Crankshaft Assembly

The crankshaft has ground journals which are hardened by an induction hardening process. This produces a hard-wearing surface finish.
There are four main bearings and lubricating oil channels are 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 bolted to the crankshaft.
