Camshaft Position Actuator Replacement - Bank 1 (Right Side) Exhaust

Camshaft Position Actuator Replacement - Bank 1 (Right Side) Exhaust


Special Tools

EN 48313 Timing Chain Retention Tool

For equivalent regional tools, refer to Special Tools .

Removal Procedure


1. Remove the right camshaft cover. Refer to Camshaft Cover Replacement - Right Side .


2. Remove the right intake and exhaust camshaft position sensors. Refer to Camshaft Position Sensor Replacement - Bank 1 (Right Side) Intake and Camshaft Position Sensor Replacement - Bank 1 (Right Side) Exhaust .

3. Remove the right intake and exhaust camshaft position actuator solenoids. Refer to Camshaft Position Actuator Solenoid Valve Solenoid Replacement - Bank 1 (Right Side) Intake and Camshaft Position Actuator Solenoid Valve Solenoid Replacement - Bank 1 (Right Side) Exhaust .

4.
Note

Rotate the crankshaft balancer fastener in a clockwise direction ONLY.


Rotate the crankshaft using the crankshaft balancer fastener until the camshafts are in a neutral (low tension) position. The camshafts will be parallel with the camshaft cover rail (1).

5.
Note

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


Use a paint stick to create an alignment mark (16) on one of the timing chain links and the adjacent tooth on the exhaust camshaft position actuator (15).


6. Use a paint stick to create an alignment mark (17) on one of the timing chain links and the adjacent tooth on the intake camshaft position actuator (18).

7. Refer to Torque Reaction Against Timing Drive Chain Caution .

Use an open end wrench on the hex cast into the intake and exhaust camshafts and rotate the camshafts toward each other in order to create slack in the chain between the actuators.

8. Unscrew the EN-48313 timing chain retention tool so that the legs of the tool are retracted.


9. Insert the EN-48313 timing chain retention tool between the camshaft actuators, rearward of the timing chain until the top line that is scribed in the body of the tool (1) is adjacent to the top surface of the cylinder head (2). This is the approximate installed position.

10.
Note

The engine front cover is removed for clarity in the following graphics, but NOT required to perform the procedure.


Ensure that the feet (2) on the legs of the tool are facing the front of the engine.


11. Partially expand the legs (1) of the EN-48313 timing chain retention tool by turning the T-shaped handle clockwise.

12. Continue expanding the EN-48313 timing chain retention tool until the feet (1) contact the timing chain. Do not tighten at this time.

13.
Note
• Ensure that the foot (1) of the EN-48313 timing chain retention tool is engaged into one of the link pockets to prevent chain slippage during tightening of the EN-48313 timing chain retention tool.

• Do not allow the body of the EN-48313 timing chain retention tool to rotate when tightening the T-handle.


Hand tighten the EN-48313 timing chain retention tool.


14. Use an open end wrench on the hex cast into the body of the EN-48313 timing chain retention tool and hand tighten the T-handle.

15. Use an open end wrench on the hex cast into the intake and exhaust camshafts and rotate the camshafts toward each other in order to create slack in the chain between the actuators.

16. The EN-48313 timing chain retention tool is now properly installed to hold the timing chain in position.


17. Use an open end wrench on the hex cast into the camshaft in order to prevent engine rotation when loosening the camshaft position actuator fastener.


18. Remove the right exhaust camshaft position actuator fastener.

19. Remove the right exhaust camshaft position actuator. When removing the actuator, place the chain on the engine block side of the actuators.

20. Rotate the actuator in order to align the opening in the actuator reluctor wheel with the cam sensor boss in the front cover, to allow actuator removal.

21. If removing both the exhaust and intake camshaft actuators, the timing chain can be draped over the EN-48313 timing chain retention tool once the actuators have been removed.


Installation Procedure


1.
Note

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


Align the exhaust camshaft actuator alignment mark (15) to the timing chain alignment mark (16) made during disassembly.


2. Ensure that the intake camshaft actuator alignment mark (18) and the timing chain alignment mark (17) are also aligned.

3. Position the exhaust camshaft actuator (2) to the camshaft and install the actuator fastener (1) hand tight.


4. Remove the EN-48313 timing chain retention tool.

5. Refer to Fastener Caution .

Tighten the right exhaust camshaft position actuator fastener (1) to 58 Nm (43 lb ft) .

6. Install the right intake and exhaust camshaft position actuator solenoids. Refer to Camshaft Position Actuator Solenoid Valve Solenoid Replacement - Bank 1 (Right Side) Intake and Camshaft Position Actuator Solenoid Valve Solenoid Replacement - Bank 1 (Right Side) Exhaust .

7. Install the right intake and exhaust camshaft position sensors. Refer to Camshaft Position Sensor Replacement - Bank 1 (Right Side) Intake and Camshaft Position Sensor Replacement - Bank 1 (Right Side) Exhaust .

8. Install the right camshaft cover. Refer to Camshaft Cover Replacement - Right Side .
