Engine Component Description: Crankshaft
WARNING: This page is about a different car, the 2002 Oldsmobile Aurora and 2001 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.
The crankshaft is a cast nodular iron design with four 70 mm (2.75 in) diameter main bearings. Crankshaft thrust is taken by the number three main bearing. The position sensor, also known as the reluctor wheel, is cast integrally with the crankshaft. The crankshaft is internally balanced and incorporates a two piece modular rear seal. The connecting rod journals are 55.455 mm (2.18 in) diameter. A rolled fillet radius is incorporated on all bearing journals to improve fatigue strength.
