Removal (Fig. 85)
1. Park machine on a level surface, lower cutting deck,
stop engine, engage parking brake and remove key
from the ignition switch.
2. Raise and support operator seat to allow access to
fan drive manifold (Fig. 86).
3. Read the General Precautions for Removing and
Installing Hydraulic System Components at the begin-
ning of the Service and Repairs section of this chapter.
4. To prevent contamination of hydraulic system during
manifold removal, thoroughly clean exterior of manifold
and fittings.
5. Label wire harness electrical connectors that attach
to manifold solenoid valve coils. Disconnect wire har-
ness connectors from the solenoid coils.
6. Disconnect hydraulic lines from manifold and put
caps or plugs on open hydraulic lines and fittings. Label
disconnected hydraulic lines for proper reassembly.
7. Remove hydraulic manifold from the frame using
Figure 85 as guide.
8. If hydraulic fittings are to be removed from manifold,
mark fitting orientation to allow correct assembly. Re-
move fittings from manifold and discard O--rings.

Installation (Fig. 85)
1. If fittings were removed from manifold, lubricate and
place new O--rings onto fittings. Install fittings into man-
ifold openings using marks made during the removal
process to properly orientate fittings. Tighten fittings
(see Hydraulic Fitting Installation in the General Infor-
mation section of this chapter).
2. Install fan drive manifold to the frame using Figure 85
as guide.
3. Remove caps and plugs from fittings and hoses. Us-
ing labels placed during manifold removal, properly con-
nect hydraulic lines to manifold (see Hydraulic Hose and
Tube Installation in the General Information section of
this chapter).
4. Connect wire harness connectors to the solenoid
valve coils on the fan drive manifold.
5. Make sure hydraulic tank is full. Add correct oil if nec-
essary before returning machine to service.
6. Lower and secure operator seat.
