MAINTENANCE

EVERY 300 HOURS:

•

Replace the impeller of the raw water pump.

• Retighten the cylinder head bolts and adjust the valve clearance. (Refer to § 5.4.2).

•

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/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 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 resistant materials such as 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
