  1. Use Tooling (A) to progressively loosen torx screws (1). Begin at the ends of the rocker shaft assembly and work toward the center.

    Note: To avoid distortion of rocker shaft assembly (2), each torx screw should be loosened by half a turn at one time. Repeat the procedure until all torx screws are loosened.

  2. Remove torx screws (1) from rocker shaft assembly (2).

  3. Remove rocker shaft assembly (2) from the cylinder head.

  4. Place an identification mark on pushrods (3) in order to show the location. Remove the pushrods from the cylinder head.

    Note: Identification will ensure that the pushrods can be reinstalled in the original positions. Do not interchange the positions of used pushrods.

  5. Make a temporary mark on valve bridges (4) in order to show the location and the orientation. Remove the valve bridges from the cylinder head.

    Note: Identification will ensure that the valve bridges can be reinstalled in the original location and the original orientation. Do not interchange the location or the orientation of used valve bridges.
