What is Crankshaft Grinding? - Capital Reman Exchange

The main reason crankshaft grinding is done is because the crank wears over time. Over thousands miles the end play between the crankshaft and the bearings increases. When the "fit" between the bearings and the crank isn't perfect it lowers oil pressure and decreases lubricity. The less oil to the crank the faster it can wear out.
