The crankshaft is manufactured from forged carbon steel C38 with induction hardened main and pin bearing journals. The fillets of the main journals are fillet rolled to improve strength. The fillets of the pins are induction hardened due to the split pin design, improving the strength of the crankshaft.
The crankshaft is installed in 5 main bearings. The 8 counter-balance weights provide low vibration levels, and the large main bearing journals are designed to contribute to stiffness.
An oil groove in the upper half of each main bearing transfers the oil into the crankshaft for lubrication of the connecting rod bearings. A thrust washer is installed each side of the top half of the center main bearing.
