Piston & Rod Assembly
WARNING: This page is about a different car, the 1995 Jeep Wrangler and 1994 Jeep Wrangler. However, it is still accessible from the selected car via links, so may be relevant.
- Note locations of arrow on piston crown and oil squirt hole in connecting rod. Position piston and rod assembly 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 or burrs and remove as necessary.
- 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.
- Position piston on support so that arrow on piston crown will point to front of engine and connecting squirt hole will face camshaft when installed. Insert piston pin through piston pin bore and into connecting rod pin bore.
- Press pin through rod and piston until pilot aligns 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.
