems are functioning sea water pump oil pressure battery charge 2 Warm eng ine preferably by running propeller at fast idle while tied down until water temperature gauge moves into the 130 140 degree range 3 Then use engine at moderate load 60 for first five hours 4 Avoid rapid acceleration 5 Use caution not to overload engine Grey or black smoke is a sign of overload 6 Next fifteen hours may be run at 70 75 in a new enine is basically a seating of the piston ringsto the cylinder walls This is not accomplished by long per iods ofrunnIng idle nor by early running under full load nor by varyingloads with intervals of fast acceleration andor excessive speedIdle running may glaze the cylinder walls causing oil consumption andsmoky operation Excessive speeds and loads may score cylinder wallswith similar resultsAs indicated above use a short warm up at idle and put engine undermoderate load and speed for the first five hours of operationo Forthe next fifteen hours use approximately 70 load rhis kind ofcareful operation will result in best results from your engine steps as shown below in starting your engine for the first timeor after a prolonged shutdown1 Fill your engine with oil up to 011 fillerport or near the upper limit on the dipstick Use a good grade of oil with API specification of CC or better For quantity of oil you may refer to the General Specifications page However it is best always to be guided by dipstick measure ment as angle of installation has some effect2 Your engine is supplied with a coolant recovery system to which the following instruc tions apply a Fill engine completely to the neck of the manifold cap b Then fill the recovery tank to the bottom level line Need for adding coolant is indicated when a cold engine has coolant level below the bottom level line c In winter add antifreeze as described on page 16 Anti freeze may be used year round if changed annually3 Fill the fuel tank with Diesel fuel The interior of the fuel tank must be maintained clean Be careful not to allow intro duction of dirt when filling fuel 4 Engine oil coolant and transmission levels should be checked at least once a day prior to engine use 6STARTING panel description and use of Note 1 When engine is stopped after use the water temperature and oil pressure gauges may stay at their running readingsNote 2 When eng ine is next to be used turn start swi tch to ON The temperature and pressure gauges will ZERO and the volt meter will register battery voltage The electric fuel pump mounted on the engine will also begin to operate purging any air accumulated in the systemNote 3 The engine is now prepared for starting 7STARTING PROCEDURES1 Turn the starter switch to the liON posi tiona If making an ini tial start after layup fuel filter servicing or repairs allow fuel pump to work lS2S seconds to purge the system of any air Check that clutch is in neutral and that throttle is in full forward2 Glow plug preheating with key in 1I0N II position push in about 14 inch or enough so that voltmeter indicates dis charge Hold key in depressed posi tion until glow plugs are sufficiently hot Follow Table below for preheating time Quickheat type Yl14T Atmospheric temperature Preheating time SC 41F or higher Approx 10 sec SC 41F to SC 23F Approx 20 sec SC 23F or lower Approx 30 sec Limit of continuous use 1 minute3 Proper glow plug function is indicated by vol tmeter drop when key is depressed This drop will be slight but dis cernible If no voltage drop is noted it may indicate defecti ve glow plugs or a faulty preheat circuit check for loose connection 84 Starting Continuing to hold the key depressed turn to the START position The starter motor will run thereby cranking the engine Hold throttle open until engine runs and then reduce throttleShould the engine not start even when the starter switch is left ats position for 10 seconds take your hand off the starter switch for30 seconds and then attempt to start the engine again by the glow plug The starter motor should never be allowedto run for more than 30 seconds at a time5 Operation As soon as the engine has star ted release the key The key will automatically return to the ON posi tiona Leave the key at ON dur ing oper a tion Check that wi th eng ine running oil pressure and bat tery charge voltage are registering and that raw water is discharging with the exhaustDuring engine operation do not turn the key to s position Thismay damage the starter motor6 Warmup operation Run a few minutes at IDLE position to assure that all functions are operating Then operate under reduced load until water temperature rises into the 140150 range 9STOPPING PROCEDURE1 Stop To stop the engine move the throttle control through the idle position to stop As the throttle is moved past idle there will be increased resis tance to movement because a spring loading must be over come Hold the throttle firmly against the pressure until the engine comes to a complete stop2 Starter switch off Wi th the eng ine stopped turn the starter key back to OFF position The battery will be discharged if the key is left at ON position An engine alarm buzzer is provided to warn the operator of this possibility Best precaution is always to remove the keyCAUTIONS ON STARTING AND OPERATION1 Normal starting Follow the procedures below for routine starting of your engine I Check the engine and transmission oil levels