NOTE: Machines produced with serial number below
311000600 were produced with Parker brand front
wheel motors. Figure 65 shows the front axle assembly
with Parker wheel motors. Machines with serial number
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

draulic controls to relieve system pressure and
avoid injury from pressurized hydraulic oil. See
Relieving HydraulicSystemPressure inthe Gen-
eral Information section of this chapter.
3. Removefront wheelfrom machine( see Front Wheel
Removal in the Service and Repairs section of Chapter
6 -- Chassis).

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
