Despite the fact that the crankshaft is made of forged steel, it has been found that after extended use, the taper and ovality of the crankpin and main journal exceed the engine manufacturer's recommended limitations. There is no other way to get rid of excessive taper and ovality than to onsite grinding of crankshaft, or if the ovality is not too severe, polishing the crankpin and main journal. The Crankshaft grinding process shows visible bearing line marks, pitting, and rough surfaces. The cause could be due to low bearing quality, non-replacement of lubricating oil filters on schedule, or poor lubricating oil quality.