and refill if necessary 2 Insure that you have sufficient fuel Keep tank as full as possible 3 Check cooling water level and refill if necessary Note Check for leaks of water or oil particularly lhen signs of such leak are found on the bottom of the egine or in the drip tray 4 Start the engine in accordance with the procedures given on the preceding pages 5 Allow the engine to warm up to 140150 F before placing the engine under heavy load2 Starting under cold conditions The following three adverse conditions concur as the atmospheric temperature drops exceedingly and the engine must under such conditions be started by taking steps described below LUBRICATING OIL TURNS VISCOUS Make certain that viscosity is proper for the prevailing atmospheric temperature Check the oil also for deterioration Study page 12 10 VOLTAGE ACROSS BATTERY TERMINALS DROPS Check that the battery is fully charged THE TEMPERATURE OF INTAKE AIR IS LOW AND COMPRESSION TEMPERATURE DOES NOT RISE ENOUGH Allow the glow plug to operate sufficiently to aid starting See table on page 83 Cautions during operation Confirm that the oil pressure is normal during normal operation Confirm that exhaust gas is as follows While engine is cold White smoke When the engine grows warm Almost smokeless When the engine is overloaded Some black smoke Check for abnormal noise such as knocking fr iction or leaking sounds and vibration and blowback sounds Check for leaks of fuel and engine oil A knocking sound is heard while the engine is cold during quick acceleration and at idle Confirm that no knocking sound is heard in other cases Photo above is right hand side of WlOtwo wi th 2 1 reverse and reduction gear Note convenient cable attachment brackets for clutch and throttle accessible filter location and lube oil drain hose 11 REQUIREMENTS FOR PROPER SYSTEM1 Engine oil For engine lubrication use diesel engine oil Diesel engine oils are classified according to the API Specifications into grades CA CB CC and CD Anyone of them is usable but use of CC or higher grades prepared by wellknown makers is recommended2 Engine oil viscosity Use oil having viscosity best suited to the atmospheric tem perature Use of an allseason oil SAEIOW30 with minimum visco sity change under different temperatures is suggested 20C 6SF or higher SAE 30 or 1W30 SAE 20 or 10W30 SC 41F or lower SAE IOW30 3 Oil pressure The oil pressure during operation of the engine is indicated by the oil pressure gauge During normal operation Oil pressure will range between 50 and 70 PSI At the time of cranking Pressure will rise proportion ately with speed4 Engine oil change To renew engine oil discharge old oil through the sump drain hose attached at front of engine while engine is still warm Drain old oil completely replace the hose plug the end securely and add fresh oil through the oil inlet port on the valve cover After refilling oil idle the engine for several minutes and stop Then check the quantity of oil by the oil level gauge Fill to but not over the high mark on the dipstick Always observe old oil as it is removed A yellowgrey emulsion indicates presence of water in the oil While this condition is rare it does require prompt attention to prevent serious damage 125 Replacement of oil filter Being a replaceable cartridge type the oil fil ter requires no cleaning inside In installing the oil filter apply eng ine oil th inly on to the Oring and then tighten it by hand firmly When removing the used fil ter cover over with a plastic bag This will allow both filter element and spilled oil to be collected cleanly without spilling oil in the bilge Note A After market filters are not recommended since the material standard or diameters of important items might be entirely different from genuine parts Note B Immediately after filter change and oil fill run engine to ensure that oil pressure is normal and that there are no oil leaksFUEL SYSTEM1 Diesel fuel USE 2 DIESEL FUEL NEVER USE KEROSENE OR HEAVY OIL In cold weather particularly water vapor is produced by conden sation when air is present in the fuel tank The tank therefore should be kept full as much as possible The fuel tank furthermore needs to be kept completely free of dirt and water2 It is required that a primary fuel filter of the water entrapment type be installed betvleen the fuel tank and the eng ine Such a fil ter shovln her e is avail able under Par t 32974 from your local Wester beke representati ve or your boat builder rrhis fil ter adapted for boat builder use comes complete wi th fi t WATER LEVEI tings for either hose or metal INDICATOR tubing Mount in an accessible RING place inspect often and drain off water accumulation fre quently 133 Notes on fuel system See on facing page a typical explode view of a fuel system for a two cylinder engine It is also illustrative of the selfbleeding system used on the Westerbeke 3 KW marine generator set The Westerbeke selfbleeding fuel system is automatic in opera tion While it is unlikely that the operator will be forced to service the system at sea the possibility does exist Therefore it is recommended that the following parts be carried onboard Banjo washers s 11 30 31 33 34 45 Injector seat washers 42 Lift pump filter and gaskets s 6 7 8 Fuel filter element and gaskets s 13 14 15 I f a leak should develop at a banjo or washer that cannot be remedied by a simple tightening