Timing Chain and Tensioner Removal - LE5 or LE9

Special Tools

EN-48953 Camshaft Actuator Locking Tool

For equivalent regional tools, refer to Special Tools : LE5 or LE9 .

1. Rotate the crankshaft to install EN-48953 locking tool (1).

Note: Marking the chain and actuators is crucial to procedures operation. The camshaft actuator and timing chain must have oil removed from the surface prior to marking both actuators and chain.

2. Install EN-48953 locking tool onto the cylinder head and tighten to 10 N·m (89 lb in). If the intake camshaft actuator is moving independently of the cam and is not locked, rotate the intake camshaft anticlockwise and the tool will hold the actuator, locking the actuator to the cam.
3. Loosen the intake camshaft actuator bolt.
4. Loosen the exhaust camshaft actuator bolt.
5. Remove EN-48953 locking tool.



6. Remove the upper timing chain guide bolts.
7. Remove the upper timing chain guide (1).




Note: The timing chain tensioner must be removed to unload chain tension before the timing chain is removed.

8. Remove the timing chain tensioner plunger (1).



9. Locate hex on the exhaust camshaft and hold with a wrench (2).
10. Remove the exhaust camshaft bolt and the exhaust camshaft actuator (1). Discard the bolt.



11. Remove the adjustable timing chain guide bolt.
12. Remove the adjustable timing chain guide (1).



13. Remove the plug (1) to gain access to the fixed timing chain guide bolt.



14. Remove the fixed timing chain guide bolts.
15. Remove the fixed timing chain guide (1).



16. Locate hex on the intake camshaft and hold with a wrench.
17. Remove the intake camshaft actuator bolt, the intake camshaft actuator (1) and the timing chain (2) through the top of the cylinder head. Discard the bolt.




Note: 

•	The number 3 exhaust valves are open.

•	Note the position and direction of the camshafts before removal. Mark the cylinder head in relation to the locking notches before component removal.

18. Mark the cylinder head where the exhaust camshaft actuator locking notch (1) and intake camshaft locking notch (2) are lined up with the cylinder head.



19. Remove the crankshaft sprocket (2) and friction washers (1), if equipped.



20. Remove the timing chain oil nozzle bolt.
21. Remove the timing chain oil nozzle (1).
