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.
Crankpin 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.
Portable Crankshaft Grinder
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.
The company has sold more than 85 crankshaft grinding machines all over the world, which are performing satisfactorily. The machines are priced low and are ideally suited for large engineering, shipping companies, repair workshops, etc. More than 10000 Crankshafts are successfully repaired by us, which is a record.

Crankshaft repair is possible without removing the crankshaft from the block. In case of failure of the bearing, it is generally observed that the crankshaft is damaged. While it is easy to replace the bearings, it is a challenging proposition to undertake the repair of thecrankshaftand put the engine back into operation.
Crankshaft Repair on Board a Vessel
Removal of the onboard crankshaft repair from the engine block inevitably translates to a high cost of repair and downtime. RA Power Solutions undertakes the repair of the crankshaft onsite without removing it from the engine block. The portable, lightweight crankshaft grinding machine is taken to the site by experienced technicians to undertake crankshaft repair by grinding.
The important parameters before crankshaft repair are checked, like taper and ovality, hardness, crack, physical profile of lube oil, and radius fillet etc. If all the major parameters fall within the stipulated tolerances of the manufacturer’s specifications and tolerances, crankshaft repair is undertaken.

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.
Engine bearings for crankpin and main journal are manufactured by RA Power Solutions Pvt. Ltd. We also maintain stock of standard and undersized bearings in tri-metal and bimetal of popular make and model of engines.
Alternator Bearing of Wartsila 12V32
White Metal Bearing of Deutz Engine
After grinding the crankpin and main journal of crankshafts, undersize crankpin bearings and main journal bearings are required. It is observed that engine manufacturers most of the time do not have an inventory of undersized bearings, thus delaying the assembly and commissioning of the engine.
