    WARNING
    The camshaft sprocket can jump time causing engine damage if the Crankshaft Holding Tool is not secured.


    NOTE
    Be sure the chain link and crankshaft sprocket timing marks are aligned.


    NOTE
    The lower half of the timing chain must be positioned above the dowel.
  11. Install the RH (outer) timing chain on the crankshaft sprocket.
  12. Position the timing chain on the camshaft sprocket. Make sure the 2 copper-colored (marked) links align with the camshaft sprocket timing mark.
    NOTE
    The LH timing chain tensioner arm has a bump near the dowel hole, for identification.
