Removal Procedure

1. Remove the camshaft cover. Refer to Camshaft Cover Replacement (LUK) Service and RepairCamshaft Cover Replacement (LEA) Service and Repair.

2. Remove the spark plugs. Refer to Spark Plug Replacement Service and Repair.





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

Caution:
Refer to Fastener Caution Fastener Caution.

4. Install the camshaft actuator retainer bolts and tighten to 10 Nm (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 (1) and guide (2).





10. Remove the timing chain tensioner (1).





Note:

* The camshaft actuators should not rotate during the 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 back 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.

Installation Procedure





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 intake camshaft actuator is not aligned properly, refer to Camshaft Timing Chain, Sprocket, and Tensioner Replacement Service and Repair.

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 life.

5. Reset and install the timing chain tensioner. Refer to Timing Chain Tensioner Replacement Service and Repair.





6. Install the EN-48953 - locking tool(1).

7. Install the camshaft actuator retainer bolts and tighten 10 Nm (89 lb in).

8. Tighten the NEW camshaft actuator bolt to 30 Nm (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 a counterclockwise rotational torque to the crankshaft balancer bolt of 45 Nm (33 lb ft).





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





11. Install the upper timing chain guide (2) and bolts (1) and tighten to 10 Nm (89 lb in).

12. Install the camshaft cover. Refer to Camshaft Cover Replacement (LUK) Service and RepairCamshaft Cover Replacement (LEA) Service and Repair.

13. Install the spark plugs. Refer to Spark Plug Replacement Service and Repair.
