The forged crankshaft has ground, induction-hardened bearing journals. This provides a hard surface to protect against wear. The crankshaft has five main bearings integrated in one common bed plate, the middle bearing acting also as thrust bearing. Passageways are drilled in the shaft for lubricating oil. All the main bearing shells are exchangeable.
