Connecting Rod Reconditioning

When the connecting rod is received in our workshop, it is dismantled, cleaned and inspected. The inspector looks for damage, cracks, overheating, and ovality in the big-end bore. The connecting rod is magnaflux tested with a full report for class society approval. The serration is then reconditioned, by spark erosion, not milling!

When performing the serration by spark erosion it is possible to make a small radius at all edges in order to minimize any risk for future cracks in the serration.

The bore is machined to specified diameters and Shot Peening is performed, if required. A final inspection of the Connecting Rod is carried out before it is assembled with new nuts, bolts and small-end bush.

New is not necessarily best!
A Connecting Rod with a wear and damages can in most cases be repaired at a price up to 75% less than buying a new one. It can even improve life cycles compared to new components from the manufacturer – and with even better delivery times.

Availability and fast response are key to our mutual success, and at the same time we can offer to repair parts which often would be stated as non-repairable. Common problems can most likely be repaired in our workshop and along comes always a 24-month liability for shortages and defects.

The PJ Diesel component workshop is located in Rødby, south of Copenhagen, and is specialized in the reconditioning of major engine components. We offer service, repair and maintenance of all types of Connecting Rods. Class inspection is available upon request.

We have a team of factory trained service engineers working around the clock to service our customers.
