Removal (Fig. 2)
1. Park the machine on a level surface, engage the
parking brake, lower the cutting units and stop the en-
gine. Remove key from the ignition switch.
2. Loosen, but do not remove, lug nuts (item 1) and lock
nut (item 3). Loosen lock nut at least two (2) turns.
3. Chock front and rear of wheels not being lifted to pre-
vent the machine from moving. Lift front wheel off the
ground using a jack and place appropriate jackstands
beneath the frame to support the raised machine (see
Jacking Instructions in Chapter 1 -- Safety).
4. Remove lug nuts and wheel a ssembly from drive
studs.
IMPORTANT: DO NOT hit wheel hub (item 6) with a
hammer during removal or installation. Hammering
may cause damage to the hydraulic wheel motor.
NOTE: The brake drum assembly consists of the wheel
hub (item 6), brake drum (item 5) and drive studs (item
7).
5. Make sure that lock nut (item 3) on wheel motor shaft
is loosened at least two (2) tur ns. Use hub puller (see
Special Tools in this chapter) to loosen brake drum as-
sembly from wheel motor.
