Timing Component Alignment Marks: Locations




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

Install the crankshaft sprocket with the timing mark facing out. The timing mark on the LH and RH timing chains will be aligned to this mark during assembly.





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 counterclockwise 29 links and mark the link.
3. Continue counting counterclockwise to link 42 and mark the link.





Verify that the LH camshafts are correctly positioned.





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





Install the crankshaft pulley bolt and washer 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.





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





Rotate the crankshaft counterclockwise 120 degrees to TDC.

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

Verify the timing with the following steps.
1. There should be 12 chain links between the camshaft timing marks.
2. There should be 27 chain links between the camshaft and the crankshaft timing marks.
3. There should be 30 chain links between the camshaft and the crankshaft timing marks.
