Camshaft Position Exhaust Actuator Replacement - LE5 or LE9

Special Tools

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

1. Remove the camshaft cover. Refer to Camshaft Cover Replacement : LE5 or LE9 .
2. Remove the spark plugs. Refer to Spark Plug Replacement .



3. Rotate the crankshaft clockwise and install the EN-48953 locking tool (1).

Caution: Refer to Fastener Caution in the Preface section.

4. Install the camshaft actuator retainer bolts and tighten to 10 N·m (89 lb in).
5. Loosen, but do not remove the exhaust camshaft actuator bolt.
6. Remove the EN-48953 locking tool (1).
7. Clean the timing chain and gears with solvent.

Note: Ensure the timing chain and the camshaft position actuators are marked for proper assembly.

8. Mark the intake and exhaust camshaft actuators and the respective locations on the timing chain.



9. Remove the upper timing chain guide bolts and guide.



10. Remove the timing chain tensioner.




Note: 

•	The camshaft actuators should not rotate during removal or installation.

•	Ensure the tips of the EN-48749 retention tool are fully engaged into the timing chain. The retention tool rod can be used on the rear side of the chain to ensure the teeth from the retention tool are engaged.

11. Install the EN-48749 retention tool (1) to the exhaust side of the timing chain.



12. Remove and discard the exhaust camshaft actuator bolt (2).
13. Remove the exhaust camshaft actuator (3) from the camshaft while also removing the actuator from the timing chain.

Note: 

•	Ensure that the alignment mark made previously on the intake camshaft actuator is still aligned properly with the mark on the timing chain.

•	The exhaust camshaft may need to be rotated clockwise to fully set the camshaft actuator.

1. Install the timing chain onto the exhaust camshaft actuator.
2. Align the exhaust camshaft actuator alignment mark made previously with the timing chain mark and install the actuator onto the camshaft.
3. Install a NEW exhaust camshaft actuator bolt (2) until snug.




Note: Ensure that the alignment mark previously on the exhaust camshaft actuator is still aligned properly with the timing chain. If the mark made previously on the inlet camshaft actuator is not aligned properly, refer to Camshaft Timing Chain, Sprocket, and Tensioner Replacement : LE5 or LE9 .

4. Remove the EN-48749 retention tool (1) from the exhaust side of the timing chain.

Note: Failure to reset the tensioner will allow the tensioner to over extend, limiting the timing chain's life.

5. Reset and install the timing chain tensioner. Refer to Timing Chain Tensioner Replacement : LE5 or LE9 .



6. Install the EN-48953 locking tool (1).
7. Install the camshaft actuator retainer bolts and tighten 10 N·m (89 lb in).
8. Tighten the NEW camshaft actuator bolt to 30 N·m (22 lb ft) plus an additional 100 degrees using the EN-45059 meter .

Note: You must have the EN-48953 locking tool installed to perform this procedure.

9. To release the tensioner apply an anticlockwise rotational torque to the crankshaft balancer bolt of 45 N·m (33 lb ft).



10. Remove the camshaft actuator retainer EN-48953 locking tool (1).



11. Install the upper timing chain guide and bolts and tighten to 10 N·m (89 lb in).
12. Install the camshaft cover. Refer to Camshaft Cover Replacement : LE5 or LE9 .
13. Install the spark plugs. Refer to Spark Plug Replacement .
