Disassembly (Fig. 18)
1. Chock rear wheels to prevent machine from shifting.
2. Remove front wheel (see Wheel Removal in this sec-
tion). Make sure to support machine with jack stands.
3. Remove the dust cap from the wheel hub.
4. Remove the cotter pin, nut retainer, jam nut and
spindle washer. Slide the wheel hub from the spindle
shaft.
5. Pull the seal (item 4) out of the wheel hub. Discard
seal.
6. Remove the bearing cones from both sides of the
wheel hub. Clean the bearings in solvent. Make sure the
bearings are in good operating condition. Clean the in-
side of the wheel hub. Check the bearing cups for wear,
pitting or other damage. Replace worn or damaged
parts.
7. If wheel stud (item 13) removal is necessary, use
press to extract stud(s) from wheel hub.
8. If necessary, remove four (4) cap screws (item 3) that
secure spindle to steering fork assembly and remove
spindle.
Assembly (Fig. 18)
1. If spindle was removed from steering fork assembly,
apply Loctite #271 (or equivalent) to threads of cap
screws (item 3). Secure spindle to steering fork with four
(4) cap screws. Torque cap screws from 67 to 83 ft- -lb
(91 to 112 N- -m).
2. If bearing cups were removed from the wheel hub,
press new cups into the hub until they seat against the
shoulder of the hub.
3. If any wheel studs were removed wheel hub, use a
press to install new studs into hub. Make sure that stud
shoulder is fully pressed against hub surface.
4. Pack both wheel bearing cones with grease.

5. Install one greased bearing into the bearing cup on
inboard side of the wheel hub.
IMPORTANT: The lip of the seal must be toward the
bearing. The seal should be pressed in so it is flush
with the end of the wheel hub.
6. Lubricate the inside of a new seal (item 4) and press
it into the wheel hub with the seal lip toward the bearing.
7. Fill wheel hub cavity between bearings approximate-
ly 50% full of grease. Position remaining greased bear-
ing into the outer bearing cup.
8. Slide the wheel hub assembly onto the spindle shaft
and secure it in place with the spindle washer and jam
nut. DO NOT fully tighten the nut or install the cotter pin.
9. While rotating the wheel hub by hand, torque the jam
nut from 75 to 100 in-lb (8.5 to 11.3 N--m) to set the bear-
ings. Then, loosen the nut until the hub has endplay.
10.While rotating the wheel hub by hand, torque the jam
nut from 15 to 20 in-lb (1.7 to 2.3 N- -m). After tightening,
make sure that the wheel hub does not have any free
play.
11. Install nut retainer with slot aligned to cotter pin hole
in spindle. Install cotter pin.
12.Fill dust cap approximately half full of grease. Install
dust cap.
13.Install front wheel (see Wheel Installation in this sec-
tion).
14.Lower machine to ground.
Failure to maintain proper wheel lug nut torque
could result in failure or loss of wheel and may re-
sult in personal injury.
15.Torque lug nuts evenly in a crossing pattern from 75
to 85 ft- -lb (102 to 115 N- -m).
