-32-Removing
Tire and Tube
in well of rim at bottom. Insert tool between
bead and rim flange at top side of wheel and
pry wheel out of tire. See figure 6-32, view C.
3. Inspect inside of tire and remove any dirt
or other foreign materials. Inspect for cracks
in casing
which
wou
ld
pinch the
tube.
4. Insert the deflated tube in tire and inflate
just enough to round it out, placing valve at
red balance mark.
5. Make solution using water with tube mou
nt -
ing compound or prepared liquid tire
soap,
and
work it into a heavy suds. With a cloth or
sponge, swab thoroughly all around the base of
the
tube,
between the tube and beads of tire
and on the face of the
beads.
See figure 6-33,
view A. Do not us
e oil
or
greas e.
6. The soap acts as a lubricant and reduces
the friction as the tube passes over the beads
down into the well of the rim when inflat
ed.
If
tube and t
ire
are not properly
lubricated,
friction will prevent
tube
from sliding into the
well
of rim,
consequently
the tube will be
stretched thin in
t
his area when inflated. See
figure 6-33, views Band
C.
7.
Lay
wheel
flat with valve hole up. Start
to mount
tire
with
valve
pointing toward valve
hole.
Apply the
first bead by pushing a portion
of it into
the well
and
then
working the re-
maining
part over
the
flange
with a tire tool.
Spread
the
tire and
place
valve stem through
the
hole in rim. The us
e
of a valve fishing tool
or valve extension will aid in pulling
the
valve
into position.
8.
Force the
portion
opposite
the valve down
into the
well
of the rim and with
tire
tools
work the
remainder
of
the
bead
over the
flange,
alternating
from right t
o left
to
prevent
the
tire
from
creeping
on
the
rim. Make certain
~
that
the
beads
are out of the well and in posi-
tion to seat properly against
the
flange, then
pull the valve out so as to hold the base snugly
against the rim.
While
holding
the
valve in this
position, inflate the
tire
until both beads are
seated, with
the
centering ribs (when marked
on the tire) showing evenly above the rim
flange.
