Piston Pins
NOTE:
Piston and pin are a matched set. Keep piston, pin, rings and rod together for each cylinder.
- Check fit between piston and pin by trying to move piston back and forth on piston pin. If movement is felt, replace piston and pin.
- To remove pin, warm piston and rod assembly to about 70°F (20°C). Press out pin using Piston Pin Installer/Remover (09221-25017). DO NOT damage piston during removal.
- Check pin and piston pin hole for signs of gouging or excessive wear. To assemble piston and rod, reheat piston to 70°F (20°C). Align cavity on piston with straightedge on connecting rod. See Figure.
- Hold piston and rod in proper alignment. Coat pin with oil and insert into piston using piston pin installer/remover. Ensure there is no movement of piston on pin.
