- Align the piston pin bore with the connecting rod pin bore.
- Slide the piston pin (4) into the piston and the connecting rod (3).
- Install new piston pin retainers (1) by working the retainers into their grooves until a positive lock is heard and felt.
Important: New piston pin retainers must be used. Never reuse the piston pin retainers.
- Ensure that the piston pin retainers are fully seated in their grooves.
- Repeat these procedures for the remaining pistons.
