Piston Pins
- Piston pins are available in .002" (.05 mm) oversize from standard diameter. If replacement oversize pins are needed, piston pin hole should be reamed out to correct measurement using reaming tool. Use reamer fitted with pilot guide, take only small cuts at a time.
- Pin fit is correct when pin can be pushed through connecting rod hole with only light thumb pressure (close running fit). Pin should push easily through piston.
