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.

  • 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.

Connecting Rod Reconditioning – RA Power Solutions

The connecting rods of the engine are under tremendous pressure. The connecting rod has to bear the extreme load and stress condition. In most of the cases connecting rods are made out of forging and composition of material is selected to give enough strength to the connecting rod.

The continuous running, stopping, and changing of direction combined with the weight of the piston and rpm of the engine put lot of stress on the connecting rod. This results to the development of various defects in connecting rod like excessive taper and ovality in big end and small end of connecting rod, loss of alignment of connecting rod, etc.

RA Power Solutions Pvt. Ltd. undertakes reconditioning of connecting rods for high-capacity diesel engine of all make MAN-B&W, Sulzer, Wartsila, Mak, Deutz, Pielstick, Mitsubishi, Daihatsu, Yanmar, Bergen, Niigata, Himsen, Allen, Stork, Fiat, MWM, Hanshin, Caterpillar, SKL, Ruston, Paxman, Crepelle, Mirrlees, Alco, ABC, Crepelle, Nohab etc.

Following steps are followed for reconditioning and resizing of connecting rod

  • Connecting rod is checked for parallelism, alignment and taper and ovality in big end and small end.
  • Connecting rods having bend are not recommended for repair as per RA Power Solutions Pvt. Ltd. experience.
  • Crack detection by MPI is done of connecting rod bolt sitting area and bolts. The connecting rod bolts again are under heavy stress all the time and develop hairline cracks. It is recommended to replace connecting rod bolts after certain hours of operation as specified in manual.
  • The connecting rod big end is re-bored to the standard size and tolerances are maintained. In case of connecting rod small end it is recommended to replace the bush and re-bore it maintaining the center distance between the big end bore and small end bore as per the manufacturer’s specifications.
