It is important that the crankshaft is initially inspected by experienced technicians in order to detect the fault after the damage or accident.

**Inspection of Crankpin Under Process**

The following are the major parameters that are examined before the repair of the crankshaft:

The minimum and maximum diameter of the crankpin and main journal, taper, and ovality are checked.
Run out of main journals and deflection readings are taken to verify the loss of alignment.
A complete non-destructive test using MPI and ultraviolet lamp for heat cracks is undertaken of crankpins and the main journal of the crankshaft.
The crankshaft is also subject to a hardness test.

Based on the preliminary inspection reports prepared by the technicians, the repair procedure is planned. The onsite crankshaft grinding machine used for the crankshaft repair is lightweight and is placed on the damaged crank pin from the inspection window of the engine block. There is no requirement to remove the crankshaft from the Entablature and send it to the workshop, as bench-type grinders are now outdated.

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.

RA Power Solutions offers precision crankshaft grinding services, restoring your engine’s efficiency and durability. Trust our experts to deliver unparalleled results. Contact us for superior crankshaft solutions.
