NOTICE |
---|
Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened component life. |
- 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.
- Remove torx screws (1) from rocker shaft assembly (2).
- Remove rocker shaft assembly (2) from the cylinder head.
- 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.
- 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.
