Repair of Connecting Rod for High Capacity Engine – RA Power Solutions

RA Power Solutions has undertaken reconditioning and repair of connecting rods, mainly of high-capacity engines for the last 4 decades of Wartsila, Caterpillar Engine, MAK, MAN, Mitsubishi, Yanmar, Pielstick, Deutz, etc.

We are following procedure for repair of connecting rods:

We thoroughly clean the connecting rods with special chemicals to remove oil and dirt.
We visually check the connecting rod for any signs of overheating, which may appear as a “bluish” discoloration. In such cases, we check the hardness and perform MPI to detect cracks in the overheated area.

Calibration of Connecting Rod is in Process

A qualified technician performs the magnetic particle test under the supervision of a senior engineer. They check the serration, connecting rod bolt, bolt seating area, and the complete connecting rod for cracks. We do not accept any connecting rod with cracks.
We check the connecting rod bolts for elongation. If we find any deviation, we replace the bolts.
We tighten the connecting rod big end bolt according to the torque specified by the manufacturer.
Check the big end bore for taper and ovality. We also look at the bore to see whether it is damaged.

We inspect the small end bore for taper, ovality, or any visual damage.
Connecting rod is subject to shot blasting.
The first step for repair is to lap the serrations to the minimum, in order to bring the bore size to minus with enough allowance for internal grinding. For this special purpose machine is used.
We replace the small end bush with a new one if the taper or ovality is on the higher side.
We place the connecting rod on our boring machine equipped with the latest generation of DRDO. We then check the straightness of the connecting rod.
We do not recommend use of any connecting rod which has lost its alignment. No deviation is accepted and it is not recommended to straighten the connecting rod.
We bore the big end and small end simultaneously. This process not only maintains the taper and ovality of both bores but also ensures the center distance between them is accurate.
All the sharp edges are removed after boring operation.
We again perform a dimensional inspection of the connecting rod. We record all the readings.
While returning the connecting rod, proper packing is ensured.

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

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.
