2. Assemble the hub and rotor onto the spindle
with the rotor inboard
3. Assemble the outboard bearing onto the spindle
and seat the bearing to the outboard race
(Figure 37).
4. Assemble the tab washer onto the spindle
(Figure 37).
5. Thread the spindle nut onto the spindle and
tighten the nut while rotating the hub
Note:
Tighten the nut and rotate the spindle
until the bearings are fully seated and the hub
has no linear-end movement.
6. Loosen the spindle nut until the hub rotates
freely.
7. Torque the spindle nut to 170 N∙cm (15 in-lb)
while rotating the hub.
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
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.

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 33) and the holes in the caliper bracket
with the holes in the brake mount of the spindle
frame (Figure
3. Assemble the caliper bracket to the spindle
frame (Figure
(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
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 32), and torque the nuts to 108 to 122
N∙m (80 to 90 ft-lb).
6. Repeat steps
