Toro Groundsmaster 4700-D Service Manual page 135

For solenoid and control valve service procedures, see
4WD/2WD Control Manifold Service in this section. Re-
fer to Figures 83 and 84 for cartridge valve and plug
installation torque.
IMPORTANT: A pilot piston (item 6) is placed be-
neath each of the relief valves in deck control man-
ifold ports RV8, RV9, RV10 and RV11. If a relief valve
is removed from the manifold, make sure to remove
pilot piston and label its position for assembly pur-
poses. When installing the pilot piston in the man-
ifold, make sure that the pilot piston slides fully into
the port before installing relief valve.
