WARNING
Figure 32-10: Installation - bearing race.
d) Push the bearing race fully into the wheel.
e) Remove the wheel from the press. Visually examine the race. Make sure that
it is fully and tightly installed in the wheel.
3 To install the tire on the wheel:
Make sure that the wheel is clean and dry to prevent accidents. The bead area must
be clean and dry without grease or other dirt. Grease or dirt decrease the friction
and can cause the tire to turn on the wheel, when the brakes are operated.
a) Put the inner tube into the tire. Align the red dot on the tire (its lightest
point) with the white or yellow dot on the tube (its heaviest point). If the
tube does not have a white dot, align the red dot on the tire with the valve
stem of the tube. We recommend that you apply a layer of talc powder to
the tube and the internal part of the tire. This will let the tube move easily
into the tire.
b) Inflate the inner tube to approximately 10 psi until it has the shape of the
tire. Release pressure from the tire. Stop to release the pressure, when the
tire starts to change its shape.
c) Put the tire and the tube onto the outer wheel half. Carefully put the valve
stem through the hole in the wheel half.
d) Install the inner wheel half into the tire. Make sure that the tie bolt holes are
aligned and that the tire is not between the two halves.
e) Put the wheel and the tire assembly on a flat work surface. The internal side
of the wheel must point up. Install the brake disc in the inner wheel half.
Align the bolt holes with the wheel half. Put the tie bolts through the brake
disc and the wheel.
f) Turn the wheel from the work surface on the opposite side to attach the
nuts to the tie bolts. Tighten a nut with washer on each of the tie bolts with
your hand. Make sure that the wheel halves touch each other but that the
inner tube is not between them.
g) Torque the tie bolt nuts to the value shown on the wheel label. The usual
torque values are 90 inch-pounds for 1/4" bolts and 150 inch-pounds for
5/16" bolts. Measure the torque value that is necessary to turn the nut
(locking friction of the nut). Add this value to the necessary torque values to
get the correct installation torque.
