MAINTENANCE
EVERY 300 HOURS:
•
Replace the impeller of the raw water pump.
•
Check valve clearance.
•
Replace the oil filter.
•
Replace the fuel filter
Replacement depends or the condition of the fuel.
We recommend replacement every 300 hours.
Isolate the fuel supply and change the element.
EVERY 1000 HOURS:
•
Replace the V-belt.
•
Retighten cylinder head bolts/
valve clearance.
EVERY 2000 HOURS:
•
Check lubricating oil pressure
•
Clean and check or replace fuel injector nozzles
and check injection pressure.
•
Check the air filter element:
The air is taken in via the cover on the alternator.
Below this cover is a spongy material which filters
the air and holds some electrical components
which are cooled by the inlet air. This filter does
not require regular maintenance. Only in very
dusty circumstances this filter should be cleaned.
The spongy material can be washed in solvent or
replaced.
•
Check the cooling system:
The engine cooling liquid is indirectly cooled by
raw water via a heat exchanger. The alternator is
cooled by seawater which is pumped by the PTO
driven impeller pump through the cooler elements
in the generator housing. All parts of the cooling
system are of corrosion free and seawater resis-
tant materials such as naval brass and gunmetal.
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 100
hours a year the oil should be changed
yearly.
4.3.1 Maintenance
schedule
4.3.2 Putting out of service
When not using the generator for a longer period it is re-
commended 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
engine 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 engine having the raw water inlet sucking
anti freeze from a can until the pump, heat exchanger
and manifold are filled.
5
The coolant can stay in the engine.
6
Disconnect the battery and stock it in a place dry and
free of frost and charge it regularly.
7
Close inlet- and outlet openings with tape.
8
Protect the generating set against the influences of
bad weather conditions.
This way of preservation will be sufficient for 6 months.
Repeat step 2, 3, and 4, every 6 months. Change oil
before using the engine again.
