What is Crankshaft Grinding? - Capital Reman Exchange

Indicators that a journal needs grinding include if the surface has wear and make it rough to the touch. Sometimes the journal will be knocked out of center and needs to be surfaced to round and straightened. Consequently, the journal diameter could be positioned out of square at both end of the pins.
