11.Disconnecthydrauliclines fromfittingson wheelmo-
tor. Allow lines to drain into a suitable container.
12.Put caps or plugs on disconnected lines and fittings
to prevent contamination.
13.Support wheel motor to prevent it from falling. Re-
movefour (4)lock nutsfrom capscrews that securemo-
tor and brake bracket to frame.
14.Remove four (4) cap screws, brake assembly and
brake bracket from wheel motor and frame.
15.Remove wheel motor from machine.
16.Ifhydraulic fittingsaretobe removedfromwheelmo-
tor, mark fitting orientation to allow correct assembly.
Remove fittings from motor and discard O --rings.
Installation
1. If fittings were removed from wheel motor, lubricate
and place newO--rings to fittings. Install fittingsinto mo-
tor ports using marks made during the removal process
toproperly orientatefittings(see HydraulicFittingInstal-
lationin theGeneralInformation sectionofthis chapter).
2. Position wheel motor to frame. Slide brake assem-
bly, brake bracket and four (4) cap screws onto wheel
motor and frame.
3. Install and tighten four (4) lock nuts onto cap screws
tosecure motorand brakebracket toframe. Torquelock
nuts from 80 to 100 ft--lb (109 to 135 N--m).
4. Thoroughly clean wheel motor shaft and wheel hub
taper.
5. Install key into the wheel motor shaft keyslot. Align
wheel hub with key and slide w heel hub onto motor
shaft. Secure hub with lock nut.
A. On machines with Parker wheel motors, torque
lock nut from 250 to 350 ft--lb (339 to 474 N--m).
B. On machines with Eaton wheel motors, torque
lock nut from 405 to 495 ft--lb (550 to 671 N--m).
6. Remove caps or plugs from disconnected hydraulic
lines and fittings.
7. Lubricate and position new O--rings to fittings on
wheel motor. Use labels placed during the removal pro-
cess to properlyinstall hydraulic lines towheel motor fit-
tings.
8. Position brakecable end tobrake actuator lever. Se-
cure brake cable clevis to brake actuator lever with cle-
vis pin and cotter pin or spring.
9. Install front wheel to machine (see Front Wheel
Installation in the Service and Repairs section of Chap-
ter 6 -- Chassis). Make sure that lug nuts are torqued
from 70 to 90 ft--lb (95 to 122 N--m).
10.Check and adjust oil level in hydraulic tank.
IMPORTANT: Ifawheelmotorfailureoccurred,refer
to Traction Circuit Component Failure in the Gener-
al Information section for informationregarding the
importance of removing contamination from the
traction circuit.
11.Operate machine functions slowly until air is out of
system (see Charge Hydraulic System in this section).
