Cylinder head
The cylinder head is manufactured of specially alloyed cast iron. It is provided with replaceable valve seats for the inlet valves.The cylinder head is screwed onto the cylinder block with screws. The tightening of the cylinder head should be done in three stages.

Cylinder block
The cylinder block is cast in one piece of specially al- loyed cast iron.

Pistons, piston rings
The pistons are manufactured of a light-weight metal al- loy. They are fitted with three piston rings (chromium- plated) – two compression rings and an oil ring.

Camshaft
The injection pump is driven from the front part of the camshaft by means of two or three separate cams (de- pending on the number of cylinders).
The feed pump is driven via an eccentric cam from the rear of the camshaft.

Timing gears
The timing gears consists of cylindrical gears with be- velled cogs. The camshaft and sea water pump are driven from the crankshaft gear via an intermediate gear. The engine’s oil pump is built into the intermediate wheel and is driven via this. Regulator weights are suspended in the front edge of the camshaft gear.
