incorporates a basic engine model known variously as 499 4107 and4108 You will notice continual references to these three model the workshop portion of this manual They are used to the three major engineering changes already made to the engineThe diesel engine closely resembles the gasoline engine inasmuch as the mechanism is essentially the same Its cylinders are arranged above its its crankshaft is one of the same general type as that of a gasolineengine it has the same sort of valves camshaft pistons connecting rods andlubricating system and reverse and reduction gearThere it follows to a great extent that it requires the same treatment as thatwhich any intelligent and careful operator would give to a gasoline engine andthat gross negligence such as running the engine short of oil with sludged oildirty filters or with water boiling will have the same expensive diesel engine does differ from the gasoline engine however in the methodof handling and firing its fuel Carburetor and ignition system are done awaywith and in its place is a single component the Fuel Injection Pump whichperforms the functions of care and attention at the factory have resulted in an engine capable of many hundreds of hours of service What the manufacturer cannotcontrol however is the treatment the product will receive in service Thispart rests with youWhenever service parts are ordered always give complete description and partnumbers with engine model and serial number as an example Please supply For Whaleboat Marine Engine No ED7153480 10 of 15559 Oil Filter CartridgeThe

time they are RIGGING AND LlFnNG moved whereas the lag bolt stays in position and the nut on top is used to tighten the engineThe engine is fitted with two lifting rings de down or is removed to permit the engine to besigned so that the engine may be lifted without lifted The bolt itself stays in position at alldamage Location of these is shown in Fig 4 times as a stud and the bond between

Misalignment between the engine and the proThe coupling must not only transmit the power peller shaft is the cause of troubles which areof the engine to turn the shaft but must also blamed often on

main bearings is attempted make absolutely certain that the correct replacements are available reference to the relevant parts list will ensure this but for identification purposes the new bearings should have an annular groove machined in the inner bearing face along the centre line of the feed holes when the bearings are correctly located these feed holes will correspond exactly with those machined in the cylinder block On later 4107 and 499 engines the annular oil groove in the main bearing parent bore cylinder block and bearing cap has been deleted Adequate lubrication is maintained by repositioning the oil feed holes radially in the shell bearings and continuing to machine the annular groove in the bearing on theH1 centre line of these feed These later type shell bearings may be

September 17 1976 BULLETIN NUMBER 10MODEL Westerbeke 40 and WPDS 1015SUBJECT Sea Water Pump Clearance and Al ignment Clearance Adequate longitudinal clearance between the sea water pump shaft and the driving shaft is established by the use of multiple pump gaskets The number of gaskets required can vary from 1 to 4 Enough gaskets must be used so that the shaft ends do not mate See figure 1 WATER PUMP GAKtTS DRIVE SHAFT DRIVER PUMP SH4FT DRWN NOTE The application of liquid or paste type Prussian blue at pOints indicated by arrows will give positive indications of pump drive contact which will require the use of additional gaskets If the proper clearance is not maintained the sea water pump shaft will force the fuel pump drive hub against its bushirg The bushing will seize to the drive hub and rotate in its housing Bushing wear and loss of oil pressure will result When replacing the sea water pump be sure that the same number of gaskets is replaced and there is the required clearance Alignment Alignment is just as critical as clearance The latest 1211 pump intentionally has no pilot because the location of the timing cover itself is not precise To assure that the pump shaft is axial with the driving shaft install the pump with the four nuts just snugged WITH THE FUEL STOPLEVER OFF crank the engine for a few seconds If the nuts have not been overtightened the drive tang will cause the pump to align itself It is best to deliberately offset the pump against its studs so you can visually verify movement of the pump as it centers itself during cranking The nuts should then be tightened This procedure must be repeated anytime the pump is loosened J H WESTERBEKE CORP AVON INDUSTRIAL PARK AVON MASS 02322 5171 5887700 CABLE WESTCORP AVON TELEX 82 PIN 16742 V3 SERVICE BULLETIN

Connecting Pressure Sensing Devices to Oil Galleries Oil pressure sensing devices such as senders and switches must never be connected directly to any oil gallery of an engine The reason is simply that continued engine vibration causes fatigue of the fittings used to make such a connection If these fittings fail the engine loses its oil pressure and very quickly seizes Such pressure sensing devices must be bulkhead mounted and connected to the oil gallery using an appropriate grade of lubricating oil hose Any fittings used to connect the hose to the gallery must be of steel or malleable
