Instructions
|
|
|
First,
remove the nut holding the valve stem. |
 |
Push the bead of the tire loose
from the rim all the way around, on
both
sides. |
 |
So it falls loose from the rim
|
 |
Always start removing the tire at
the valve stem. Insert tire
iron
and carefully pry tire over rim while holding opposite hand down on
tire
to keep it in the center valley of the rim.
|
 |
The tire does not stretch- you must
get slack by having the tire bead
in
the lowered center portion of the rim to be able to pry it over on the
opposite side of the wheel. Here you can see my left thumb holding the
tire bead in the center, while the right pushes the tire iron
down. |
 |
While holding the first iron in
place, install the second as close as
possible
to the first, to pry over another "bite" |
 |
Repeat taking the smallest "bite"
at a time, all the while holding the
tire bead down into the center of the rim. |
 |
After the first few inches, the
rest of the bead should lift over quite
easily. |
 |
When the side is off the rim,
remove the tube. If
your
tire is in good shape, check the inside carefully for dirt or objects
sticking
in the tire. It is not required to completely remove the tire to
replace
the tube. |
 |
To finish removing the tire, insert
tire iron from the backside and
through
to the edge of the rim, then pry the tire over. |
 |
Keep the tire bead in the center of
the rim! |
 |
Move the tire irons apart while
prying to force the tire off the
rim |
 |
Or give it a few blows to speed up
removal |
 |
This is the dropped center of the
rim. All rims have this, unless they
are "split", and can be taken into two pieces.
|
 |
This is the tire "bead", there are
very stiff wires wrapped around here
to give strength to the bead, so it does not stretch and blow off the
rim. |
 |
This is a alignment line to make
sure the tire is centered properly on
the rim. It should be the same distance to the rim all the way
around. |
 |
To reinstall, set the tire over the
rim edge |
 |
And pry it on with an iron, then
hold the iron in place |
 |
While you use the other iron to get
another bite |
 |
When one side
is on, insert the tube,
putting the stem through the hole
first, then putting the nut on loosely. (about 1/2 way)
|
 |
Get the tube in all the way, be
sure it is not twisted or folded. |
 |
Push the tire down toward the
center, just to the side of the valve
stem.
When prying the tire over the rim, the valve can cause interference
with
the tire bead in the rim center, making it hard to pry the tire over.
The
area over the stem should be the last part pried over.
|
 |
Holding the tire down toward the
rim center with one hand, use the
other
to pry the tire over. This is a critical moment, when many times the
tube
is pinched and ruined. Note that when the tire iron is forced down the
tip of the iron is able to snag the tube inside and pinch it against
the
rim. You must avoid this by not pushing the iron down any further than
needed to get the tire over the rim. |
 |
Continue prying the tire over,
taking small bites, always keeping the
opposite
side bead pushed down into the center of the rim to allow slack.
|
 |
The last bit should be right over
the stem. This should be easily
pushed
on by hand. |
 |
The tube will try to get pinched in
here, between the tire and rim. Be
carefull! |
 |
The stem should be straight
when tire is inflated. Check around
the
rim/bead area to be sure the tire is centered properly.
|
Do
not
tighten
the stem nut with a wrench.
Finger
tight is ok. after inflating the tire, let the air out to allow the
tube
to relax and center itself in the tire. Then reinflate to proper
pressure.
|
| The
front
tire needs to be removed for
repair.
The axle must be removed to take out the wheel, take note of any
spacers
and the position of the speedometer cable drive. Replica Watches Use caution when
putting
the speedometer drive on the wheel when you are putting it back
together.
There is a tang sticking out on the drive that must be aligned with the
notch in the wheel that turns it. There may also be a tang that is
aligned
to the fork leg to keep the brake backing plate from spinning. |
