Crankshaft: Description and Operation

The crankshaft has ground journals which are hardened by an induction hardening process. This provides a hard-wearing surface finish. There are four main bearings. There are lubricating oil channels drilled in the shaft. 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.
