Reconditioning of Connecting Rods – Precision Engineering by RA Power Solutions

RA Power Solutions offers advanced connecting rod reconditioning services for marine and industrial engines, ensuring extended service life and OEM-level performance. Our reconditioning process is carried out using state-of-the-art equipment and is compliant with international standards and class certifications.

Step-by-Step Reconditioning Process:

• Shot Blasting:

Used connecting rods are shot blasted to remove carbon deposits, rust, and surface impurities, preparing them for inspection.

• Thorough Cleaning:

Each rod is cleaned using industrial-grade solutions to ensure it is completely free from oil, dirt, and other contaminants.

• Crack Detection—

Magnetic Particle Inspection (MPI): Magnetic Particle Testing is performed to detect surface and sub-surface cracks, ensuring structural integrity before further processing.

• Dimensional Inspection:

Big end and small end bore diameters are measured for taper, ovality, and alignment under specified torque values, using precision gauges as per OEM specifications.

• Straightness Check on DRDO Machine:

Rods are checked for bend or twist using DRDO-calibrated fixtures. Misalignment can lead to oil clearance issues and potential engine failure.

• Overheating & Visual Analysis:

We conduct a visual inspection to detect signs of overheating or discoloration, which may indicate a loss of metallurgical strength.

• Serration Repair:

Serrations are remachined or lapped to restore the perfect locking between the cap and the rod body.

• Resizing of Big End and Small End:

Both ends are resized and honed to OEM tolerances, ensuring perfect fitment of bearings and gudgeon pins.

• Quality Assurance:

All reconditioned connecting rods undergo stringent quality checks and are certified by leading classification societies such as Lloyd’s Register, DNV (Det Norske Veritas), and Indian Register of Shipping (IRS).

Full dimensional and inspection reports are provided for client transparency and class approvals.

We recondition connecting rods for all leading engine brands: Wartsila, MAN, MAK, Sulzer, Daihatsu, Yanmar, SKL, Deutz, and more.
