Crankshaft Grinding information - RPM

2020-1-27  CRANKSHAFT grinding Indexing. When a crankshaft is turned to an undersize, it can and does change the stroke and degrees apart of each rod journal. To index a crank, first the machinist has to know where the stroke and degrees (swing) are. Once this is established, with the right machine to start with, the crankshaft can be indexed for both ...

Crankshaft Damage - Diesel Engines Are Way More Prone

2021-10-1  The crankshaft can wear past the point of grinding and have to be replaced. And, if the crankshaft looks like this the con-rod is most likely not resizable. The crankshaft can bend severely or even break in some cases. If the crankshaft does break; the damage may be so bad, that you may have to replace the whole engine.
