Loosen the valve and injector adjusting screw lock nuts on each rocker lever.
Turn the adjusting screws counterclockwise until the rocker levers are loose.
Remove the rocker lever shaft capscrews and the rocker lever shaft assemblies.
NOTE: To prevent increased wear, mark each rocker lever as it is removed so it can be installed back in its original location.
NOTE: Hold the shaft at both ends so that the rocker levers do not slide off.
