2. Assemble the hub and rotor onto the spindle with the
rotor inboard (Figure
3. Assemble the outboard bearing onto the spindle and
seat the bearing to the outboard race
4. Assemble the tab washer onto the spindle
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 (Figure
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.

in the brake mount of the spindle frame
3. Assemble caliper bracket to the spindle frame

torque the bolts 47 to 54 N∙cm (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
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
29), and torque the nuts to 108 to 122 N∙m (80 to 90
ft-lb).
6. Repeat steps
other side of the machine.
