Removal (Fig. 4)
1. Park machine on a level surface, lower cutting deck
(or implement), stop engine and remove key from the
ignition switch.
NOTE: The installation torque of the lock nut used to
secure wheel hub to wheel motor is from 300 to 400 ft–
lb (407 to 542 N–m). If hub removal is necessary, use
impact wrench to loosen lock nut.
2. If wheel hub is to be removed, loosen (but do not re-
move) lock nut that secures wheel hub to wheel motor.
3. Remove rear wheel (see Rear Wheel Removal in
this section). Make sure that machine is properly sup-
ported with jack stands.
4. Remove retaining ring and flat washer that retains
brake rod assembly to parking brake lever. Separate
brake rod from brake lever.
5. Remove four (4) cap screws and flange nuts that se-
cure brake support to frame.
6. Slide brake support (with parking brake assembly at-
tached) from wheel hub disc and frame.
7. Remove two (2) lock nuts that secure parking brake
assembly to brake support. Remove brake from sup-
port. Locate and retrieve two (2) hardened washers from
between parking brake and brake support (Figs. 5 and
6).
