RA Power Solutions is based in New Delhi, India, undertaking crankshaft machining for the last 40 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 the repair of the damaged crankshaft, and crankpin journal on site is that it requires a very short repair timescale. It works out to be cheaper to get the onsite crankshaft machined and polished as there is no need of removing the crankshaft from the block, packing and sending it to the designated workshop. At the same time, all the specifications and tolerances as per the engine manufacturer are maintained.
