Connecting Rod
WARNING: This page is about a different car, the 2017 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Two different type of connecting rods have been used on the 6.7L. One type connecting rod has three bumps on the cap end and the other does not; due to weight differences in the rods, engine vibration will result. Special consideration must be given not to mix connecting rods. Only use the same type connecting rod when replacing.
- Inspect the connecting rod for damage and wear. The I-Beam section of the connecting rod cannot have dents or other damage. Damage to this part can cause stress risers which will progress to breakage.
- Measure the connecting rod pin bore (1). The minimum diameter is 40.019 mm (1.575 inch), maximum diameter is 40.042 mm (1.576 inch). If out of limits, replace the connecting rod.
