MAIN PANEL This manually-controlled WESTERBEKE diesel generator is equipped with toggle switches on the engine's control panel and, optionally. at a remote panel. All three switches arc momentary contact type and serve the following functions: 4.
DIESEL FUEL, ENGINE OIL AND ENGINE COOLANT DIESEL FUEL ENGINE COOLANT Use fuel that meets the requirements or specification of Class 2-D (ASTM), and has a cetane rating of #45 or hetter. WESTERBEKE recommends a mixture of 50% antifreeze and 50% distilled water. Distilled water is free from the chemicals that can corrode internal engine surfaces. Care Of The Fuel Supply The antifreeze performs double duty.
PREPARATIONS FOR INITIAL START-UP PRESTART INSPECTION A CAUTION: When starting the generator, it is This section of the manual provides the operator with prepa~ ration, initial starting. break-in, starting (warm or cold) and stopping procedures. Follow the procedures as presented for the conditions indicated and your WESTERBEKE generator set will give reliable performance and long service life.
STARTING/STOPPING PROCEDURE Should the engine not start when the START switch is depressed for 10 to 20 seconds, release both switches and wait 30 seconds; repeat the procedure above and preheat longer. Never run the starter for more than 30 seconds. THE STARTING SYSTEM Westerbeke diesel generators usc electric starters assisted by glow plugs for both normal and cold weather starting. The illustration below shows a cross-sectional view of one cylinder.
STARTING/STOPPING PROCEDURE STARTING UNDER COLD CONDITIONS High Water Temperature Switch Make sure the lubricating oil conforms with the ratings for the prevailing temperature. Check the table in the ENGINE OIL section in this manual. A high water temperature switch is located on the thermostat housing.
GENERATOR BREAK-IN PROCEDURE DESCRIPTION CHECK THE FOLLOWING Although your engine has experienced a minimum of one hour of tcst operations at the factory to make sure accurate assembly procedures were followed and that the engine operated properly, a break-in time is required. The service life of your engine is dependent upon how the engine is operated and serviced during its initial hours of use. D Monitor the control panel gauges. o Check for leaks of fuel and engine oil.
THE DAILY OPERATION CHECK LIST START THE GENERATOR Follow this check list each day before starting your generator. (See STARTING PROCEDURES nn previous pages). Allow the engine to warm up for 5 to 1() minutes to reach an operating temperature of 140" to 150"F (60"·66"C) before applying AC loads. Apply loads systematically allowing the generator to adjust to cach load before applying the next. Check the gauges for proper oil pressure, operating temperature, and DC voltage.
MAINTENANCE SCHEDULE A WARNING: Never attempt to perform any service while the engine is running. Wear the proper safety equipment such as goggles and gloves, and use the correct tools for each job. Disconnect the battery terminals when servicing any of the engine's DC electrical equipment. NOTE: Many of the following maintenance jobs are simple but others are more difficult and may require the expert know/edge of a service mechanic.
MAINTENANCE SCHEDULE NOTE: Use the engine hour meter gauge to log your engine hours or record your engine hours by running time.

ENGINE COOLING CIRCUIT DESCRIPTION When the engine is started cold, external coolant flow is prevented by the closed thermostat (although some coolant flow is bypassed around the thermostat to prevent the exhaust manifold from overheating). As the engine warms up, the thermostat gradually opens, allowing full flow of the engine's coolant to now unrestricted to the external portion of the cooling system. Westerbcke marine diesel generators are designed and equipped for fresh water cooling.
ENGINE COOLING CIRCUIT Refilling the Coolant Replacing the Thermostat After replacing the manifold drain plug, run thc engine at idle and slowly pour clean, premixed coolant into the manifold. Remove the cap screws and disassemble the thermostat housing as shown. When installing the new thermostat and gasket apply a thin coat of sealant on both sides of the gasket before pressing it into place. Do not over-tighten the cap screws.
ENGINE COOLING CIRCUIT Changing the Raw Water Pump Impeller Close the raw water intake valve. Remove the pump covcr and, with the aid of two small screwdrivers, carefully pry the impeller out of the pump. Install the new impeller and gasket. Move the blades to conform to the curved cam plate and push the impeller into the pump's housing. When a<>sern- bling, apply a thin coating of lubricant to the impeller and gasket. Open the raw water intake valve.
