• Lubricate the bolts (A) with clean engine oil.
• Use a suitable tool (B) to measure the inside diameter within a 20-degree arc from each side of the parting line.
• Measure the inside diameter at 90 degrees from the parting line.

  Standard

  : Refer to CONNECTING ROD .

  Step 1	: 40 N.m (4.1 kg-m, 30 ft-lb)
  Step 2	: 40 N.m (4.1 kg-m, 30 ft-lb)
  Step 3	: Tighten 60°

  CAUTION:

  • To avoid possible damage to the connecting rod, use a vice with brass jaws to hold the connecting rod.
  • To avoid engine damage, ensure the number on the connecting rod and connecting rod cap must match exactly. Connecting rods and connecting rod caps are not interchangeable.
  • If replacing one or more of the connecting rods, check the part number of the new connecting rod compared to the currently installed connecting rods. If the new part number does not match the old part number, replace all of the connecting rods with the latest part number. Do not mix connecting rod part numbers or engine damage could result.
  NOTE: If the measurements are out of specification, try a new set of connecting rod bearings and measure again.
