Draining If it is not possible to keep the engine compartment free of frost, the seawater system must be drained to prevent freezing damage. . Always use protective gloves for work which includes contact with oil, fuel etc.
Remove the fixing screws and nuts on the pump. Air filter housing, heat exchanger and coolant pump with spacer D1-13 removed. . . Replace with a new anode if 50% of the material has perished or at least once per season. Open the filler cap slowly, and release the pressure in the cooling system if the filling cap or tap has to be opened, or if a plug or coolant hose has to be removed when the engine is hot. The thrust washers is machined into the holder for the main bearing Crankshaft end play, mm in.

Remove the gudgeon pin circlips and remove the gudgeon pin carefully, with a suitable mandrel. Fill up with coolant to the correct level. Inspection and measurement of piston and cylinder bore Check the pistons for cracks and worn piston ring grooves. . Avoid opening the coolant filling cap when the engine is hot.
Remove the Woodruff key from the crankshaft. If one cylinder has lower compression pressure than the others, the reason can be poor valve sealing, broken piston rings or a damaged cylinder head gasket. Spare parts Spare parts for electrical- and fuel systems are subject to various national safety requirements, such as U. All glowplugs are electrically connected by a busbar. They may cause an explosion in the inlet manifold.
