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.

RA Power Solutions has four decades of experience in reconditioning of connecting rods up to the bore size of 500 mm. Following process is adopted for successful reconditioning of connecting rods:

I) Connecting rod is subject to chemical cleaning and shot blasting after dismantling.

II) The big end and small end bore of connecting rod are checked and recorded

III) Connecting rod is checked for cracks and overheating by MPI or Dye penetrant test.

IV) The serration of the joining face connecting rod bolts are also subject to crack detection.

V) Center to center distance of big end bore and small end bore is also checked.

VI) Straightness of connecting rod is also checked.
