RH camshafts 

  1. NOTE: The crankshaft must remain in the freewheeling position (crankshaft dowel pin at 9 o'clock) until after the camshafts are installed and the valve clearance is checked/adjusted. Do not turn the crankshaft until instructed to do so. Failure to follow this process will result in severe engine damage.

    Using the crankshaft bolt, rotate counterclockwise to the 9 o'clock position.
