Repair of Crankshaft

Reduce cost and breakdown time by Onsite Repair of Crankshaft

The failure of crankpin and main journal bearing causes serious damage to the crankshaft which are as following:

I) Development of excessive taper and ovality in Crankshaft, Crankpin and Main Journal.

II) Development of crack

III) Abnormal increase and decrease of hardness

IV) Loss of alignment of crankshaft resulting to the increase in deflection readings.

V) Development of bearing line marks, pitting, local depression

VI) Damage of radius fillet and lube oil profile

The removal of crankshaft from the engine block inevitably means high cost and disruption due to transportation and repair in the designated workshop. Removing and sending the crankshaft for repair to the workshop is now outdated.
