Piston Pin Bore Diameter

1. WARNING: Cover the end of the pin bore with a hand or shop rag when removing the retainer ring, since it has a tendency to spring out. Wear eye protection.

Note: Piston and piston pins are a matched set and should not be interchanged.








Measure the piston pin bore diameter in two directions on each side. Verify the diameter is within specification.
- If it is out of specification, install new components as necessary.
