* EN-48313 - Timing Chain Retention Tool

Removal Procedure

1. Remove the lower intake manifold. Refer to Intake Manifold Replacement Intake Manifold Replacement.

2. Remove the left bank camshaft cover. Refer to Camshaft Cover Replacement - Left Side Camshaft Cover Replacement - Left Side.

3. Remove the camshaft sensors. Refer to Camshaft Position Sensor Replacement - Bank 2 (Left Side) Exhaust Camshaft Position Sensor Replacement - Bank 2 (Left Side) Exhaust and Camshaft Position Sensor Replacement - Bank 2 (Left Side) Intake Camshaft Position Sensor Replacement - Bank 2 (Left Side) Intake.

4. Remove the camshaft position actuator solenoids. Refer to Camshaft Position Actuator Solenoid Valve Solenoid Replacement - Bank 2 (Left Side) Intake Camshaft Position Actuator Solenoid Valve Solenoid Replacement - Bank 2 (Left Side) Intake and Camshaft Position Actuator Solenoid Valve Solenoid Replacement - Bank 2 (Left Side) Exhaust Camshaft Position Actuator Solenoid Valve Solenoid Replacement - Bank 2 (Left Side) Exhaust.

5. Remove the crankshaft balancer. Refer to Crankshaft Balancer Replacement Service and Repair.




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





Caution: Refer to Torque Reaction Against Timing Drive Chain Caution Service Precautions.

Note:

* 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.





Note: Ensure that the tips of the EN-48313 - Timing Chain Retention Tool are fully engaged into the timing chain (3 and 4).

8. Install the EN-48313 - Timing Chain Retention Tool (1 and 2) in order to retain the timing chain.
Firmly tighten the EN-48313 - Timing Chain Retention Tool nuts.





Note: 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 the camshaft position actuators (1-4).

10. Remove the camshaft position actuator bolt.

11. Remove the camshafts. Refer to Camshaft Removal - Left Side 33. Camshaft Removal - Left Side.

Installation Procedure





Note:

* Ensure that the marks on the camshaft position actuator and the timing chain (1-4) 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 - Left Side 100. Camshaft Installation - Left Side.

3. Remove the EN-48313 - Timing Chain Retention Tool.





Caution: Refer to Torque Reaction Against Timing Drive Chain Caution Service Precautions.
