- Position piston on support. See Fig 1. Press piston pin from piston. Discard pin. Piston pin cannot be reused after removal. Inspect piston pin bore in connecting rod for nicks and burrs, and remove as necessary. Clean and dry piston pin bore and NEW piston pin.
- Clean piston pin bore and replacement piston pin. Piston and piston pin must be at room temperature when measuring fit. Piston pin should fall through piston at room temperature. If pin jams in pin bore, replace piston.
- Ensure arrow on piston crown is pointing up. Insert piston pin through piston pin bore and into connecting rod pin bore. Assemble connecting rod and piston so oil squirt hole faces camshaft and arrow on piston points to front of engine when installed.
- Press pin through rod and piston until pilot indexes with mark on support. Pin should be centered in rod. Piston pin installation requires approximately 2000 lbs. (900 kg) of force. Replace connecting rod if noticeably less force is required, or if rod moves on pin.
