Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Illustration 1 g00974873
Install the upper connecting rod bearing (4) in the connecting rod. The upper connecting rod bearing must be centered in the connecting rod. Lubricate the bearing face with clean engine oil.
Pull the connecting rod into position against the crankshaft.Note: Do not allow the connecting rod to contact the piston cooling jet.
Clean the connecting rod cap (2) and the lower connecting rod bearing (3) . Lubricate the bearing face with clean engine oil.
Install the lower connecting rod bearing (3) in the connecting rod cap (2) . The lower connecting rod bearing must be centered in the connecting rod cap. Lubricate the bearing face with clean engine oil.Note: The connecting rod is a forging. The connecting rod has been hydraulically split in order to separate the connecting rod cap and the connecting rod. This process provides accurately matched surfaces. Do Not mix the connecting rod cap and the connecting rod.Note: Ensure that the etched number on connecting rod bearing cap (2) matches the etched number on the connecting rod (5) . Ensure that the numbers (Y) are on the same side.

Install the connecting rod cap (2) .
Install new setscrews (1) in the connecting rod.Note: Do not reuse the old setscrews in order to secure the connecting rod cap.
Tighten the setscrews evenly to a torque of 18 N m (13 lb ft).
Tighten the setscrews evenly to a torque of 70 N m (52 lb ft).
Use the Tooling (A) to achieve the correct final torque.Note: If the Tooling (A) is not used, place an index mark on each setscrew.
Turn the setscrews for an additional 120 degrees.
Rotate the crankshaft in order to ensure that there is no binding.
Repeat Steps 1 through 11 for the remaining connecting rod bearings.End By:
Install the engine oil pump. Refer to Disassembly and Assembly, "Engine Oil Pump - Install".
Install the engine oil pan. Refer to Disassembly and Assembly, "Engine Oil Pan - Remove and Install".
