Engine Components: Crankshaft: Notes
This is a forged crankshaft with hardened running surfaces. A central hole through the main bearing and holes in the crank pin contribute to reducing the weight. To reduce fuel consumption, the main bearing diameters of the crankshaft have been reduced from 70 mm to 65 mm. This also enables the use of a double main bearing bolt connections without enlarging the crankcase. As on the N63 engine, the oil pump is driven on the flywheel side by the crankshaft. The camshaft sprocket is directly integrated into the crankshaft.
