Onsite Crankshaft Grinding & Polishing by Revolutionary Portable Equipment – RA Power Solutions

Crankshaft journal and crankshaft crank pin diameter should be grind and polished to attain a surface finish of 15 microinches or better. Again, the maintenance of the taper and ovality of the crankpin and crankshaft main journal has to be within the limit recommended by the manufacturer. Generally, the limits are within 0.02 to 0.05 mm, depending on the diameter of the crankpin and main journal. Till few years back it was a monopoly of a few European companies undertaking onsite crankshaft grinding and crankshaft polishing jobs charging exorbitant prices from the shipping companies and the power plants who had no option but to get the job of onsite crankshaft grinding and crankshaft polishing done from them.

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