Illustration 1 g00634006 - Install Tooling (A) on the piston.
Note: Ensure that Tooling (A) is installed correctly and that the piston can easily slide from the tool.
Note: The arrow or the "FRONT" mark 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 liner and onto the connecting rod journal.
- Align the tabs on the connecting rod bearings with the tab grooves on the connecting rod cap. Install the connecting rod bearing in the connecting rod cap.
- Lubricate the lower connecting rod bearing with clean engine oil.
