3861277 Volvo.Penta Flywheel

D379 and D398 Engines are equipped with a combination sump pump and prelube hand pump. After a prolonged shut down, or after a filter and oil change, operate the hand pump to fill the lube system oil passages before starting. See the LUBRICATION AND MAINTENANCE PROCEDURES, Engine Lubrication System, Section D, for further details.3. Check oil level(s) on driven equipment. 4. Check the fuel tank level. Keep the fuel tank full. See Section F - Fuel Tank Maintenance. 5. Check the engine jacket coolant level. Maintain coolant level to the base of the fill pipe. See Section G - Checking Coolant Level. 6. Open the raw water valve (if so equipped) on the engine jacket heat exchanger system.7. Reset shutoff devices. See the topic, ATTACHEMENTS, Emergency Shutoff Devices and Alarms. 8. Open the fuel supply valve.
The fuel return line must be open to prevent engine damage.
9. If air has entered the fuel system, prime the fuel system. See the LUBRICATION AND MAINTENANCE PROCEDURES, Section F - Priming the Fuel System.
PRIMING PUMP ON 6 CYLINDER ENGINE
PRIMING PUMP ON V-ENGINE10. Disconnect any battery charger which is not protected against starting motor drain.11. Disengage the clutch, or open the circuit breaker on an electric set.
Do not start an engine under load.
12. Move the governor control lever to half engine speed position or to speed limiter stop. 13. Prime the raw water pump if necessary. (Only water pumps equipped with a water reservoir and fill plug require priming.) If the raw water pump is of the type shown below, the pump is a self priming pump. This pump does not have a priming chamber or fill plug.
SELF PRIMING RAW WATER PUMPPriming The Raw Water Pump:
The priming chamber must be filled with water before starting the engine to prevent pump or engine damage. After the engine is started, increase engine speed immediately to obtain and maintain system flow.
1. Carefully loosen the fill plug. If water is present immediately tighten the plug; the pump is full.2. If water is not present, pour approximately two gallons (7.5 liters) (1.5 Imp. Gals.), or until overflow occurs, into the fill hole.3. Install the fill plug.
FILL PLUG4. Start the engine at fast enough speed to obtain the normal water flow from the overboard raw water discharge or water cooled exhaust pipe.If the proper flow is not observed, stop the engine and repeat this procedure. If the pump does not hold water in the priming chamber, the water pump seals should be replaced.Starting The Engine
Do not engage the starter when the flywheel is moving.
Electric Starting:
1. Use starting aids if required. See the topic, GENERAL, Cold Weather Starting. D349 and D399 Engines: When the START switch is turned to the START position, a prelube pump driven by an electric motor will pressurize the engine lubrication system with oil. The crankcase oil will develop sufficient pressure before closing a switch which will energize the starting motor(s). The starting motor(s) will then crank the engine. After the engine starts, the starter switch is released, the prelube pump stops and the engine oil pump continues lubricating the lube system.Prelube time will vary with the temperature of the oil. Hot oil will require more time to attain oil pressure before the engine can crank than will cold oil.2. Push the START button; or turn the HEAT-START switch to the START position, depending upon the control the engine has. Release the control as soon as the engine starts. For electric sets, place the AUTO-MAN switch in the MAN position; place the ON-OFF-STOP switch in the ON position to crank the engine. As soon as the engine starts, move the switch to the OFF position. (The STOP position is used to stop the diesel engine.) If the engine fails to start in a few seconds, move the governor control lever to the fuel off position, then continue to crank for 10 seconds. This will clear the cylinders of unburned fuel.If the engine fails to start after 30 seconds of cranking, allow the starter to cool for 2 minutes before repeating the starting procedure.
Prolonged cranking at low oil pressure can energize the mechanical safety shutoff which is used on 5.4" bore and larger engines. If the reset lever is in the shutoff position, reset the mechanical shutoff control.
RESETTING MECHANICAL SHUTOFF CONTROL
NEVER use starting aids when the engine is warm and running.
If the engine is equipped with either a Woodward PSG or UG8 Governor, see the topic, WOODWARD GOVERNORS for the governor operation instructions.Air Starting:
1. Open and close the bleed valve on the bottom of the air tank to drain condensation and oil carryover.2. Check the air supply pressure. The air start must have 100 PSI (7 kg/cm2) to operate properly.3. Check the oil level in the oiler jar. Keep jar at least half full. Add oil if necessary. See the LUBRICATION AND MAINTENANCE PROCEDURES, Section H - Filling Motor Oiler.4. Pull the air valve upward to crank the engine. As soon as the engine starts, release the valve. The engine governor may be controlled by an air regulator valve. One control panel can regulate several synchronous operating engines.
