Water Pumps
Check the valves of the cooling and bilge pump (see mounting instructions 7-62).
Circulation Pump
Check the circulation pump. On the lower side of the bracket are two holes. One of them is con-
nected to the shaft packing ring which is blocking the engine oil, and the other is connected to the
carbon ring packing gland which is blocking the water. When the engine is running, ensure that
nothing comes out of the holes and that the holes have not been blocked.
Check whether there are cracks in the hose connections.
As to withdrawal of rotor - see 7-12.
Cooler
Check and clean the oil and freshwater coolers in accordance with maintenance directions 7-10.
Clutch and Reversal
Check the crossbar bolt for pull rod for wear and tear.
Check and, if necessary, replace the corrosion anodes in the clutch oil cooler.
When failure of clutch pressure is experienced: Check clutch filter and oil level of the clutch. The oil
level must be sounded when the engine is idling (disengaged).
Check the over-pressure valve: No oil must leak during reversing manoeuvres. Check the reversing
mechanism before calling at a port, especially after prolonged journeys. Reduce the engine revs to
250 rpm and reverse from ahead to astern.
Lubricating Oil Analyses
While engine is running, drain off approximately 2 litres of oil at the flange under the lubricating oil
filter. Then drain off the oil sample.
