6. Make sure that lock nut on wheel motor shaft is loos-
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 service is required, see Brake Service in the Ser-
vice and Repairs section of Chapter 7 -- Chassis.
9. Thoroughly clean hydraulic line ends and fittings on
wheel motor to prevent hydraulic system contamination.
10.Label hydraulic connections at wheel motor for as-
sembly purposes.
11. Disconnect hydraulic lines from fittings on wheel mo-
tor. Allow lines to drain into a suitable container.
12.Mark wheel motor fitting orientation to allow correct
assembly. Remove hydraulic fittings and O--rings from
motor. Discard removed O--rings.
13.Put caps or plugs on disconnected lines and motor
port openings to prevent contamination.
14.Support wheel 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. Position hydraulic wheel motor to the frame with mo-
tor ports facing up. Place brake lever tab (item 10) to
frame with slot toward rear of machine. Secure motor
and brake lever tab to the frame with four (4) cap screws.
2. Remove plugs from wheel motor ports. Lubricate
and place new O--rings onto fittings. Install fittings into
motor openings making sure that fitting orientation is as
noted during removal. Tighten fittings (see Hydraulic Fit-
ting Installation in the General Information section of this
chapter).
3. Remove caps from disconnected hydraulic lines.
4. Lubricate and position new O--rings to fittings on
wheel motor. Use labels placed during the removal pro-
cess to properly install hydraulic lines to wheel motor fit-

(4) lug nuts.
Failure to maintain proper wheel lug nut and
wheel hub lock nut torque could result in failure
or loss of wheel and may result in personal injury.
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. Check oil level in hydraulic reservoir and add correct
oil if necessary.
