This results from excessive clearance due to bearing wear. Thus, the rod's big end bearing failure causes a grinding contact with the vehicle's crankshaft, as it starts to beat against it. Worn Belts and a Noisy Transmission. There are two major faces of a bearing. The first is the main bearing surface, and it is often prone to wear and tear.

Crankpin requirements further include perpendicularity, run-out and circularity of the bearing surface (e.g. 5 μm). To meet these requirements, crankshaft grinding is necessary. In terms of surface roughness, a typical R a requirement is 0.25 μm [266]. Another major requirement is waviness, as this affects the load-carrying capacity [135].
