2. Assemble the hub and rotor onto the spindle
with the rotor inboard (
Figure 29 ).
3. Assemble the outboard bearing onto the spindle
and seat the bearing to the outboard race
(
Figure 29 ).
4. Assemble the tab washer onto the spindle
(
Figure 29 ).
5. Thread the spindle nut onto the spindle and
tighten the nut to 15 N∙m (11 ft-lb), while rotating
the hub to seat the bearing (
Figure 29 ).
6. Loosen the spindle nut until the hub rotates
freely.
7. Torque the spindle nut to 170 to 225 N∙cm (15
to 20 in-lb).
8. Install the retainer over the nut and check the
alignment of the slot in the retainer and the hole
in the spindle for the cotter pin (
Figure 30 ).
Note:
If the slot in the retainer and the hole in
the spindle are not aligned, tighten the spindle
nut to align the slot and hole to a maximum
torque of 226 N∙cm (20 in-lb) on the nut.

9. Install the cotter pin and bend each legs around
the retainer (
Figure 30 ).
10. Install the dust cap onto the hub ( Figure 30 ).
11. Repeat steps 1 through 10 for the hub and rotor
at the other side of the machine.
Installing the Brakes and Wheels
1. Clean the 2 flange-head bolts (3/8 x 3/4 inch)
and apply a coat of anti-seize compound to the
threads of the bolts.
2. Align the brake pads to either side of the rotor
(
Figure 25 ) and the holes in the caliper bracket
with the holes in the brake mount of the spindle
frame (
Figure 29 ).
3. Assemble the caliper bracket to the spindle
frame (
Figure 25 ) with the 2 flange-head bolts
(3/8 x 3/4 inch), and torque the bolts to 47 to 54
N∙m (35 to 40 ft-lb).
4. Align the holes in the wheel to the studs of the
hub and assemble the wheel to the hub with the
valve stem outward (
Figure 24 ).
Note:
Ensure that the mounting surface of the
wheel is flush with the hub.
5. Secure the wheel to the hub with the lug nuts
(
Figure 24 ), and torque the nuts to 108 to 122
N∙m (80 to 90 ft-lb).
6. Repeat steps 1 through 5 for the brake and
wheel at the other side of the machine.
