Crankshaft damage is one of the most critical issues faced by marine, power plant, and industrial engines. Problems such as bearing seizure, scoring, taper, ovality, or journal damage can lead to severe engine failure if not addressed promptly and accurately. Crankshaft grinding and repair by experienced technicians is the most effective solution to restore engine reliability and performance.
RA Power Solutions specialises in onsite crankshaft grinding and repair, carried out by highly skilled technicians using advanced portable grinding and polishing machines. Our repair methodology minimises downtime and eliminates the need for complete engine dismantling.
Onsite Crankshaft Grinding and Repair Services
The crankshaft grinding machine used to undertake crankshaft repair is of the latest design, having minimal vibrations. This facilitates our technicians to undertake crankshaft repair even while the vessel is sailing. The tolerance after crankshaft grinding and crankshaft repair is maintained within 10 to 20 microns in terms of taper and ovality.
The repair of the crankshaft and overhauling of the engine while sailing the vessel between two ports results in considerable savings to the ship owners, as there is no need to hold the vessel at port or anchorage.
