Camshaft Journal Diameter Grinding

Centreless grinding of crankshaft bearing journals is in many respects similar to camshaft grinding. The main differences are: Camshafts are rough ground directly from the cast condition, while crankshafts may have to be pre-turned. The diameter tolerances for crankshafts are often even tighter than those for camshafts.

The two main things are lobe lift and journal diameter. For example, a .420-inch lobe lift roller cam should finish around 1.028-inch base circle size. When you request a .900-inch cam, you are taking .128 inch of base circle diameter away, dropping the lifter down an additional .060 inch in the lifter bore.
