The crankshaft is manufactured from forged carbon steel C38 with induction hardened main bearing journals. The fillets of the main journals are fillet rolled to improve the strength of the crankshaft.
A five counterweight design has been used to balance bearing loads to give class-leading vibration levels.
An oil groove in the upper half of each main bearing transfers pressurized engine oil into the crankshaft for lubrication of both the main bearings and connecting rod bearings. The crankshaft assembly comprises the bare crank and a dynamic balancer shaft system drive gear. This gives direct drive at a ratio of 2:1 of the two counter-rotating dynamic balancer shafts.
Two individual thrust washers are located on either side of the central main bearing journal panel of the cylinder block to control crankshaft end float.
