Timing Component Alignment Marks: Locations

Primary Camshaft Drive Chain Installation





Important: Ensure that the crankshaft is in the stage one timing drive assembly position.

1. Install the primary camshaft drive chain.




2. Wrap the primary camshaft drive chain around the large sprockets of each camshaft intermediate drive chain idler and the crankshaft sprocket.




3. The left camshaft intermediate drive chain idler timing mark (1) will align with a timing camshaft drive chain link (2).




4. The right camshaft intermediate drive chain idler timing mark (2) will align with a timing camshaft drive chain link (1).




5. The crankshaft sprocket timing mark (2) will align with a timing camshaft drive chain link (1).




6. Ensure all the timing marks (2, 3, 6) are properly aligned with the timing camshaft drive chain links (1, 4, 5).



Secondary Camshaft Drive Chain Installation - Left Side

Tools Required

* EN 46105 Camshaft Holding Tool
* EN 46111 Crankshaft Rotation Socket





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 46105.

1. Install the EN 46105-1 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 46105-1 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 46111. Refer to Camshaft Timing Drive Chain Alignment Diagram (Second Design) - Stage One.




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 7 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).




10. There will be 18 links (1) between the left camshaft intermediate drive chain idler timing secondary camshaft drive chain link and each left camshaft position actuator sprocket timing secondary camshaft drive chain link.



Secondary Camshaft Drive Chain Installation - Right Side




1. Ensure that the crankshaft is in the stage 2 timing drive assembly position (1).




2. Install the right secondary camshaft drive chain.




3. Place the secondary camshaft drive chain around the right camshaft intermediate drive chain idler outer sprocket, aligning the timing camshaft drive chain link (1) with the alignment access hole (2) made in the right camshaft intermediate drive chain idler inner sprocket.




4. Wrap the secondary camshaft drive chain around both right actuator drive sprockets.
5. Ensure there are 7 links (1) between the timing camshaft drive chain links for the camshaft position actuator sprockets.




6. Align the right exhaust camshaft position actuator sprocket alignment triangle mark (1) with the timing camshaft drive chain link (2).




7. Align the right intake camshaft position actuator sprocket alignment triangle mark (2) with the timing camshaft drive chain link (1).




8. There will be 18 links (1) between the right camshaft intermediate drive chain idler timing camshaft drive chain link and each right camshaft position actuator sprocket timing camshaft drive chain link.
