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.
