Timing Component Alignment Marks





CAUTION:Failure to verify correct timing drive component alignment will result in severe engine damage. For complete service procedure, please refer to Timing Drive Components Removal/Installation. Service and Repair

Verify the timing with the following steps.

Rotate the crankshaft clockwise to position the crankshaft keyway in the 11 o'clock position and position the camshafts in the correct position. This will position the number one cylinder at top dead center (TDC).





1. There should be 12 chain links between the 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.





NOTE:This pulse wheel is used in several different engines. Install the pulse wheel with the keyway in the slot stamped "30RFF" only (orange in color).
