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

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

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

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