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

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

We are following procedure for repair of connecting rods:

Connecting rods are thoroughly cleaned by special chemicals to remove oil and dirt.
Connecting rod is checked visually for any signs of overheating which

**Calibration of Connecting Rod in Process**

may be indicated by a “bluish” appearance. In that case, it is recommended to check the hardness and undertake MPI for crack detection on the area which is exposed to the overheating.

Magnetic particle test by qualified technician is undertaken under supervision of senior engineer to check the crack on serration, connecting rod bolt and bolt sitting area and complete connecting rod. No crack whatsoever are accepted on connecting rod.
Connecting rod bolts are checked for elongation; in case of any deviation bolts are replaced.
Connecting rod big end bolt is tightened as per the torque specified by the manufacturer.
Big end bore taper and ovality is checked. The bore is also checked visually for any damage.

**Repair of Connecting Rod is in Process**

The small end bore is also inspected 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.
The small end bush is replaced with new one in case the taper and ovality is on higher side.
Connecting rod is placed on our boring machine equipped with latest generation of DRDO. The straightness of connecting rod is checked.
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.
Boring of big end bore and small end bore is done simultaneously not only to maintain the taper and ovality of big end small bore but to ensure that centre distance of both the bores is maintained.
All the sharp edges are removed after boring operation.
Connecting rod is again subject to dimensional inspection and all the readings are recorded.
While returning the connecting rod, proper packing is ensured.
