RA Power Solutions is having experience of more than 44 years in the field of extending Crankshaft and Cylindrical Shaft repair services all over the world. We also design, manufacture and supply In-Situ Crankshaft and cylindrical shaft repair machines up to 700 MM diameter. The main advantage of In-Situ Crankshaft/Cylindrical Shaft repair machine is that there is no requirement for removal of Crankshaft, Intermediate shaft, Pump Shaft, or any type of Cylindrical Shaft from the casing. The grinding and repairs of damage shaft is possible On-Site. Crankshaft Repair & Crankshaft Grinding by In-Situ Crankshaft Grinding Machine   Crankshaft Repair does not require the crankshaft to be removed from entablature. In the recent past due to seizure of bearing or development of taper, ovality, or loss of alignment of 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 a lightweight, vibration-free crankshaft grinding equipment facilitates grinding of crankshaft, crank pin, and crank main journal on the spot while the crankshaft is assembled in the engine block. There is no necessity of even decoupling the alternator and other accessories from the diesel engine. Training In Situ Crankshaft Grinding Machine   We offer training to customer technicians in their workshop. The technicians should have basic knowledge and experience of handling common instruments like micrometer, bore gauge, and vernier caliper. The following areas are covered during the training of working on crankshaft grinding machine.

Wartsila 8L20 Auxiliary engine met with a serious accident, the damage of crankshaft was reported. RA Power Solutions team of two technicians along with onsite crankshaft grinding machine boarded the vessel at Lome Port, Togo. This was possible as all our technicians have valid Passport/Seaman Book/ USA VISA. We have a team of trained technicians available 24/7 hrs. Inspection of the crankshaft of Wartsila 8L20 and Observation On Initial inspection of the crankshaft it was found that the crankpin number #05 was damaged. On further investigation our technicians were surprised to note that the crankpin having standard diameter of 180 MM was already undersized by 2.00 MM and this job was done by a company based in Greece. The excessive taper was observed on the crankpin and no radius fillet profile was made by the crankshaft repair company. Due to the taper in the crankpin number #05 of the Wartsila 8L20 crankshaft, the connecting rod was not moving freely and the bearing was developing line marks. It was a challenging job for RA Power Solutions technicians to rectify the taper, which was developed due to application of wrong equipment and process by a company based in Greece. Action Taken By RA Power Solutions to Successfully Repair Wartsila 8L20 Crankshaft and To Save it from Rejection With our experience of more than 44 Years in repair of the crankshaft, latest design of equipment, and experienced technicians, we were able to successfully repair the crankshaft by under-sizing the crank pin and maintaining the final size of 177.00 MM. The crank pin was undersized by 3.0 mm. The radius fillet profile of both the sides was prepared and maintained, as per the Wartsila 8L20 specifications stipulated in the maintenance manual. The engine was commissioned in presence of our technicians and performance was found satisfactory.
