Crankshaft Repair & Crankshaft Grinding by Crankshaft Grinding Machine – RA Power Solutions

Crankshaft Repair does not require crankshaft to be removed from entablature. In recent past due to seizure of bearing or development of taper, ovality, loss of alignment of crankshaft it was necessary to remove the crankshaft from the engine block and send it to the designated workshop for crankshaft grinding and crankshaft repair.

The introduction of lightweight, vibration-free crankshaft grinding equipment facilitates grinding of crankshaft, crankpin and crank main journal on the spot while the crankshaft is assembled in the engine block. There is no necessity of even decoupling of alternator and other accessories from the diesel engine. The portable crankshaft grinding machine is placed on the crankpin or crank main journal through the inspection window of the entablature and the grinding and polishing operation is done.

The crankshaft grinding machine is centre less, vibration free equipment which ensures that the centre line of the crankpin is maintained. The crankshaft grinding and crankshaft polishing is done in one setting.

The crankshaft grinding machine is manufactured by us of diameter ranging from 60 to 700 mm. The machine is simple and easy to operate. We also provide training at the customer’s site for the operation and maintenance of the crankshaft grinding machine.

Company has sold more than 65 crankshaft grinding machine all over the world which are performing satisfactory.

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.
