Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Thoroughly clean all of the components.
Lubricate the piston and the cylinder bore with clean engine oil. Note: The piston and connecting rod are matched to a specific cylinder. Ensure that the connecting rod and pistons are installed in the correct cylinder.
Rotate the crankshaft until the connecting rod journal is at the bottom center. Lubricate the connecting rod journal with clean engine oil.
Install the upper connecting rod bearing in the connecting rod. The upper connecting rod bearing must be centered in the connecting rod. Lubricate the upper connecting rod bearing with clean engine oil.
Install Tooling (B) on the piston. Note: Ensure that Tooling (B) is installed correctly and that the piston can easily slide from the tool.Note: The arrow that is on the top of the piston must be toward the front of the engine.
Push the piston and the connecting rod assembly into the cylinder bore and onto the connecting rod journal.
Install the lower connecting rod bearing in the connecting rod cap. The lower connecting rod bearing must be centered in the connecting rod cap. Lubricate the lower connecting rod bearing 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.

Typical example
Install connecting rod cap (2).
Install new bolts (1) in the connecting rod. Tighten bolts (1) evenly to a torque of 40 N m (30 lb ft). Note: Do Not reuse the old bolts in order to secure the connecting rod cap.
Use Tooling (C) to achieve the correct final torque. Note: If Tooling (C) is not used, place an index mark on each bolt.
Turn bolts (1) for an additional 120 degrees in a clockwise direction.
Rotate the crankshaft in order to ensure that there is no binding.
Repeat Steps 2 through 12 in order to install the remaining pistons and connecting rods.
Refer to Testing and Adjusting, "Piston Height - Inspect" for the correct procedure on checking the height of the piston above the cylinder block. End By:
Install the piston cooling jets. Refer to Disassembly and Assembly, "Piston Cooling Jets - Remove and Install".
Install the engine oil pump. Refer to Disassembly and Assembly, "Engine Oil Pump - Install".
Install the cylinder head. Refer to Disassembly and Assembly, "Cylinder Head - Install".
