Removal (Fig. 69)
1. Park machine on a level surface, lower cutting deck,
stop engine, apply parking brake and remove key from
the ignition switch.
2. Read the General Precautions for Removing and
Installing Hydraulic System Components at the beginning
of the Service and Repairs section of this chapter.
3. Unlatch and raise hood.
4. Remove air cleaner hose and upper radiator shroud
to allow easier access to hydraulic fan motor (Fig. 70).
CAUTION
The radiator and oil cooler may be hot. To avoid
possible burns, allow the engine and cooling
systems to cool before removing fan motor.
IMPORTANT: Make sure to not damage the radiator,
fan or other machine components while loosening
and removing the fan motor.
5. Remove hex nut (item 9) and washer (item 8) that secure
fan hub and fan assembly to fan motor.
IMPORTANT: Make sure to not damage the radiator,
oil cooler or other machine components while
installing the fan motor.
2. Carefully position fan motor to fan motor bracket.
Loosely attach motor to bracket with cap screws (item
20), flat washers (item 21) and lock nuts (item 14).
3. Remove caps or plugs placed during removal to prevent
contamination. Connect hydraulic hoses to cooling
fan motor (see Hydraulic Hose and Tube Installation in
the General Information section of this chapter).
4. Tighten fasteners to secure fan motor to bracket.
5. Thoroughly clean tapered surfaces of fan motor
shaft and fan hub. Position fan hub (with fan attached)
onto motor shaft and secure with washer (item 8) and
hex nut (item 9). Torque nut from 27 to 33 ft -lb (37 to
44 N -m).
6. Install upper radiator shroud and air cleaner hose
(Fig. 70). Make sure that clearance between shroud and
cooling fan is at least 0.180” (4.6 mm) at all points.
7. Lower and secure hood.

6. Use suitable puller to remove fan hub (with fan attached)
from fan motor shaft taking care to not damage
fan. Position fan assembly away from fan motor.
7. To prevent contamination of hydraulic system during
fan motor removal, thoroughly clean exterior of motor
and fittings.

8. Disconnect hydraulic hoses from cooling fan motor.
Put caps or plugs on fittings and hoses to prevent contamination.
Tag hydraulic lines for proper assembly.
9. Support fan motor to prevent it from falling. Remove
two (2) cap screws (item 20), flat washers (item 21) and
lock nuts (item 14) that secure fan motor to fan motor
bracket.
10.Carefully lower fan motor and remove from machine.
11.If hydraulic fittings are to be removed from fan motor,
mark fitting orientation to allow correct assembly. Remove
fittings from motor and discard O--rings.

Installation (Fig. 69)
1. If fittings were removed from fan motor, lubricate and
place new O--rings onto fittings. Install fittings into port
openings using marks made during the removal process
to properly orientate fittings. Tighten fittings (see Hydraulic
Fitting Installation in the General Information
section of this chapter).
