Manifold Removal (Fig. 136)
1. Park machine on a level surface, lower cutting deck,
stop engine, engage parking brake and remove key
from the ignition switch.
WARNING
Before disconnecting or performing any work on
the hydraulic system, all pressure in the system
must be relieved. See Relieving Hydraulic System
Pressure in the General Information section.
2. Read the General Precautions for Removing and
Installing Hydraulic System Components at the begin-
ning of the Service and Repairs section of this chapter.
3. Raise and support operator seat. Locate steering
control manifold.
4. Thoroughly clean hydraulic hose ends prior to dis-
connecting hoses from the steering control manifold.
Label all hydraulic connections for assembly purposes.
5. Disconnect hydraulic hoses from control manifold.
6. Install clean caps or plugs on disconnected hoses
and fittings to prevent contamination.
7. Disconnect wire harness connector from solenoid
coil on manifold.
8. Support manifold to prevent it from falling.
9. Remove two (2) cap screws (item 12) and flange nuts
(item 7) that secure manifold to mount plate. Remove
manifold from machine.
10.If hydraulic fittings are to be removed from steering
control manifold, mark fitting orientation to allow correct
assembly. Remove hydraulic fittings from manifold as
needed. Discard fitting O--rings.

Manifold Installation (Fig. 136)
1. If hydraulic fittings were removed from steering con-
trol manifold, lubricate new O--rings with clean hydraulic
oil, position O--rings to fittings and install fittings into
manifold ports (see Hydraulic Fitting Installation in the
General Information section of this chapter).
2. Position steering control manifold to machine.
3. Secure control manifold to machine with two (2) cap
screws (item 12) and flange nuts (item 7).
4. Remove caps and plugs from hydraulic hoses and
fittings.
5. Lubricate and install new O--rings on control man-
ifold fittings. Using labels placed during manifold remov-
al, correctly connect hydraulic hoses to control manifold
(see Hydraulic Hose and Tube Installation in the Gener-
al Information section of this chapter).
6. Connect wire harness connector to solenoid coil on
manifold.
7. Check oil level in hydraulic reservoir and add correct
oil if necessary.
8. Lower and secure operator seat.
9. Follow Hydraulic System Start--up procedures (see
Hydraulic System Start--up in this section).
