Check (and exchange, if necessary) all corrosion anodes. If corroded away, the anodes must be
checked and exchanged at shorter intervals.
Empty the starting air bottles of water.
Clean the fuel filters at the front of the engine at suitable intervals. Exchange the inserts if they are in
a poor state.
Every six months or more often
Clean the seawater side of the cooler (the inner side of the pipes).
If the engine is smoking and the cause cannot be found in the fuel filters or the feed pump, check
whether the injector holes are worn. The injectors should be pressure tested, too. Pump by means of
the handpump up to 240 kp/cm²
Exchange of lubricating oil:
Heavily loaded engines: After about 500-700 working hours or according to oil analyses.
Other engines: After about 1000 working hours
Minimum twice a year.
The lubricating oil filter inserts should be replaced when oil is exchanged or when the pressure dif-
ference on the manometers "Before filter" and "After filter" exceeds 2 kp/cm² The turbocharger oil
must be exchanged every 1000 working hours.
Every year
Adjust valves and check the lubrication of the rocking levers.
Check the water pump valves.
Check the air distributor. Remove the cover and lubricate the disc valve.
Every 2 or 3 years
Change the clutch oil and the clutch oil filter. If water has come into the clutch, the oil must be
changed immediately. It may have to be changed several times until it is completely clear as new oil.
sThe clutch oil filter insert must be replaced at the same time as it dissolves in water.
Every 3 or 4 years or every 15,000-18,000 working hours
1 or 2 crank bearings must be dismounted for checking. Change the turbocharger bearings after
12,000 working hours.
If the engine is not started for some time, the opening of the exhaust pipe should be covered by a
bucket or a plactic bag to prevent rain and moisture from getting into the pipe, as it will loosen soot. If
may cause difficulties in starting the engine if this soot is jammed in the valves.
