NOTE: Machines produced with serial number below
311000600 were produced with Parker brand front
wheel motors. Figure 65 shows the front axle assembly
withParkerwheelmotors. Machines with serialnumber
above 311000600 were produced with Eaton brand
front wheel motors. Figure 66 shows the front axle as-
sembly with Eaton wheel motors. If Parker brand wheel
motorswerereplacedforsomereason,thereplacement
wheel motors may have been Eaton brand. Wheel mo-
tors have an identification tag on them which identifies
the brand. Removal and installation of front wheel mo-
tors is very similar regardless of motor brand.
Removal

brake,lower cutting unitsandstop engine.Removekey
from the ignition switch.
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.
CAUTION
Beforeopening hydraulicsystem,operate allhy-
draulic controls to relieve system pressure and
avoid injury from pressurized hydraulic oil. See
RelievingHydraulicSystemPressureintheGen-
eral Information section of this chapter.
3. Removefrontwheelfrommachine(seeFrontWheel
Removal in the Service and Repairs section of Chapter
6 -- Chassis).
NOTE: Clevispinthatsecuresbrakecabletobrakeac-
tuator lever is secured with cotter pin (shown in Fig. 65)
or extension spring (shown in Figs. 66 and 67).
4. Remove cotter pin or spring from clevis pin that se-
cures brake cable to brake actuator lever. Remove cle-
vis pin and position brake cable away from brake
actuator lever.
5. Remove brake drum.
6. Loosen,butdonotfullyremove,locknutthatsecures
wheel hub to wheel motor. Loosen lock nut at least two
(2) turns.
IMPORTANT: DO NOT hit wheel hub, wheel hub
puller or wheel motor with a hammer during wheel
hub removal or installation. Hammering may cause
damage to the wheel motor.
