The crankshaft is made from forged steel with induction hardened bearing surfaces.
The sprocket is crimped on the crankshaft's rearmost shank.
The crankshaft is supported by seven main bearings. The main bearings are replaceable main bearing shells. The sixth main bearing is a thrust bearing that holds the crankshaft in a determined position along the length of the axle.
An internal vibration damper is on the front end of the crankshaft. Inside the enclosed vibration damper, a circular flywheel works on a silicone fluid, which dampens the crankshaft torsion oscillations. The vibration damper gives longer service life for the crankshaft and smoother engine operation.
The energy that is generated in the vibration damper, is converted to heat, therefore, the unit is cooled with oil via the oil cooler pipe.
