NOTE: The planetary wheel drive assembly can be ser-
viced with the planetary installed to machine (see Plane-
tary Wheel Drive Service in this section). Use the
following procedure to remove and install planetary
wheel drive assembly from machine.
Removal (Fig. 7)
1. Park machine on a level surface, lower cutting
decks, stop engine and remove key from the ignition
switch.
2. Drain oil from planetary wheel drive/brake assembly.
CAUTION
When removing front wheel, use correct jacks
and supports. Make sure machine is parked on a
solid, level surface such as a concrete floor.
Prior to raising machine, remove any attach-
ments that may interfere with the safe and prop-
er raising of the machine. Always chock or block
wheels. Use jack stands to support the raised
machine. If the machine is not properly sup-
ported by jack stands, the machine may move or
fall, which may result in personal injury.
3. Chock rear wheels and jack up front of machine (see
Jacking Instructions in Chapter 1 -- Safety). Support ma-
chine with jack stands.
4. Remove front wheel assembly.
5. Remove hydraulic wheel motor (see Front Wheel
Motors in the Service and Repairs section of Chapter 4
-- Hydraulic System).
6. Remove brake assembly (see Brake Assembly Re-
moval in this section).
7. Support planetary assembly to prevent it from falling.
Loosen and remove flange head screws that secure
planetary assembly to frame. Remove planetary as-
sembly from machine.
Installation (Fig. 7)
1. Position planetary assembly to machine. Install
flange head screws that secure planetary assembly.
Torque screws in a crossing pattern from 75 to 85 ft- -lb
