RA Power Solutions is based in New Delhi, India, undertaking crankshaft machining for the last 47+ years. Crankshafts are repaired on site without removing them from the crankcase. In case of any damage to the crankshaft, crankpin, and leading journal, we can machine it and polish it to a standard undersize within the manufacturer’s specification and tolerances specified.
The main advantage of repairing a damaged crankshaft and crankpin journal onsite is the short repair timescale. It is also more cost-effective. There is no need to remove the crankshaft from the engine block, pack it, or send it to a workshop. Machining and polishing can be done directly on-site. At the same time, all the specifications and tolerances as per the engine manufacturer are maintained.
RA Power Solutions has a team of experienced engineers who can repair all types of defects in the crankshaft and make it reusable.
Our scope of work includes the following:
- Crankshaft, Crankpin Repair
- Crankshaft Journal Repair
- Crankshaft Repair
- Crankshaft Straightening
- Crankshaft Regrinding
- Crankshaft Polishing
- Crankpin Machining, Crankshaft Journal Machining
We can undertake the repair and polishing of crankshafts with diameters ranging from 35 mm to 700 mm. Our technicians can fly to any part of the world at short notice. As they carry with them the Indian CDC. The machining of the crankshaft, repair of spare parts, engine overhauling, and maintenance can also be undertaken while sailing the vessel.
Our portable, lightweight onsite crankshaft grinding machine is designed to generate minimum vibration. Thus, maintaining a high standard of quality in terms of surface finish, taper, and ovality. Since we offer repair of primary spares, maintenance, and overhauling of engines, spares, etc. We own one point of responsibility for the satisfactory performance of the engine in totality.
We are considered to be the cheapest in the market in comparison to the competitors based in Europe.
We also have engine crankpin bearings available in our stock for various engine models from Wärtsilä, MAN B&W, Sulzer, Yanmar, Daihatsu, MAK, Caterpillar, Cummins, Deutz, Mitsubishi, Allen, Himsen, and Niigata.

FAQs
1. What is the difference between crankpin machining and crankshaft journal machining?
The crankpin is the part of the crankshaft connected to the connecting rod, and the main journal is the part of the crankshaft that is supported in the engine block through the main bearings. Crankpin machining is the process of restoring the crankpins, while crankshaft journal machining usually refers to machining the main journals. Both require precise control of the diameter, taper, ovality, and surface finish.
2. What is crankpin machining?
Crankpin machining is the process of restoring a damaged or worn crankpin to the size and surface condition required. It can remove defects such as scoring, wear, taper, and ovality. Depending on the crankshaft condition, the crankpin can be machined to a standard undersized size, maintaining the required manufacturer specifications and tolerances.
3. What are the advantages of onsite crankshaft grinding?
The most important benefit is that the crankshaft does not need to be removed from the engine for repair purposes. This helps in reducing downtime and saving costs for transportation. The portable grinder can be used for machining and polishing the crankpins and journals to meet the specified requirements. It is particularly applicable for the repair of marine engines, generators, compressors, and pumps.
