In situ Machining Service and Repair of Crankshaft


RA Power Solutions undertakes in situ machining and repair of crankshaft of 2-stroke and 4-stroke engines installed in power plants, ships, and for various other applications.

We offer in situ machining services and repair of crankshaft up to 700 mm in diameter. With the concept of in situ machining the grinding and repair of crankshaft are executed in place without removing the crankshaft from the engine block. This reduces the downtime of the engine.

In the case of shipping industries, it is rather impossible to remove the crankshaft and send it to a workshop for repair. In situ machining of the crankshaft is becoming popular even for the high-capacity generators installed in power plants.
