2. Assemble the hub and rotor onto the spindle
with the rotor inboard ( Figure 42 ).
3. Assemble the outboard bearing onto the spindle
and seat the bearing to the outboard race
( Figure 42 ).
4. Assemble the tab washer onto the spindle
( Figure 42 ).
5. Thread the spindle nut onto the spindle and
tighten the nut to 15 N∙m (1 1 ft-lb), while rotating
the hub to seat the bearing ( Figure 42 ).
6. Loosen the spindle nut until the hub rotates
freely .
7. T orque 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 43 ).
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 43 ).
10. Install the dust cap onto the hub ( Figure 43 ).
1 1. 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 ange-head bolts (3/8 x 3/4 inch) and
apply a coat of medium-strength thread-locking
compound to the threads of the bolts.
2. Align the brake pads to either side of the rotor
( Figure 38 ) and the holes in the caliper bracket
with the holes in the brake mount of the spindle
frame ( Figure 42 ).
3. Secure the caliper bracket to the spindle frame
( Figure 38 ) using the 2 ange-head bolts (3/8
x 3/4 inch).
T orque the 2 ange-head 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 37 ).
Note: Ensure that the mounting surface of the
wheel is ush with the hub.
5. Secure the wheel to the hub using the lug nuts
( Figure 37 ).
T orque the lug nuts to 108 to 122 N∙m (80 to 90
ft-lb).
6. Repeat steps 1 through 5 for the brake and
wheel on the other side of the machine.
