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

Crankshaft Repair does not require the crankshaft to be removed from the entablature. In the recent past, due to seizure of bearings or development of taper, ovality, or loss of alignment of the 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 the crankshaft, crankpin, and crank main journal on the spot while the crankshaft is assembled in the engine block. There is no necessity for even the decoupling of an 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 centreless, vibration-free equipment which ensures that the centre line of the crankpin is maintained. The crankshaft grinding and crankshaft polishing are done in one setting.

The crankshaft grinding machine is manufactured by us with a 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.

FAQs:

Can a damaged crankshaft be repaired?

The only safe way to repair a crankshaft is if the damage is contained within the pins – you can grind them to undersize. Any other damage would, unfortunately, mean a new crankshaft is required. Bad news, but much better than the risk of blowing the whole engine

Is a crankshaft easy to fix?

It should be remembered, though, that in all cases, crankshaft repair is a highly specialised area of engine repair that requires the use of specialised equipment, having expert-level knowledge about crankshaft repair procedures, and possessing technical skills that take several years to acquire.

What is the crankshaft in a diesel engine?

The crankshaft is essentially the backbone of the internal combustion engine. The crankshaft is responsible for the proper operation of the engine and converting a linear motion to a rotational motion.

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, nor was a crack 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 lightweight 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.
