    IMPORTANT:
    • Each connecting rod falls into 1 of 4 tolerance ranges from 0.0-0.024 mm (0.0-0.0009 in) in 0.006 mm (0.0002 in) increments depending on the inside diameter (I.D.) size of the big end bore. The connecting rod is then stamped with a number or bar indicating the range. It may be common for the connecting rods on the engine assembly to be of a different I.D. size range and stamping.
    • Numbers or bars have been stamped on the side of each connecting rod (1) as a code for the I.D. size of the journal end. Use the connecting rod and crankshaft markings to choose the correct size bearings. If the codes are not legible due to dirt or debris, do not scrub with a wire brush or scraper. Clean them only with solvent or detergent.
  1. Locate the journal bore diameter marking (1) on the side of the connecting rod.
