Timing Component Alignment Marks: Locations

CAUTION: Failure to verify correct timing drive component alignment will result in severe engine damage.

NOTE: Install the sprockets with the timing marks facing outward.




If timing marks in the timing chains are not evident, use a permanent-type marker to mark the crankshaft and camshaft timing marks on the LH and RH timing chains.
1. Mark any link to use as the crankshaft timing mark.
2. Starting with the crankshaft timing mark, count 29 links and mark the link.
3. Continue counting to 42 and mark the link.




Align the marks on the LH timing chain with the marks on the camshaft and crankshaft sprockets.




Install the crankshaft damper bolt and rotate the crankshaft clockwise 120 degrees until the crankshaft keyway is in the 3 o'clock position.




Verify that the RH camshafts are correctly positioned.




Align the marks on the timing chain with the marks on the camshaft and crankshaft sprockets.




- Rotate the crankshaft counterclockwise 120 degrees to Top Dead Center (TDC).
- Verify the timing with the following steps.
1. There should be 12 chain links between the front camshaft timing marks.
2. There should be 27 chain links between the camshaft and crankshaft timing marks.
3. There should be 30 chain links between the camshaft and crankshaft timing marks.
