Crankshaft Repair in Limited Engine Space – RA Power Solutions

RA Power Solutions Pvt. Ltd. have successfully executed crankshaft repair on board a vessel of Hyundai engine. The crankshaft repair companies based in Norway, Singapore, and UK were invited to execute the grinding operation on crankshaft bearings of which were seized due to lube oil pump failure. These companies were not able to execute the repairs due to non availability of compact portable tool which was required as the space available from the inspection window was less.

Knowing the constraints of space, RA Power Solutions Pvt. Ltd. designed and manufactured a special-purpose crankshaft grinding machine which was inserted from the inspection window, and grinding of 6 nos. pins was successfully executed. The engine is performing satisfactorily.

The repair of crankshaft on site was possible because the crankshaft grinding machine designed by RA Power solutions was compact, lightweight and was manufactured according to the size of the window and space available in the crankcase of the engine. The technicians were able to maintain the tolerance after grinding within 20 microns against the stipulated tolerance of 30 microns in the manufacturers manual.

Importance of Hardness in Crankshaft – RA Power Solutions

The hardness of crank pin and main journal of crankshaft is of great importance for the satisfactory performance of the crankshaft. In case of low RPM diesel engine, the crankshafts are not hardened and the hardness is achieved by the metallurgical properties. In case of high RPM engine, crankshafts are hardened. The most common process followed by the manufacturers of crankshaft grinding machine is to go for induction hardening.

Due to seizure of bearings, the temperature goes high and the hardness increases. The increase in hardness makes the crankshaft brittle resulting to the development of crack.

RA Power Solutions Pvt. Ltd. suggests that whenever seizure of bearings takes place it is important that crankshaft hardness is checked and presence of crack should also be checked either by dye penetrant process or Magnaflux.

In cases of this form of failure, it is typically seen that hardening occurs, which results in the development of hard spots and hard areas next to the soft sections, even up to the scale of 700 HB. According to the manufacturer’s specifications, the extraordinarily high increase in the crankpin journal hardness is not desirable so the crankshaft is heated up and annealed.
