To install:


NOTE
Set the crankshaft to 60 degrees Before Top Dead Center (BTDC) to prevent contact between the pistons and valves.

  1. Install or connect the following:


  2.  
  3. Position the exhaust camshaft with the offset slot in the 2 o-clock position and the intake camshaft with the offset slot in the 11 o-clock position.
    CAUTION
    Make certain that all timing marks and colored links are aligned properly before proceeding to the next step. If the timing chain is not aligned properly, severe engine damage may occur.
