Piston Pin Replacement
- With piston and rod assembly removed as previously outlined, remove circlips from piston. Heat piston to approximately 250-300°F and push pin from piston.
- Check piston pin fit in piston. Pin should push fit in piston with piston heated to 250-300°F. Check piston pin and rod clearance. If clearance is more than specified, piston pin and bushing must be replaced.
- Press bushing from connecting rod using a suitable mandrel. Press new bushing in rod making sure oil holes in bushing and connecting rod align. Ream bushing to specified clearance with new piston pin.
- When assembling piston and connecting rod, make sure oil hole at crankshaft end of rod and "F" mark on piston are on the same side. Install piston and rod assembly as previously outlined.
