engine again and pause for a few minutes to let the oil
gather in the crankcase. Check the level again and add
oil when necessary.
•
Check and tighten nuts, bolts, and unions, paying partic-
ular attention to the fuel system.
•
Observe the exhaust at the normal full load. The ex-
haust must be free from soot. Do not allow the engine
to run with a dirty exhaust without investigating the
cause as this may result in an expensive breakdown.
•
Check air vent (siphon breaker valve) on a regular
basis. When the air vent it not working properly, the
engine can fill up with water by siphoning. Water in the
combustion chamber causes serious damage to the
engine.
•
Check and readjust V-belt.
•
Check the electrical connections.
EVERY 150 HOURS:
•
Change oil.
•
Check the battery acid level (not for WhisperPower
batteries).
•
Check battery terminals for corrosion.
•
Check and readjust V-belt.
•
Check impeller raw water pump (durability depends on
the purity of the sea water. In sandy water and warm
water wear will increase).
When replacing the impeller the gasket between the pump
case and the cover should be replaced as well. So when
ordering a spare impeller order a gasket as well. Remove the
cover to get access to the impeller. Remove the old impeller
with the help of two screwdrivers. Install the new impeller
and add some grease. Turn the blades in the direction of
rotation of the pump.
EVERY 300 HOURS:
•
Replace the impeller of the raw water pump.
•
Retighten the cylinder head bolts and adjust the valve
clearance. (See paragraph 5.4.2).
•
Check air cleaner element.
•
Replace the oil filter.
•
Replace the fuel filter
Replacement depends on the condition of the fuel. We
recommend replacement every 300 hours.
EVERY 1000 HOURS:
•
Replace the V-belt.
•
Retighten cylinder head bolts/ check and adjust
valve clearance.
EVERY 2000 HOURS:
•
Check lubricating oil pressure.
•
Clean and check or replace fuel injector nozzles and
check injection pressure.
•
Check the air cleaner element:
•
The air is taken from the section between the alternator
and the engine
•
Check the cooling system:
The engine cooling liquid is indirectly cooled by
raw water via a heat exchanger. The seawater is
pumped by the PTO driven impeller pump. All parts
of the cooling system are of corrosion free and
seawater resistant materials such as naval brass
and copper/nickel. In case of gathering of dirt in
the system it could be cleaned by compressed air.
When overhauling the engine one could clean the
parts thoroughly or replace.
When the generator set runs less than 150 hours a year the
oil should be changed yearly.
4.3.1 Maintenance schedule
4.3.2 Taking out of service
When not using the generating set for a longer period it is
recommended to execute an engine preservation procedure.
1
Clean the engine.
2
Loosen the fuel suction pipe and fuel return and put
them in a can with preservation diesel fuel. Start the en-
gine and run the engine warm.
3
Drain the hot engine oil and refill with preservation oil.
4
Stop the engine and take loose the inlet of the raw water
pump. Drain the water from the water lock. Crank the
