Connecting Rod Repair

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.

**Inspection of Crankshaft is in Process**

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:

Connecting rod is subject to chemical cleaning and shot blasting after dismantling.
The big end and small end bore of connecting rod are checked and recorded
Connecting rod is checked for cracks and overheating by MPI or Dye penetrant test.
The serration of the joining face connecting rod bolts are also subject to crack detection.
Center to center distance of big end bore and small end bore is also checked.
Straightness of connecting rod is also checked.

**Inspection after Reconditioning of Connecting Rods**

The connecting rod’s big end and small end are re-machined/bored on the latest design of the boring machine equipped with DRDO. All the connecting rods repaired by us are guaranteed for satisfactory performance and are 100% check for quality.

Metal Stitching | Metal Locking | Repair of Cast Iron by Metal Stitching – RA Power Solutions

When cast-iron or aluminum engine blocks crack, the traditional fix—welding—is often expensive, risky, and destructive. At RA Power Solutions, we specialize in advanced cold repair techniques—metal stitching and metal locking—that restore structural strength without applying heat, requiring machining, or dismantling equipment.

With the improvement in repair technology now, it is possible to repair the crack in cast iron, steel, or aluminium component by metal stitching and metal locking process. The main feature of repair of crack or damaged casting by metal stitching, metal locking, and metal surgery is that process does not require disassembly of the equipment and taking the crack or damaged part to the workshop.

What Are Metal Stitching & Locking?

Metal Stitching is a precise, cold repair method. Technicians drill a series of aligned holes across the crack, insert metal “keys” or studs into a dovetailed pattern, and tighten them so they interlock—effectively sealing the fracture and restoring rigidity.
Metal Locking reinforces the stitching with custom-shaped metal inserts that prevent the crack from spreading further and enhance the repair’s long-term durability

New Casting Inserted for Repair of Engine Block

RA Power Solutions has the team of experience technicians. They can travel to the site with tools and consumables required for metal stitching and metal locking undertake the repair.We repair cracks by metal locking and metal stitching while maintaining the original profile.

Connecting Rod of Yanmar Engine Ready for Inspection Before Reconditioning

FAQs:

1. How do I know when a connecting rod needs reconditioning?

Look out for engine noise, vibration, oil contamination, or routine inspection findings like ovality or taper in rod bores.

2. Can every connecting rod be repaired?

No—if the rod is bent or has significant cracks, especially near the bolts or serrations, replacement is safer than reconditioning.

3. What types of engines can you service?

We support a wide range—including MAN, B&W, Wartsila, MAK, Deutz, Daihatsu, Yanmar, Mitsubishi, Caterpillar, and many others.

4. How much cost savings can I expect?
