It is generally observed that due to non-experience or lack of knowledge of the companies undertaking crankshaft reconditioning and Onsite Crankshaft Machining, Crankshaft misguides the end user, resulting in serious breakdown and considerably higher expense.

Onsite Grinding of Crankpin by RA Power Solutions

RA Power Solutions has undertaken the reconditioning of crankshafts exceeding ten thousand numbers and recommends the following situation for the reconditioning of the crankshaft.

Recommendation for reconditioning of Crankshaft:

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 seizure 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 the reconditioning of the 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 the Crankshaft successfully.
