Crankshaft: Description and Operation

Crankshaft Assembly
The crankshaft has ground journals which are hardened by an induction hardening process. This provides a surface finish with hard-wearing properties.

There are four main bearings. Lubrication is provided through drilled oilways in the crankshaft. All main bearings are replaceable. The No.2 and No.3 main bearings have no grooves in the bearing caps.

The sensor wheel for the engine management system is screwed to the crankshaft.
