Assemble the RH (Right Hand) VCT (Variable Camshaft Timing) assembly, the RH (Right Hand) exhaust camshaft sprocket and the RH (Right Hand) secondary timing chain.

- Align the colored links with the timing marks.






NOTE: It may be necessary to rotate the camshafts slightly, to install the RH (Right Hand) secondary timing assembly.
Position the 2 RH (Right Hand) VCT (Variable Camshaft Timing) assemblies and secondary timing chain onto the camshafts by aligning the holes in the VCT (Variable Camshaft Timing) assemblies with the dowel pins in the camshafts.


Assemble the 2 LH (Left Hand) VCT (Variable Camshaft Timing) assemblies and the LH (Left Hand) secondary timing chain.

- Align the colored links with the timing marks.






NOTE: It may be necessary to rotate the camshafts slightly, to install the LH (Left Hand) secondary timing assembly.
Position the 2 LH (Left Hand) VCT (Variable Camshaft Timing) assemblies and secondary timing chain onto the camshafts by aligning the holes in the VCT (Variable Camshaft Timing) assemblies with the dowel pins in the camshafts.


Install the crankshaft timing chain sprocket with timing dot mark out.





NOTE: It may be necessary to rotate the camshafts slightly, to align the timing marks.
Install the primary timing chain with the colored links aligned with the timing marks on the VCT (Variable Camshaft Timing) assemblies and the crankshaft sprocket.






As a post-check, verify correct alignment of all timing marks.

- There is 48 links in between the RH (Right Hand) intake VCT (Variable Camshaft Timing) assembly colored link (1) and the LH (Left Hand) intake VCT (Variable Camshaft Timing) assembly colored link (2).

- There is 35 links in between LH (Left Hand) intake VCT (Variable Camshaft Timing) assembly colored link (2) and the 2 crankshaft sprocket links (3).
