Crankshaft Repair, Grinding and Polishing Onsite

Crankshaft machining and crankshaft polishing are undertaken by RA Power Solutions onsite. The Repair, Grinding, and polishing is done up to 700 mm diameter of any cylindrical shaft or crankshaft used in compressor, diesel engine, pump, or all types of rotatory equipment.

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.

Following are the main observations in case of failure of bearing:

  • Development of taper & ovality on crankpin & main journal diameter.
  • Dent, Bearing line marks, rough surface is observed on the pin.
  • In case of a severe accident, the bearing material gets heated and sticks on the crank pin or main journal diameter.
  • Due to overheating the crankpin becomes black/ blue and hard spots are developed.
  • Failure of bearing also causes the development of cracks.

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

RA Power Solutions specializes in machining of crankshaft 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 crankshaft repair services to leading shipping companies for more than four decades and our success rate is almost 100 percent.

In extreme cases where damage is more than the last limit the crankshaft is rejected, in fact, there are a number of 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 and 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 a number of crankshafts from rejection.

We undertake repair of all makes and models of diesel engine, compressor, pump, or all types of rotatory equipment. The most popular make & model of engines are Yanmar, Wartsila, Daihatsu, MAN B&W, Caterpillar, Deutz MWM & Allen Engine, etc.

We have been regularly executing the repairs in Argentina, Bahamas, Barbados, Bermuda, Bolivia, Brazil, Canada, Chile, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, El Salvador, Guatemala, Guyana, Haiti, Honduras, Jamaica, Mexico, Nicaragua, Malaysia, Nigeria, UAE, Togo, Spain, Madagascar, etc.
