Camshaft Position Intake Actuator Replacement

Special Tools
* EN-45059 - Angle Meter
* EN-48749 - Timing Chain Retention Tool Kit
* EN-48953 - Camshaft Actuator Locking Tool

For equivalent regional tools, refer to Special Tools (Special Tools).

Removal Procedure

1. Remove the camshaft cover. Refer to Camshaft Cover Replacement (LAF) (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 - retention
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 intake 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 intake camshaft actuator should not rotate during the removal or installation.
* Ensure the tips of the 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 intake side of the timing chain.




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




13. Remove and discard the intake camshaft actuator bolt (1).
14. Rotate the exhaust camshaft clockwise slightly to take the tension off of the timing chain on the intake actuator.
15. Remove the intake 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.

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




4. Remove the timing chain retention tool (1) from the intake side of the timing chain.





Note: Ensure that the alignment mark previously on the intake 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).

5. Remove the timing chain 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.

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




7. Install the EN-48953 - retention tool (1).
8. Install the camshaft actuator retainer bolts and tighten to 10 Nm (89 lb in).
9. 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 - retention tool installed to perform this procedure.

10. To release the tensioner apply a counterclockwise rotational torque to the crankshaft balancer bolt of 45 Nm (33 lb ft).
11. Remove the EN-48953 - retention tool (1).




12. Install the upper timing chain guide and bolts and tighten to 10 Nm (89 lb in).
13. Install the spark plugs. Refer to Spark Plug Replacement (Service and Repair).
14. Install the camshaft cover. Refer to Camshaft Cover Replacement (LAF) (Service and Repair).
