RA Power Solutions undertakes the repair of crankshafts having a diameter ranging from 35 mm to 700 mm. The concept of removing the crankshaft and sending it to the workshop for repair is now no longer valid, and the user gets the crankshaft repaired onsite.
During our working of more than forty years on marine main, crankshaft reconditioning, auxiliary engines, and high capacity diesel generating sets installed in industry, power plants, etc., we have observed that while the maintenance schedule stipulated by the engine manufacturer in the maintenance manual is religiously followed, but no attention is paid on the crankshaft’s condition.
Even during the maintenance schedule of 25,000 to 30,000 hours of operation, maintenance agencies and officials connected with the day-to-day upkeep of the engine ignore the inspection of the crankshaft till the seizure of bearing or any other major breakdown happens in the crankshaft.
Repair of Crankpin on Board a Vessel
We have experienced that irrespective of the metallurgy of the crankshaft and level of hardness after continuous operation of engine taper and ovality of the crankshaft, crankpin, and main journal are developed. The bearing surface becomes rough and in some cases bearing line marks, pitting, etc. is developed. Due to these abnormalities developed in the crankshaft, failure of bearing and crankshaft takes place. RA Power Solutions recommends that inspection procedures should be followed in order to ensure satisfactory performance of the crankshaft and to save it from rejection.
During the periodic maintenance schedule, the crankpins and main journals of the crankshaft should be checked for the development of taper and ovality.
The dimensions of the crankpin, taper, and ovality should be well within the limits specified by the manufacturers. There should not be any presence of bearing line marks or pitting on the crankpin journals.
The profile of the lubricating oil hole and radius fillet should be checked visually. There should not be any loss of the original profile.
The hardness test and the crack detection test by MPI or dye penetrant are not required till the major failure of the bearing or accident takes place.

Checking of deflection of the crankshaft.
Positioning of crankshaft balancing weights. They should be tightened on specific torque as per the manual.
In case the above preventive inspection is undertaken on-site without disassembly of the crankshaft, the user can avoid any major damage to the crankshaft.
Onsite Machining of crankpins and main journals has been made simple in this era of technological renovation. The concept of removing the crankshaft and getting the crankshaft machined in the workshop is no longer valid. The onsite crankshaft machining is undertaken to maintain strictly all the tolerances as specified by the manufacturer and stipulated in the maintenance manual.
Crankshaft machining is no longer the monopoly of a bunch of companies based in Europe and the UK. The availability of a portable, easy-to-operate crankshaft grinding machine it has made simple and easy to undertake the polishing and grinding of the main journal if required.
RA Power Solutions is a reputable and leading crankshaft grinding machine exporter and crankshaft reconditioning, known for its high-quality products and exceptional services. With a strong commitment to customer satisfaction, RA Power Solutions has gained a stellar reputation in the industry. Our state-of-the-art crankshaft grinding machines are designed to precision grind and polish crankshafts, ensuring optimal performance and longevity of engines.
