Secondary Camshaft Drive Chain Installation - Left Side LY7

Tools Required

Important: There should be no need to rotate the camshafts (1) more than 10 degrees. Using the hex cast into the camshaft (1) rotate the camshaft (1) in order to install the EN 46105  (2).

1. Install the EN 46105  (2) onto the rear of the left camshafts (1).

Important: All camshafts (1) must be locked in place before installation of any camshaft drive chains.

2. Make sure that the EN 46105  (2) is fully seated onto the camshafts (1).
3. Make sure that the crankshaft is in the stage one timing drive assembly position using the EN 46111 . Refer to Camshaft Timing Drive Chain Alignment Diagram Stage One.



4. Install the left secondary camshaft drive chain (1).



5. Place the left secondary camshaft drive chain around the inner sprocket of the left camshaft intermediate drive chain idler with the timing camshaft drive chain link (1) aligned to the alignment access hole (2) made in the left camshaft intermediate drive chain idler outer sprocket.
6. Wrap the secondary camshaft drive chain around both left actuator drive sprockets.
7. Make sure there are 10 links between the timing camshaft drive chain links for the camshaft position actuator solenoid sprockets.



8. Align the left exhaust camshaft position actuator solenoid sprocket alignment circle mark (4) with the timing camshaft drive chain link (3).
9. Align the left intake camshaft position actuator solenoid sprocket alignment circle mark (1) with the timing camshaft drive chain link (2).
10. There will be 22 links between the left camshaft intermediate drive chain idler timing camshaft drive chain link and the left intake camshaft position actuator solenoid sprocket timing camshaft drive chain link.

Secondary Camshaft Drive Chain Installation - Left Side LLT

Special Tools

Important: There should be no need to rotate the camshaft more than 10 degrees. Using the hex cast into the camshaft rotate the camshaft in order to install the EN-48383 .

1. Install the EN 48383-1 onto the rear of the left camshafts.

Important: All camshafts must be locked in place before installation of any camshaft drive chains.

2. Ensure that the EN 48383-1 is fully seated onto the camshafts.



3. Ensure the crankshaft is in the stage one timing position with the crankshaft sprocket timing mark (1) aligned to the stage one timing mark on the oil pump cover (2) using the EN-48589 . Refer to Camshaft Timing Drive Chain Alignment Diagram.



4. Install the left secondary camshaft drive chain.



5. Place the left secondary camshaft drive chain around the inner sprocket of the left camshaft intermediate drive chain idler with the timing camshaft drive chain link (1) aligned to the alignment access hole (2) made in the left camshaft intermediate drive chain idler outer sprocket.



6. Wrap the secondary camshaft drive chain around both left actuator drive sprockets.
7. Ensure there are 10 links (1) between the timing camshaft drive chain links for the camshaft position actuator sprockets.



8. Align the left exhaust camshaft position actuator sprocket alignment circle mark (2) with the timing camshaft drive chain link (1).



9. Align the left intake camshaft position actuator sprocket alignment circle mark (1) with the timing camshaft drive chain link (2).
