Ford Mustang (1999-2004) Service Manual: Piston - Pin to 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 out of specification, install new components as necessary.
Piston -Diameter
1. Measure the piston diameter 90 degrees from the piston pin at the point indicated.
- If out of specification, install new components as necessary.
Piston -to Cylinder Bore Clearance
