Camshaft Replacement - Right Side

Camshaft Replacement - Right Side


Tools Required
* EN 46108 Timing Chain Retention Tool
* EN 46111 Crankshaft Rotation Socket



Removal Procedure

1. Remove the lower intake manifold. Refer to Lower Intake Manifold Replacement (Service and Repair) .
2. Remove the camshaft cover. Refer to Camshaft Cover Replacement - Right Side (Camshaft Cover Replacement - Right Side) .
3. Remove the camshaft sensors. Refer to Camshaft Position Sensor Replacement - Bank 1 (Right Side) Exhaust and Camshaft Position Sensor Replacement - Bank 1 (Right Side) Intake .
4. Remove the intake camshaft position actuator solenoid. Refer to Camshaft Position Actuator Solenoid Valve Solenoid Replacement - Bank 1 (Right Side) Intake .
5. Remove the crankshaft balancer. Refer to Crankshaft Balancer Removal (Overhaul) .




6. Rotate the crankshaft with the EN 46111 until the camshafts are in a neutral (low tension) position. The camshaft flats will be parallel with the camshaft cover rail (1).





Notice: Refer to Torque Reaction Against Timing Drive Chain Notice .


Important:
* Use an open-end wrench at the camshaft hex to prevent camshaft/engine rotation.

* DO NOT remove the camshaft position actuator bolt at this time.



7. Loosen the camshaft position actuator bolt.

Important: Ensure that the tips of the EN 46108 are fully engaged into the timing chain (3 and 4).






8. Install the EN 46108 (1 and 2) in order to retain the timing chain.
Firmly tighten the EN 46108 nuts.





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


9. Mark the timing chain and the respective locations on camshaft position actuators (15-18).
10. Remove the camshaft position actuator bolt.
11. Remove the camshaft bearing caps and the camshaft. Refer to Camshaft Removal - Right Side (Overhaul) .



Installation Procedure






Important:
* Ensure that the marks on the camshaft position actuators and the timing chain (15-18) are aligned.

* DO NOT tighten the camshaft position actuator bolt at this time.



1. Locate the camshafts to the cylinder head and assemble the camshaft actuators to the camshafts.
2. Install the camshafts and the camshaft bearing caps. Refer to Camshaft Installation - Right Side (Overhaul) .
3. Remove the EN 46108 .
4. Install the crankshaft balancer. Refer to Crankshaft Balancer Installation (Overhaul) .
