6. Makesure thatlock nuton wheelmotorshaftisloos-
ened at least two (2) turns. Use hub puller (see Special
Tools in this chapter) to loosen brake drum assembly
from wheel motor.
7. Remove lock nut and brake drum assembly. Locate
and retrieve woodruff key (item 12).
8. Remove four (4) cap screws that secure brake as-
sembly to wheel motor. Remove brake assembly. If
brake serviceis required, seeBrake Service in theSer-
vice and Repairs section of Chapter 7 -- Chassis.
9. Thoroughly clean hydraulic line ends and fittings on
wheelmotortopreventhydraulicsystemcontamination.
10.Label hydraulic connections at wheel motor for as-
sembly purposes.
11.Disconnecthydrauliclinesfromfittingsonwheelmo-
tor. Allow lines to drain into a suitable container.
12.Mark wheel motor fitting orientation to allow correct
assembly. Remove hydraulic fittings and O--r ings from
motor. Discard removed O-- rings.
13.Put caps or plugs on disconnected lines and motor
port openings to prevent contamination.
14.Support w heel motor to prevent it from falling. Re-
move four (4) cap screws that secure wheel motor and
brake lever tab (item 10) to frame. Remove brake lever
tab and wheel motor from machine.
Front Wheel Motor Installation (Fig. 51)
1. Positionhydraulicwheelmotortotheframewithmo-
tor ports facing up. Place brake lever tab (item 10) to
frame with slot toward rear of machine. Secure motor
andbrakelevertabtotheframewithfour(4)capscrews.
2. Remove plugs from wheel motor ports. Lubricate
and place new O--rings onto fittings. Install fittings into
motor openingsmaking surethatfittingorientation isas
notedduringremoval.Tightenfittings(seeHydraulicFit-
tingInstallationintheGeneralInformationsectionofthis
chapter).
3. Remove caps from disconnected hydraulic lines.
4. Lubricate and position new O--rings to fittings on
wheelmotor. Uselabelsplaced duringthe removalpro-
cesstoproperlyinstallhydrauliclinestowheelmotorfit-
tings (see Hydraulic Hose and Tube Installation in the
General Information section of this chapter).
5. Position brake assembly to wheel motor and align
brake actuator lever with slotin brake lever tab. Secure
brakeassemblytowheelmotorw ithfour(4)capscrews.
6. Thoroughly clean wheel motor shaft and wheel hub
taper.
7. Install woodruff key into the wheel motor shaft key-
slot. Align brake drum assembly with woodruff key and
slidedrumassemblyontomotorshaft.Secure drumas-
sembly with lock nut.
8. Secure brake cable clevis to brake actuator lever
with clevis pin and e--ring (Fig. 52).
9. Install front wheel to machine and secure with four
(4) lug nuts.
Failure to maintain proper wheel lug nut and
wheel hub lock nut torque could result in failure
orlossofwheeland may resultin personalinjury.
WARNING
10.Lower machine to ground. Torque lock nut from 250
to 400 ft--lb (339 to 540 N--m) and wheel lug nuts from
65 to 85 ft--lb (89 to 115 N--m).
11.Checkoillevelinhydraulicreservoirandaddcorrect
oil if necessary.
12.Follow Hydraulic System Start--up procedures (see
Hydraulic System Start--up in this section).
