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 ToolFor 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. |
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). |
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. |
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. |
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. |
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
.
