Use Tooling (A) to rotate the crankshaft until the connecting rod is at the bottom center.
Inspect the connecting rod and connecting rod cap for the proper identification mark. The connecting rod and the connecting rod cap should have an etched number on the side. The number should match the cylinder number. Mark the connecting rod and the connecting rod cap, if necessary.Note: Do not stamp the connecting rod assembly. Stamping or punching the connecting rod assembly could cause the connecting rod to fracture.
Remove bolts (1) and connecting rod bearing cap (2) from the connecting rod.
Remove the lower half of the connecting rod bearing from the connecting rod bearing cap.
Push the connecting rod away from the crankshaft. Remove the upper half of the connecting rod bearing from the connecting rod.Installation Procedure
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: Install the connecting rod bearings dry when clearance checks are performed. Refer to Disassembly and Assembly, "Bearing Clearance - Check". Apply clean engine oil on the connecting rod bearings for final assembly.

Use Tooling (A) to rotate the crankshaft until the connecting rod journal is at the bottom center.
Install a new lower half connecting rod bearing (3) in connecting rod bearing cap (2).Note: Ensure that bearing locking tab (4) is located in the notch of the connecting rod bearing cap.
Install a new upper half connecting rod bearing in the connecting rod.Note: Ensure that the bearing locking tab is located in the notch of the connecting rod.
Pull the connecting rod onto the crankshaft.

Position connecting rod bearing cap (2) on the connecting rod.Note: Ensure that the number on the side of the connecting rod bearing cap is on the same side as the number on the connecting rod. The bearing tabs of the connecting rod bearing cap and the connecting rod are located on the side of the piston cooling jet.
Lubricate the threads of bolts (1) with clean engine oil. Install the bolts.
Tighten bolts (1), as follows:
Tighten Bolt (A) and Bolt (C) to a torque of 70 4 N m (52 3 lb ft).
Tighten Bolt (B) and Bolt (D) to a torque of 70 4 N m (52 3 lb ft).
Turn Bolt (B) and Bolt (D) for an additional 60 5 degrees (1/6 turn).Note: If Tooling (B) is not used, place an index mark on each bolt.
Tighten Bolt (A) and Bolt (C) again to a torque of 70 4 N m (52 3 lb ft).
Tighten Bolt (A) and Bolt (C) for an additional 60 5 degrees (1/6 turn).Note: If Tooling (B) is not used, place an index mark on each bolt.
Rotate the crankshaft in order to ensure that the crankshaft turns freely.End By:
Install the engine oil pump.
