Remove plug (2) from the cylinder block. Remove O-ring seal (1) from the plug.
Use Tooling (A) to rotate the crankshaft so that number one piston is at top dead center on the compression stroke. Refer to System Operation, Testing and Adjusting, "Position the Valve Mechanism Before Maintenance Procedures" for the correct procedure. Install Tooling (B) through Hole (W) in order to lock the crankshaft.
Remove Tooling (B).
Use Tooling (A) to rotate the crankshaft in a clockwise direction and position the crankshaft at 60 degrees after top dead center.

Loosen Torx screws (7). Begin at the ends of rocker shaft assembly (2) and work toward the center. Note: To avoid distortion of the rocker shaft assembly, 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 (7) from rocker shaft assembly (8). Note: Note Position (X) of different length Torx screws (7).
Remove rocker shaft assembly (8) from the cylinder head.
Place an identification mark on pushrods (9) 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 (6) 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.Installation Procedure
Note: Either Tooling (A) can be used. Use the Tooling that is most suitable.
Illustration 5 g02004077
The correct location of valve bridges on valve stems is shown.
Clean valve bridges (6). Inspect the valve bridges for wear and damage. Replace any valve bridges that are worn or damaged.
Lubricate valve bridges (6) with clean engine oil.
Failure to ensure that ALL valve bridges are correctly seated onto the valve stems will cause interference between the pistons and the valves, resulting in damage to the engine.
Install valve bridges (6) to the valve stems. Note: Install used valve bridges in the original location and in the original orientation. Ensure that the valve bridges are correctly seated on the valves. New valve bridges may be installed in either orientation.

Clean the pushrods. Inspect the pushrods for wear and damage. Replace any pushrods that are worn or damaged.
Apply clean engine lubricating oil to both ends of pushrods (9). Install the pushrods to the engine with the cup upward. Note: Ensure
