    NOTE :
    • Apply new engine oil to the bolt threads and flanges.

  1. Remove the connecting rod cap and the connecting rod bearing half, and measure the widest part of the plastigage.

Standard (New): 0.024-0.042 mm (0.00094-0.00165 in)

Service Limit: 0.055 mm (0.00217 in)

  1. If the plastigage measures too wide or too narrow, remove the upper half of the connecting rod bearing.

    Install a new, complete connecting rod bearing with the same color code, and recheck the clearance. Do not file, shim, or scrape the connecting rod bearings or the connecting rod caps to adjust clearance.

  2. If the plastigage shows the clearance is still incorrect, try the next larger or smaller connecting rod bearing (the color listed above or below that one), and check the clearance again. If the proper clearance cannot be obtained by using the appropriate larger or smaller connecting rod bearings, replace the crankshaft and start over.

  1. Inspect each connecting rod for cracks and heat damage
  2. Numbers have been stamped on the side of each connecting rod as a code for the size of the big end. Use them, and the letters stamped on the crankshaft (codes for rod journal size), to choose the correct connecting rod bearings.
    NOTE :
    • If the codes are indecipherable because of an accumulation of dirt and dust, do not scrub them with a wire brush or scraper. Clean them only with solvent or detergent.
    • Each connecting rod falls into one of four tolerance ranges (from 0 to 0.024 mm (0.00095 in), in 0.006 mm (0.00024 in) increments) depending on the size of its big end bore. It is then stamped with a number (1, 2, 3, or 4) indicating the range. You may find any combination of 1, 2, 3, or 4 in any engine.

Big End Bore Size: 48.0 mm (1.890 in)

  1. Use the big end bore codes and the connecting rod journal codes to select appropriate replacement connecting rod bearings from the following table.
    NOTE:
    • Color code is on the edge of the bearing.
    • When using bearing halves of different colors, it does not matter which color is used in the top or bottom.

8. All Removed Parts - Install

  1. Install the parts in the reverse order of removal.
    NOTE:
    Inspect the diameter of each connecting rod bolt when you install the connecting rod caps.
