About Cummins Crankshaft Repair of QSK60-G4

Cummins engine crankshaft of QSK60-G4 was damaged of a diesel generating set installed in a power plant on one of the islands in the Maldives.

The Cummins QSK60-G4 is a high-RPM engine with a compact design. The officials at the diesel power plant were informed about the damage to one of the crankpins.

The details are as follows:

In order to execute onsite grinding of the damaged crankpin having a standard diameter of 120.65 mm, RA Power Solutions developed special tooling that is compact and capable of grinding the crankpin and main journal of the crankshaft. Two technicians, equipped with a compact, lightweight, dedicated crankshaft grinding machine, visited Addu City, Hithadhoo Island, Maldives.

The following job was carried out:

i) The complete inspection of damaged crankpin number 3 was undertaken to assess the damage. The minimum and maximum sizes observed are as follows: 

• Maximum Diameter 120.65 mm
• Minimum Diameter 120.09 mm

The above shows an ovality of 0.56 mm, which is considered to be very high.

iii) The grinding of crankpin number 3 was undertaken using our specialized onsite crankshaft grinding equipment, and a final size of 119.63 mm was maintained.

RA Power Solutions can undertake onsite grinding of crankshafts having diameters as small as 80 mm. We can extend these services all over the world.
