Timing Component Alignment Marks: Locations

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




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 link 42 and mark the link.




Crankcase keyway in the 11 o'clock position.




Verify that the LH camshafts are correctly positioned.




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




Crankshaft keyway is in the 3 o'clock position.




Verify that the RH camshafts are correctly positioned.




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




CAUTION: 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.
