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.

Why Reconditioning Matters

Connecting rods face immense stresses—from piston movement and combustion forces to high RPMs. Over time, this leads to:

Taper and ovality in both big and small end bores
Misalignment and bent structures
Fatigue damage to serrations, bolts, or bushes

We do not recommend repairing a connecting rod if we find any loss of alignment or cracks. RA Power Solutions guarantees the satisfactory performance of every connecting rod we repair. We issue a calibration certificate for each connecting rod after repair.

Connecting Rod Reconditioning – RA Power Solutions

Engines are the most important parts of heavy-duty industrial machinery, ships, and power plants. The connecting rod is one of the most important parts of an engine. It is very important for moving the combustion force from the piston to the crankshaft. Over time, these rods are put under a lot of stress, fatigue, and heat, which causes them to wear out and possibly break.

Connecting Rod Assembled with Piston After Repair

Rather than replacing connecting rods — which can be expensive and time-consuming — connecting rod reconditioning offers a cost-effective and reliable solution.

At RA Power Solutions, we offer world-class reconditioning services that restore the connecting rod to its original specifications and performance levels.

What Makes Reconditioning Necessary?

During engine operation, the connecting rods face:

High mechanical stress from piston motion
Thermal expansion and contraction
Wear and tear at the small and big end bearings
Cracks or distortion due to oil starvation or overloading

If these problems aren’t fixed, they could cause serious engine damage, such as a crankshaft failure, a piston seizure, or even a complete engine breakdown. That’s why it’s important to recondition things on time to avoid expensive repairs or replacements.

Detailed Reconditioning Process at RA Power Solutions

1. Initial Cleaning and Visual Inspection

Onsite connecting rod repair are cleaned and inspected for any visible signs of cracks, scoring, discoloration, or deformation.

2. Dimensional Analysis

We check for:

Ovality or taper in the big and small ends
Rod length
Bend and twist
Bore misalignment

All measurements are compared with OEM tolerances.

3. Crack Detection

Using Non-Destructive Testing (NDT) methods like Magnetic Particle Inspection (MPI), we detect micro-cracks or structural flaws.

4. Big End and Small End Machining

If the big and small end bores are not round, we re-machine or hone them. If the bush on the tiny end is worn out, it is taken out and replaced with a new one that is the right size.

5. Replacement of Worn Components

We replace connecting rod bolts, nuts, and bushings using certified OEM or equivalent parts to ensure integrity under high load.

5. Straightening and Alignment

Using jigs and hydraulic presses, we realign the rod to original specifications, correcting any bend or twist developed during operation.

6. Final Inspection and Quality Control

Every reconditioned rod is tested for:

Dimensional accuracy
Surface finish
Bolt torque
Structural integrity

Benefits of Choosing RA Power Solutions for Reconditioning

Cost Saving: Reconditioning is 60–70% cheaper than replacement.
OEM Precision: We restore parts to manufacturer specs.
Rapid Turnaround: Save time, especially for critical engines.
On Site Service: No disassembly or transport delays.
Experienced Technicians: 45+ years in engine component repair.
Sustainable Choice: Minimizes industrial waste and promotes part reuse.

Connecting Rod Inspection – A Critical Step in Engine Overhaul By RA Power Solutions

The connecting rod is an important component of engine operation. It connects the piston to the crankshaft, converting the piston’s linear action into rotational motion. Over time and with continuous engine use, the connecting rod experiences high amounts of tension and wear. This makes routine inspection and maintenance of the connecting rod essential to ensure engine reliability and performance.

Second Hand Connecting Rod of CAT Engine

At RA Power Solutions, we specialize in precision inspection and repair of connecting rods for marine engines, power plants, and industrial diesel engines.

Why is connecting rod inspection important?

A damaged or worn-out connecting rod can lead to serious engine problems such as:

Excessive vibration
Piston seizure
Crankshaft damage
Catastrophic engine failure

To avoid these issues, thorough inspection and repair should be part of every engine overhaul and maintenance schedule.

Our Inspection Process Includes:

1. Visual Inspection:

We look for visible cracks, discoloration due to overheating, and wear patterns.

2. Dimensional Check:

Using micrometers, bore gauges, and other precision tools, we check:
Big end bore diameter
Small end bore diameter
Overall length
Parallelism and twist

3. Crack Detection (NDT Testing):

We use Magnetic Particle Inspection (MPI) or Ultrasonic Testing (UT) to detect internal or surface-level cracks invisible to the naked eye.

4. Hardness Testing:

This helps determine whether the connecting rod material is still within acceptable strength limits after long-term usage.

5. Bolt and Bush Inspection:

We thoroughly inspect or replace the connecting rod bolts and bushes, which are often prone to fatigue and wear.

Industries We Serve

We serve a diverse client base in Asia, Africa, the Middle East, and Latin America, including marine, power generating, mining, cement, and heavy engineering industries.

FAQs:

1. What is the connecting rod?

A connecting rod, sometimes known as a ‘con rod’, is a piston engine component that joins the piston to the crankshaft. The connecting rod, along with the crank, turns the piston’s reciprocating action into the rotation of the crankshaft.

2. What type of connecting rod is used in auxiliary engine?

The most frequent type of connecting rod used in the ship’s auxiliary engine is the oblique or cross-cut connecting rod, which is composed of two pieces.

3. How are connecting rods made?

The rods are made of drop-forged, heat-treated steel, which provides the necessary strength. Each rod end is drilled, with the smaller top bore connecting to the piston pin (wrist pin) in the piston. The rod’s big bore end is split in half and bolted so that it can be linked to the crankshaft.
