EN 48313 Timing Chain Retention ToolRemoval Procedure |
1. |
Remove the left bank camshaft cover. Refer to
Camshaft Cover Replacement - Left Side
.
|
2. |
Remove the camshaft sensors. Refer to
Camshaft Position Sensor Replacement - Bank 2 (Left Side) Exhaust
and
Camshaft Position Sensor Replacement - Bank 2 (Left Side) Intake
.
|
3. |
Remove the camshaft position actuator solenoid. Refer to
Camshaft Position Actuator Solenoid Valve Solenoid Replacement - Bank 2 (Left Side) Intake
.
|
5. |
Refer to
Torque Reaction Against Timing Drive Chain Caution
.
Loosen the camshaft position actuator bolt. |
6. |
Unscrew the
EN-48313
timing chain retention tool so that the legs of the tool are retracted.
|
7. |
Insert the
EN-48313
timing chain retention tool between the camshaft actuators, rearward of the timing chain until the bottom line that is scribed in the body of the tool (2) is adjacent to the top surface of the cylinder head (1). This is the approximate installed position.
|
8. |
Ensure that the feet (4) on the legs of the tool are facing the front of the engine. |
9. |
Partially expand the legs (1, 3) of the
EN-48313
timing chain retention tool by turning the T-shaped handle clockwise.
|
10. |
Insert the leg of the tool (1) behind the timing chain guide (2).
|
11. |
Continue expanding the
EN-48313
timing chain retention tool until the legs (1, 3) contact the timing chain. Do not tighten at this time.
|
12. |
Hand tighten the EN-48313 timing chain retention tool. |
13. |
Refer to
Torque Reaction Against Timing Drive Chain Caution
.
Use an open end wrench on the hex cast into the left intake and exhaust camshafts and rotate the camshafts toward each other in order to create slack in the chain between the actuators. |
14. |
The
EN-48313
timing chain retention tool is now properly installed to hold the timing chain in position.
|
15. |
Mark the timing chain and the respective locations on the camshaft position actuators (1-4). |
16. |
Remove the camshaft position actuator bolt.
|
17. |
Remove the camshafts. Refer to
Camshaft Removal - Left Side
.
|
Installation Procedure |
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
.
|
3. |
Remove the
EN-48313
timing chain retention tool.
|
4. |
Refer to
Torque Reaction Against Timing Drive Chain Caution
.
Install and tighten the camshaft position actuators. Refer to Camshaft Position Actuator Installation - Left Side Intake and Camshaft Position Actuator Installation - Left Side Exhaust . |
5. |
Install the intake camshaft position actuator solenoid. Refer to
Camshaft Position Actuator Solenoid Valve Solenoid Replacement - Bank 2 (Left Side) Intake
.
|
6. |
Install the camshaft sensors. Refer to
Camshaft Position Sensor Replacement - Bank 2 (Left Side) Exhaust
and
Camshaft Position Sensor Replacement - Bank 2 (Left Side) Intake
.
|
7. |
Install the camshaft cover. Refer to
Camshaft Cover Replacement - Left Side
