Crankshaft Reconditioning | Crankshaft Grinding Machine Exporter – RA Power Solutions

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 The concept of removing the crankshaft and sending it to the workshop for repair is now no longer valid, and the user gets the crankshaft repaired onsite.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 the 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 the 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., are developed. Due to these abnormalities developed in the crankshaft, failure of the bearing and the crankshaft takes place. RA Power Solutions recommends that inspection procedures be followed 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.

Inspection of Crankpin on Board a Vessel

Checking of deflection of the crankshaft.
Positioning of crankshaft balancing weights. They should be tightened to a 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.

On-site 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 has made it 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 reconditioner, known for its high-quality products and exceptional services.

**Crankpin After Grinding & Polishing by Crankshaft Grinding Machine**

Onsite Crankshaft Grinding & Polishing By Revolutionary Portable Equipment – RA Power Solutions

Crankshaft journal and crankshaft crank pin diameter should be ground and polished to attain a surface finish of 15 microinches or better. Again, the maintenance of the taper and ovality of the crankpin and crankshaft main journal has to be within the limit recommended by the manufacturer. Generally, the limits are within 0.02 to 0.05 mm, depending on the diameter of the crankpin and main journal. A few years back, it was a monopoly of a few European companies undertaking onsite crankshaft grinding and crankshaft polishing jobs, charging exorbitant prices from the shipping companies and the power plants, who had no option but to get the job of onsite crankshaft grinding and crankshaft polishing done from them.

RA Power Solutions has been extending crankshaft grinding, crankshaft polishing, maintenance, and repair of high-capacity engines for the last forty-five years. Out on our experience, we have developed and manufactured onsite crankshaft grinding and crankshaft polishing machines having a range from 30 mm to 700 mm. The onsite crankshaft grinding machine has brought down the cost of repair of the crankshaft and has broken the monopoly of the European service providers.
