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 taper and ovality of 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 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.
