Piston Pin Inspection
- Measure diameter of piston pin. Zero dial indicator to piston pin diameter. Insert dial indicator into piston pin bore to measure piston pin-to-piston clearance. If clearance exceeds specification, install oversize piston pin and recheck clearance. See PISTONS, PINS & RINGS table under ENGINE SPECIFICATIONS.
- Measure difference between piston pin diameter and connecting rod small end diameter. Ensure interference fit between piston and connecting rod is within specification. See PISTONS, PINS & RINGS table under ENGINE SPECIFICATIONS.
