Removal (Fig. 85)
1. Park machine on a level surface,lowercuttingdeck,
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. Topreventcontaminationofhydraulicsystemduring
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
capsorplugsonopenhydraulic linesand 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, lubricateand
place new O--rings onto fittings. Install fittings intoman-
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).

4. Connect wire harness connectors to the solenoid
valve coils on the fan drive manifold.
