Connecting Rod

CONNECTING ROD










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 maximum diameter is 40.042 mm (1.5765 inch), minimum diameter is 40.019 mm (1.5756 inch). If out of limits, replace the connecting rod.

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.
