J and E Engineering Crankshaft Regrinding Page

These measurements are then checked against the original engine manufacturer specifi ions and tolerances. If this data is not obtained then the crankshaft must be re-ground to the next size of bearings available. Bearing sets are usually available in undersizes of: .25mm .5mm and 1mm. This allows the crankshaft to be reground by these same amounts.

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