Crankshaft
Crankshaft
Like the previous model, the new 911 Turbo features a gas-nitrided crankshaft with a special surface hardness to transfer the high forces. The crankshaft is drop-forged, runs on eight bearings and has twelve balancing weights. The main bearing 4 is designed as a thrust bearing. Axial play is determined by two thrust plates, which are inserted at the left and right of the bearing. The main bearings are designed as plain bearings with a diameter of 63 mm. The drive mechanism for the two drive chains for the camshafts and demand-controlled oil pump is located on the pulley side.
