38. Piston and Connecting Rod Assemble

Piston and Connecting Rod Assemble





1. Notice: Install the piston pin retainers correctly in the retaining groove during assembly in order to avoid engine damage.

Install the retaining clip. The clip should be seated in the groove of the pin bore.





2. Lubricate the pin and pin bore with clean engine oil.
3. Install the piston pin to the piston and connecting rod.
4. Install the retaining clip. The clip should be seated in the groove of the pin bore. Ensure the pin moves freely within the piston pin bore.





5. Notice: Use a piston ring expander to install the piston rings. The rings may be damaged if expanded more than necessary.

Using piston ring pliers, install the piston rings onto the piston.





6. Install the lower oil control piston ring spacer onto the piston.





7. Install the lower oil control piston ring onto the piston (1).





8. Install the upper oil control piston ring onto the piston (1).





9. Position the oil control piston ring end gaps a minimum of 90 degrees apart (1, 2, 3).





10. Install the lower compression piston ring onto the piston. The mark (1) on the side of the piston ring should face the top of the piston.





11. Install the upper compression piston ring onto the piston. The mark (1) on the side of the piston ring should face the top of the piston.
12. Position the compression ring end gaps 120 degrees apart.





13. Install the connecting rod bearings (118) to the rod (119) and cap (117).
