Front Wheel Removal (Fig. 2)
1. Park machine on a level surface, lower rear attach-
ment, stop engine, apply parking brake and remove key
from ignition switch.
CAUTION
When changing attachments, tires or perform-
ing other service, use correct jacks, hoists and
supports. Make sure machine is parked on a sol-
id, level surface such as a concrete floor. Prior to
raising machine, remove any attachments that
may interfere with the safe and proper raising of
the machine. Always chock or block wheels. Use
jack stands to support the raised machine. If the
machine is not properly supported by jack
stands, the machine may move or fall, which
may result in personal injury.
2. Chock rear wheels to prevent machine from shifting.
Using a jack or hoist, raise machine so front wheel is off
ground. Support front of machine with jack stands (see
Jacking Instructions in Chapter 1 - Safety).
3. Remove lock nut (item 1) from castor bolt (item 2).
Pull bolt from castor fork, two (2) spacers (item 4) and
front wheel assembly.
4. Remove front wheel assembly from castor fork.
NOTE: If castor fork removal is necessary, see Front
Castor Fork in this section.
Wheel Rim Service
NOTE: The front wheel rim assembly consists of the
wheel rim, oil seals, bearing cones, bearing cups, valve
stem and grease fitting (Fig. 3).
1. Remove oil seals, bearing cones and bearing cups
from the wheel rim hub. Clean hub and inspect for wear
or damage.
2. Press new bearing cups into the wheel rim hub with
the thick edges towards the inside. Cups should be re-
cessed into wheel rim hub from 0.500” to 0.540” (12.7

pose lithium grease into hub until grease is visible at
both seals. Wipe off excess grease.

removed from wheel assembly. Once endplay has been
removed, torque lock nut an additional 75 to 150 in- lb
