Design And Function: Crankshaft
The crankshaft is made of forged steel and has induction hardened bearing surfaces. The crankshaft has five bearings with a main bearing diameter of 60 mm. The upper bearing half on main bearing 4 also acts as a thrust bearing or 180° bearing. The thrust washer is larger than usual to maintain the bearing surface with only one thrust washer. A gear is shrunk onto the crankshaft between cylinders 3 and 4. The gear drives the balancer shafts. In front of the main bearing is a gear that drives the oil pump. The crankshaft has a vibration damper positioned in the front pulley. Crankshaft weight is 15.2 kg, excluding gears.
