16. Timing Chain and Sprocket Removal

Timing Chain and Sprockets Removal

^ Tool Required
- J 22888-20A Crankshaft Gear Puller





Important: Before removing the timing chain, measure the distance between the center of the hole in the bracket and the unworn surface of the timing chain tensioner shoe. The hole accepts a pin that holds the shoe in a retracted position to ease timing chain installation.
If the distance between the center of the hole and the unworn surface of the timing chain tensioner shoe is more than 8 mm (0.314 inch), replace the tensioner, timing chain, and both sprockets.

1. Remove the timing chain tensioner bolts.





Notice: Do not replace only the tensioner or the chain to correct a noise condition caused by the camshaft drive components. When replacing the tensioner or chain to correct a noise condition all of the camshaft drive components must be replaced.

2. Remove the timing chain, the timing chain tensioner, and the camshaft sprocket at the same time.
3. If removing the camshaft, remove the camshaft position sensor.





4. Use the J 22888-20A to remove the crankshaft sprocket.
