Removal (Fig. 67)
1. Before removing any parts from the hydraulic sys-
tem, park machine on a level surface, engage parking
brake, lower cutting units, and stop the engine.
CAUTION
Operate all hydraulic controls to relieve sys-
tem pressure and avoid injury from pressur-
ized hydraulic oil. Controls must be oper-
ated with the ignition switch in RUN and the
engine OFF. Return ignition switch to OFF
when pressure has been relieved. Remove
key from the ignition switch.
2. Disconnect solenoid valve electrical connectors. If
a backlap kit is installed, disconnect electrical connector
to the ball switch.
3. Clean manifold and hydraulic connections. Label all
hydraulic connections and electrical connections for
reassembly.
4. Disconnect hose assemblies and their respective
O–rings from hydraulic fittings. Allow hoses to drain into
a suitable container.
5. Put caps or plugs in disconnected hoses and man-
ifold ports to prevent contamination.
6. Remove both cap screws (12) from the hydraulic
manifold. Remove manifold assembly from the ma-
chine.
7. Disconnect hydraulic fittings and O–rings from the
manifold.
Installation (Fig. 67)
1. Remove caps or plugs from manifold assembly.
Note: Fitting orientation is determined by viewing the
manifold assembly from the side with its solenoids fac-
ing up.
