I) It is recommended to undertake crankshaft repair in case taper and ovality exceed the limit specified in the maintenance manual of the engine manufacturer.
II) In case of an accident, deep line marks or depression are developed.
III) Reconditioning of the crankshaft is recommended in case higher hardness is observed due to the seizer of bearings or any other reason.
IV) Development of surface crack.
V) Loss of alignment.
VI) In certain cases, although the dimensions of the CR Pin and Main Journal are observed within the limit, due to the rough surface observed on the CR Pin and of the Main Journal, the surface requires polishing.

The above suggestions are given for reconditioning of crankshaft. It is always advisable to send photographs and a brief Inspection report to RA Power Solutions for free recommendations as to how to repair Crankshaft successfully.
