Timing Component Alignment Marks: Locations

NOTICE: The crankshaft must remain in the freewheeling position (crankshaft dowel pin at 9 o'clock) until after the camshafts are installed and the valve clearance is checked/adjusted. Do not turn the crankshaft until instructed to do so. Failure to follow this process will result in severe engine damage.

Position the crankshaft dowel pin in the 9 o'clock position.





NOTE: Use a camshaft sprocket bolt to turn the camshafts.

Rotate the RH camshafts to the Top Dead Center (TDC) position and install the Camshaft Holding Tool on the flats of the camshafts.





Assemble the RH Variable Camshaft Timing (VCT) assembly, the RH exhaust camshaft sprocket and the RH secondary timing chain.
- Align the colored links with the timing marks.





Position the RH secondary timing assembly onto the camshafts.





NOTE: Use a camshaft sprocket bolt to turn the camshafts.

Rotate the LH camshafts to the TDC position and install the Camshaft Holding Tool on the flats of the camshafts.





Assemble the LH VCT assembly, the LH exhaust camshaft sprocket and the LH secondary timing chain.
- Align the colored links with the timing marks.





Position the LH secondary timing assembly onto the camshafts.





Rotate the crankshaft clockwise 60 degrees to the TDC position (crankshaft dowel pin at 11 o'clock).





Install the crankshaft timing chain sprocket.





Install the primary timing chain with the colored links aligned with the timing marks on the VCT assemblies and the crankshaft sprocket.





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