Timing gears
The drive gear assembly consists of cylindrical gears with helically cut teeth.
The injection pump and camshaft are driven by the crankshaft via an intermediate gear.The engine’s lubricating oil pump is also driven by the crankshaft via an intermediate drive gear.
Apart from the camshaft,the camshaft gear also drives the sea-water pump drive gear (marine engines),as well as air compressor,if fitted (optional equipment) is also driven by the camshaft gear.
Crank mechanism
Crankshaft
The crankshaft is journaled in seven main bearings.The axial bearing consists of thrust washers located at the centre main bearing.The crankshaft is balanced both statically and dynamically.The front end of the crankshaft has a polygon profile and the rear end has a flange to which the flywheel is bolted.
The crankshaft is nitro-carbureted.Provided that the shaft does not need to be straightened before grinding,grinding to max.2nd undersize can be done without a renewed nitro-carburetion
