Engine population is rapidly increasing for the shipping industry, power plants, and various applications. In most cases, engines are used not only for emergency purposes but as a base load. The continuous running of the diesel engine results in wear and tear of the crankpin and main journal of the crankshaft. In certain cases, taper and ovality more than the permissible limit is developed in the crankpin and the crankshaft main journal.

Crankshaft Grinding Executed on Board a Vessel – RA Power Solutions

RA Power Solutions has executed successfully the crankshaft grinding of 6 pins on board a vessel at Dumai/Lubuk Gaung Port, Indonesia of MAN B&W STX 6L23/30H Engine.

In this case, crankshaft grinding was required because all the CR pins having a standard diameter of 185 mm developed taper and ovality. Out of 6 CR pins, not even a single pin was seized or crack was developed.

**Crankshaft Deflection and MPI Test Under Process**

The above observations show that the engine users should periodically get the crankshaft calibrated and go for grinding and polishing as the crankshaft develops taper and ovality due to continuous running.

To execute the above job, RA Power Solutions Pvt. Ltd. used a crankshaft grinder which is lightweight, and the crankshaft grinder was taken to the site. RA Power Solutions has sold more than 60 crankshaft grinding machines all over the world.