of the screw renew the washers The engine can be started by taking the steps described on pages 8 and 9 In cases where the engine cannot be started easily loosen two injection nuts on the nozzle side turn the speed control lever to full open position turn the starter motor and then tighten the nuts firmly4 Cleaning fuel filter and replacing filter element After the first 50 hours of operation loosen the retainer ring 16 and discard filter element 15 Clean bowl 17 and reinstall new filter using new gasket 13 and 14 This same treatment is required of the filter element 6 in the fuel lift pump Similarly replace new filter element 6 using new gasket 7 and 8 After the first 50 hour change the change period may be increased to 200 hours or once per season5 Fuel injection pump The fuel injection pump is one of the most important components of the diesel engine and thus it calls for the utmost caution in handling Furthermore the fuel injection pump has been thoroughly shopadjusted and should never be readjusted care lessly Such adj ustment whenever necessary should be per formed at an authorized service station as a precision pump tester and skills are required To obtain long and satisfactory use of your injection pump Always use fuel which is free from impurities Clean and renew the fuel filter periodically Inspect water entrapment filter regularly 14If a water trap type filter see page 13 is not interposed between the fuel tank and engine lift pump any entrained water willtend to lay in bottom of lift pump Internal metal parts of thelift pump will rust Particles will pass on to filters and eventually to injection pump and injectors with damaging and many boat builders do supply a water trap filter there aresome who do not It is to prevent such omission that a trap filter as a desirable optionalextra at moderate cost It is supplied with fittings for eitherhose piping or metal tube pipingOrder it wi th the eng ine install it in an accessible placeinspect it daily and drain as needed 1510 Cooling water As cooling water use soft water with least impurity content such as tap water potable water or rainwater and never use hard water or foul water Use of hard water or water containing much impurity will lead to collection of scale in the engine and heat exchanger with resultant decline in cooling effects2 Antifreeze In cold districts care should be taken to prevent cooling water from freezing Cooling water itlhen frozen expands to break the heat exchanger and the cylinder block f and it is essential that antifreeze be added to cooling water in a quantity proportional to the lUvlest temperature of the district It is recommended that the antifreeze mixture be used throughout the yearo Antifreeze of poor quality or without rust inhibitor will cause corrosion of the cooling system Always use antifreeze prepared by a reliable maker and never use it mixed with antifreeze of a different brand Make sure that the cooling system of the engine is cleaned well before adding antifreeze Recommended antifreeze for year round use is ZEREX or PRESTONE vIi th rust inhibi tor ANTIFREEZE ADDITION DATA Antifreeze Concentration 13 23 30 35 45 50 60 Freezing c 5 10 15 20 30 40 50 t eEEa t r E C F 23 14 5 4 22 40 58 Note It is advisable that antifreeze concentration be selected on the basis of a temperature which is about 5C 106F lower than the actual atmospheric tem perature expected 3 Fresh water cooling system The system consists of a sea water pump which pumps raw sea water through a heat exchanger to remove heat from the coolant The raw water is discharged overboard through the exhaust line The engine coolant fresh water with or without antifreeze is circulated by the fresh water pump in continuous circuit pumped through the cylinder block cylinder head heat exchanger and back to the fresh water pump 16The total system is very reliable and requires only a daily checkof the water level in the system plus routine check of hose clampsand fittingsIt is likely that zinc electrodes will waste away from contactwith sea water It is also possible for the raw water pumpimpeller to fail due to lack of sea water or deter ioration Anearly sign of impeller failure is less water and more steam at theexhaust through hull fittingIt is recommended therefore that zinc electrodes 11885 waterpump belt 32942 alternator belt 13585 sea water pump assembly32617 and sea water impeller kit 32620 be carried onboard at alltimes These parts should be ordered from your nearest stockingdealer and used as inspection dictates 17Alternator belt and water pump tension The belts are properly tense if they deflect 10 to 12 mm 039 to 047 in as they are de pressed wi th a finger between the pulley and pulley of the long distance side Excessi ve tension can cause quick wear of the belt and bearings of the water pump and the al ternator Excessive slackness or presence of oil on the belt on the other hand can lead to engine overheating and insufficient charging due to a slipping belt CAUTION Never attempt to adjust tension of the fan belt while the engine is in DIAGRAMYour engine is of 12V system and its electric circuit is as shown indiagram 24666 shipped loose with this manualFor installing electrical parts connect them correctly by referringto the diagram and at the same time check for damaged wire sheathingand confirm that grounding is provided properly Care must always betaken while working on the electrical

