The crankshaft repair process has been simplified by RA Power Solutions with the minimum amount of engine downtime possible by the introduction of lightweight, compact onsite crankshaft polishing equipment. The engine block is used to insert the polishing and grinding machine, and the crankpin is polished. The onsite crankshaft grinding and polishing machine is capable of maintaining a surface finish better than the international standards, i.e., 0.2 RA value.

The failure of the crankpin or main journal bearing is common which damages the crankpin and main journal diameter of the crankshaft.

The following are the main observations in the case of the failure of the bearing:

1. Development of taper & ovality on crankpin & main journal diameter.
2. Dent, bearing line marks, and a rough surface are observed on the pin.
3. In a severe accident, heat causes the bearing material to stick to the crank pin or main journal diameter.
4. Overheating turns the crankpin black or blue and creates hard spots
5. The failure of the bearing also causes the development of cracks.

Specialization of RA Power Solutions in Crankshaft Machining, Grinding, and Polishing:

RA Power Solutions specializes in the machining of crankshafts without removing them from the engine block. Our highly trained technicians reach the accident site in the minimum possible time with portable equipment to undertake the repairs.

We have been extending crankshaft machining and onsite crankshaft repair services to leading shipping companies for more than four decades. Our success rate is almost 100 percent.

In extreme cases where damage is more than the last limit, the crankshaft is rejected. There are several occasions where RA Power Solutions have successfully repaired the crankshaft under deviations.

In this case, we have undertaken the crankpin machining beyond the undersize recommended by the manufacturer.

Our team of highly skilled engineers and technicians utilizes the latest technology. The equipment to deliver precise, reliable, and cost-effective onsite crankshaft machining and polishing services.

We understand the importance of minimal downtime for our clients. Our onsite services save you time and money by eliminating the need to transport heavy crankshafts to a workshop.

The matching bearings are also supplied by us. This initiative has saved several crankshafts from rejection.
