What is Crankshaft Grinding? Capital Reman

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. When you reduce the size of the bearings you reduce the overall surface

Engine Crankshaft: Crank Grinding .010”/.010”

27/03/2017 One crankshaft manufacturer tested some shafts that were ground down to .010˝, .020˝, .030” or even .040” undersize and found that there was less than a 4% reduction in the fatigue life of the undersize shafts. Most crankshafts are engineered to be about four times stronger than required, based on mathematical stress and load calculations, so a 4% reduction in fatigue life is virtually