described in thefollowing pagesBREAKING IN Service life of your generator is dependent upon how the engine isoperated and serviced during the initial 10 hours of operation Your new engine needs at least 10 hours of conditioning operationfor breaking each moving part in and maximizing performance and lifeof engine Perform this conditioning carefully bearing the in mind1 Since generator sets operate at 1800 RPM to obtain 60 cycle current your control of the breaking in process is limi ted to control of load2 Do not ever attempt to BREAK IN your generator set by running at NO LOAD3 Immediately on starting the set add approximately 25 load to cause a fast warm up4 For the first 10 hours of operation run between 20 and 60 percent load5 After 10 hours you may load as needed except that6 You must avoid overload at all times Overload is signalled by smoky exhaust andor a reduction in speed and in a new engine is basically a seating of the piston ringsto the cylinder walls This is not accomplished by long per iods ofrunning idle nor by early running under full loadIdle running may glaze the cylinder walls causing oil consumption andsmoky operation Excessive loads may score cylinder walls with similar resultsAs indicated above use a short warm up period under moderate load forthe first ten hours of operation For the next forty hours 70 load This kind of careful operation will result inbest results from your engine 25STARTING panel description and use ofNote 1 When generator is stopped after use the water temperature and oil pressure gauges may stay at their running readingsNote 2 When generator is next to be used depress preheat switch The temperature and pressure gauges will ZERO and the volt meter will register battery voltage The electric fuel pump mounted on the engine will also begin to operate purging any air accumulated in the systemNote 3 The generator is now prepared for starting See next page for specific instructions 26STARTING PROCEDURES1 If making an initial start after layup fuel filter ser vicing or repairs depress the preheat switch for 15 to 25 se conds This will energ ize the fuel pump allowing it to purge the system of any

motor is considerably more than is required for keeping it running after it 1S once started Some motors require much more current to start them than others Split phase AC motors require more current to start them under similar circumstances than other types They are commonly used on easy starting loads such as washing machines or where loads are applied after the motor is started such as small power tools Since they require 5 to 7 times as much current to start as to run their use should be avoided whenever possible if the electric motor is to be driven by a small generator Capacitor and motors require from 2 to 4 times as much current to start them as to run them The current required to start any motor varies with the load connected to it An electr ic motor connected to an air compressor for example will require more than a motor to which no load is connected In general the current required to start 115 volt motors con nected to medium starting loads will be approximately as follows MOTOR AMPS FOR AMPS FOR SIZE RUNNING STARTING 16 32 64 to 224 14 46 92 to 322 13 52 104 to 728 12 72 144 to 292 34 102 204 to 408 1 13 26 to 52 Note that in the above table the maximum amps for starting is more for some small motors than for larger ones This is because the hardest starting types splitphase are not made in larger sizes Because the heavy surge of current required for starting motors is required for only an instant the generator will not be damaged if it can bring the motor up to speed in a few seconds of time If difficulty is experienced in starting motors turn off all other electrical loads and if possible reduce the load on the electric motor2 Required Operating Speed Although individual units and models may vary slightly the normal voltage and frequency of typical 60 cycle enginedriven generators described in this book are approximately as follows when run first vii th no load applied then at half the generator capaci ty and finally when loaded to its full capacity as rated on the nameplate 31 Generator Voltage Load Speed l15v 230v AEElied 4 Eole Freguency Plants Plants None 1830 61 129 258 Half 1800 60 120 240 Full 1755 58 115 230 The output

Maintenance See the engine instruction book for engine maintenanceo BRUSHES Check the brushes for ylear after about 1000 hours of operation and every few hundred hours of operation thereafter They should be replaced when worn down to one half inch Whenever replacing brushes or removing them to do other service work remove one brush at a time and put the screws back into the brush holder to hold the wire terminals on place so there will be no difficulty replacing the wires correctly COlviMUTATOR A commutator in good condi tion has a glossy finish and is brownish in color If it gets greasy rough or dirty it may be cleaned with very fine sandpaper Do not use emery cloth BEARINGS All ball bearings used in these generators are packed with grease before assembly no further greasing is required If they become rough or worn they should be replaced 32 11SV f 11SV 115 V AC END IC EXCITATION FIELD M MBEARING RECTIFIER RECTIFIER IRTURE AC AC IITERNAL 3 4 3 IRE 120240 SOUND GUARD
