Raw/Sea Water Pump Failure
The raw/sea water pump circulates sea or fresh water through the engine jacket water heat exchanger. If the raw/sea water pump should fail, follow the procedure below to continue engine operation.
Shut off valve-normally closed (1), emergency raw/sea water pump (2), emergency raw/sea water inlet (3), inlet valve-normally closed (4), emergency raw/sea water strainers (5), normal operation raw/sea water strainers (6), normal operation raw/sea water inlet (7), inlet valve-normally open (8), raw/sea water pump (9), jacket water heat exchanger (10), raw/sea water outlet (11), and aftercooler (12).1. Stop the engine. If the shaft bearing has failed, the pump does NOT need to be removed.2. Close inlet valve (8) to raw/sea water strainers (6) and raw/sea water pump (9).3. Open inlet valve (4) to emergency raw/sea water pump (2). Start and prime the pump.4. Start the engine. Engage the marine gear and continue operation at normal speed.Engine Lube Oil Pump Failure
If the engine lube oil pump fails, the oil pressure will drop and the engine jacket water temperature gauge reading will be above normal. The applicable engine shutoff controls (if equipped) will stop the engine. Refer to the following procedure to use the emergency lube oil pump.1. Place the marine gear in the NEUTRAL position. Stop the engine (if the engine is still running).2. Measure the engine oil level. Ensure the oil level is between the ADD and FULL marks on the dipstick. Add oil if necessary.3. Reset the oil pressure shutoff control (if equipped). Be sure that the oil pressure shutoff control RESET is in the RUN position to enable engine starting.4. Start the emergency standby lube oil pump. Observe the oil pressure gauge5. Start the engine. Engage the marine gear and operate the vessel at normal speed.Turbocharger Failure
Air cleaner (1), turbocharger air inlet hose (2), compressor (3), clamp (4), cartridge (5), turbine housing (6), oil supply line (7), aftercooler air inlet hose (8), and oil drain line (9).1. Remove air cleaner (1) and turbocharger air inlet hose (2).2. Remove oil supply line (7) from the top of cartridge (5). Remove oil supply line (7) from the cylinder block. Plug the oil supply opening in the cylinder block.3. Remove oil drain line (9) from the bottom of cartridge (5). Remove oil drain line (9) from the flywheel housing. Plug the oil drain opening in the flyheel housing.4. Remove the bolts from the flange to aftercooler air inlet hose (8).5. Remove clamp (4) while supporting compressor (3) and aftercooler air inlet hose (8). Remove aftercooler air inlet hose (8), compressor (3) and cartridge (5) as a unit.
DO NOT allow exhaust gas to discharge into engine room. Vent the exhaust to the outside and be sure venting systems are correctly installed and operating. Diesel engine exhaust contains products of combustion which may be harmful to your health.
6. Provide some means of attaching a flat steel against the opening in turbine housing (6) where cartridge (5) was removed. The plate must be large enough to completely cover the opening.
