    The bearings are matched to maintain the proper clearances for oil flow at the new diameter of the journal. The main reason for grinding a crankshaft is as stated but there are some side benefits to doing the grinding. First yes it does lighten the overall weight of the crankshaft but overall it doesn t do that much to create a huge difference.

    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.
