Product Features
- Complete timing chain kit includes chain, cam sprocket, crank sprocket, and tensioner for a full replacement.
- Inverted tooth (silent) chain design reduces noise and vibration during operation.
- Pre-stressed chain reduces stretch and increases chain life. Hardened chain pins increase durability.
- Heat-treated gear sprocket teeth reduce wear and increase resistance to corrosion.
- Designed specifically for GM 2.2L LN2 OHV four-cylinder engines.
- OE-grade materials and manufacturing standards ensure long service life.
Installation Notes
- Verify timing marks on both sprockets are properly aligned before installation. Marks should align with No. 1 cylinder at TDC on compression stroke.
- Inspect timing chain tensioner (9115) for proper function – replace if worn or damaged.
- Check crankshaft and camshaft keyways for damage before installing new sprockets.
- Torque camshaft sprocket bolt to 77 ft. lbs. (105 Nm).
- Torque tensioner bolts to 18 ft. lbs. (24 Nm).
- After installation, rotate engine manually to verify proper timing alignment.
- Cloyes recommends replacing tensioner, sprockets, and guides when the chain is replaced, as these components play a vital role in system stability and accurate timing.