FUEL SYSTEM DIESEL FUEL FUEL INJECTION PUMP Use No.2 diesel fucl with a cetane rating of 45 or higher. Do not use kerosene or home heating fuel. The fuel injection pump is the most important component of the diesel engine and, therefore, calls for the utmost caution in handling. The fuel injection pump has been thoroughly bench-tested and should not be tampered with.
FUEL SYSTEM FUEL FILTERS Changing the Fuel Filter/32.0 KW 1. Shut off the fuel supply. The fuel injection pump and the fuel injectors arc precisely manufactured and they must receive clean diesel fuel, free from water and dirt. To ensure this flow of clean fuel, the fuel must pass through at least two fuel filters, a fuel water separator and the engine's spin-on fuel filter. Visually inspect, clean, and change these filters according to the maintenance schedule in this manual. 2.
FUEL SYSTEM BLEEDING (PRIMING) THE FUEL SYSTEM!20.0 KW AND 25.0 KW FUEL PRESSURE GAUGE The 20 KW and 25.0 KW generators have a connector for an in-line gauge at the secondary fuel filter .This gauge will indicate the fuel inlet pressure. A positive fuel supply should read 2.5 to 3.5 psi. Pressure below 1.5 psi will result in poor engine performance. Low pressure indicates unclean fuel from the fuel water separator filter. A fuel pressure gauge can be purchased thru your local marine store.
ENGINE OIL CHANGE Engine Oil Change 1. Draining the Oil Sump. Discharge the used oil through Oil COOLER the sump drain hose (attached to the fronl of the eogine) while the engine is warm. Drain thc used oil completely, replace the hose in its bracket, and replace the end cap securely. OIL FILTER (25 KW • 32 KW) NOTE: Thread size for the luhe oil drain hose capped end is 1/4 NPT. _ Always observe the used oj I as it is removed.
REMOTE OIL FILTER (OPTIONAL) INSTALLATION To install, simply remove the engine oil filter and thread on WESTERBEKE's remote oil filter kit as shown. Always install this kit with the oil filter facing down as illustrated. This popular accessory is used to relocate the engine's oil fiIteT from the engine to a more convenient location such as an engine room bulkhead. Contact your WESTERBEKE dealer for more information.
DC ELECTRICAL SYSTEM ENGINE 12-VOLT DC CONTROL CIRCUIT GLOW PLUGS The engine has a J 2 vall DC electrical control circuit that is shown on the wiring diagrams that follow. Refer to these diagrams when troubleshooting or when servicing the DC electrical system on the engine. The glow plug is a small heater installed in each pre-combustion chamber. They run off the engine starting battery and become red hot when activated. The glow plugs are wired through the preheat solenoid.
DC ELECTRICAL SYSTEM/ALTERNATOR DESCRIPTION I. Start the Engine The charging system consists of an alternator with a voltage regulator, an engine DC wiring harness, a mounted DC circuit breaker, and a battery with connecting cables_ Because of the use of integrated circuits (Ie's) the electronic voltage regulator is very compact and is mounted internally or on the 2. After a few minutes of running measure the starting battery voltage at the battery terminals using a multi-meter set on DC volts.
DC ELECTRICAL SYSTEM!ALTERNATOR E. Now check the voltage between the alternator output Alternator is Working terminal (B+) and ground. If the circuit is good. the voltage at the alternator should be the same as the battery, or if an isolator is in the circuit the alternator voltage will be zero. If not, a problem exists in the circuit between the alternator and the battery. Check all connections - look for an opening in the charging circuit. 4. Check the voltage of the service battery.

GENERATOR INFORMATION USE OF ELECTRIC MOTORS Generator Frequency Adjustment The power required to start an electric motor is considerably more than is required to keep it running after it is started. Some motors require much more current to start them than others. Split-phase (AC) motors require more current to start, under similar circumstances, than other types.
THE BE GENERATOR SINGLE AND THREE PHASE DESCRIPTION CIRCUIT BREAKER This generator is a four-pole, brush less, self-excited generator which requires only the driving force of the engine to produce AC output. The copper and laminated iron in the exciter stator are responsible for the self-exciting feature of this generator. The magnetic field produced causes an AC voltage to be induced into the related excitor rotor windings during rotation.
