  1. Install the camshaft drive sprocket. Ensure the camshaft pin is installed in the correct numbered slot on the drive sprocket.

Important: Use a new camshaft drive sprocket bolt, the old bolt is not reusable.

  1. Install the camshaft drive sprocket bolt.
    • Use the relevant J 42069-1 and/or the J 42069-2 to hold the camshaft drive sprocket and the camshaft in place while tightening the camshaft drive sprocket bolt.
