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 liner with clean engine oil.
- 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 cap in the connecting rod. Ensure that the locating tab is correctly installed in the connecting rod.
- Lubricate the bearing for the upper connecting rod journal with clean engine oil.
- Align the piston rings on the piston so that the distance between the gaps is 120 degrees.
- Install Tooling (B) on the piston.
Note: Ensure that Tooling (B) is installed correctly and that the piston can easily slide out of the Tooling.
Note: The arrow or "FRONT" Mark that is on the top of the piston must be toward the front of the engine.

- Use the following procedure with serrated connecting rods and flat connecting rods:
- If the connecting rod cap is held in position with bolts and nuts, tighten the nuts to a torque of 125 N·m (92 lb ft).
- If the connecting rod cap is held in position with bolts, tighten the bolts to a torque of 155 N·m (114 lb ft).
- Use the following procedure with hydraulically fractured connecting rods:
- Tighten the bolts to a torque of 70 N·m (52 lb ft).
Note: Do not reuse the bolts. New bolts should be used.
- Tighten the bolts for an additional 120 degrees.
- Rotate the crankshaft in order to ensure that there is no binding.
- Use Tooling (C) in order to check the height of the piston above the cylinder block. Refer to Testing and Adjusting, "Piston Height - Inspect".
End By:
