Second-Hand Connecting Rods | Repair of Connecting Rods | Reconditioning of Connecting Rods – RA Power Solutions

Connecting rods of high capacity, main and auxiliary engines are repaired by RA Power Solutions. Connecting rods during the operation of the engine are heavily stressed, transmitting power generated in the combustion chamber to the crankshaft. It is important that periodically or at the time of general overhauling, the condition of the connecting rod is checked and either it is replaced or connecting rod is reconditioned.
