Repair instructions

Dismantling

1. Drain the cooling water and the oil from the engine. Clean

externally afterwards. Loosen the water hose between the

gearbox and the sea -water pump and remove the gearbox.

3. Remove the rocker cover and the fuel pipe between the

pump and the injector and unscrew the rocker gear. Note!

Pull the rocker gear straight up since it is centred with a

guide pin 1. The other hole 2 is an oil channel.

2. Remove the generator and its drive belt, starter motor,

fuel filter and fuel pump with the drain-off pipe (be careful of

fuel spillage), coolant water pump with hose and thermostat

housing, dipstick, temperature and oil pressure sensors.

Unscrew and discard the oil filter.

4. Remove the push-rods 1, remove the cylinder head and

the cylinder head gasket. Take care of the washers 2 under

the nuts.
