Camshaft
The camshaft runs in borings in the engine block, and it has been forced-lubricated through
grooves bored in the engine block.
A bush for the camshaft is fitted in the front end of the engine block. There is a hole for lubricating
oil inlets in this bush.
The camshaft is fixed on to the engine block at the flange “A” on the sketch below.
The cams which are casted together with the camshaft are made of hardened steel.
The camshaft is driven via a gear-wheel from the crankshaft.
When dismantling the camshaft remove gear and rear end cover as stated in sections R and G.
Then loosen the camshaft at the flange “A” on the sketch below and take it out.
