TIRE
BALANCE.
(Refer
to
Figure
2-9a.)
Proper
balancing
is
critical
for
the
life
of
aircraft
tires.
If
a
new
tire
is
balanced
upon
installation
it
will
usually
remain
balanced
for
the
life
of
the
tire
without
having
any
shimmy
or
flat
spots,
and
an
inexpensive
balancer
can
be
made
that
will
balance
almost
any
tire
for
light
aircraft.
Balance
the
tire
as
follows:
a.
Mount
the
tire
and
tube
(if
one
is
used)
on
the
wheel,
but
do
not
install
the
securing
bolts.
Install
the
wheel
bearings
in
the
wheel;
then,
using
the
-7
bushings,
-6
spacers,
and
-5
nuts,
install
the
wheel-tire
assembly
on
the
-8
pipe.
Secure
the
-5
nuts
finger-tight
so
that
the
wheel
halves
touch
each
other.
Be
sure
the
bolt
holes
are
aligned!
Insert
the
-4
axle
through
the
-8
pipe
and
place
the
wheel
in
the
center
of
the
balancer.
Make
sure
the
axle
is
only
on
the
chamfered
edges
of
the
balancer
and
that
it
is
at
90
°
to
the
sides
of
the
balancer.
b.
Release
the
tire.
If
it
is
out
of
balance
it
will
rotate,
coming
to
rest
with
the
heaviest
point
on
the
bottom.
Tape
a
1/2
ounce
patch
across
top
center
of
the
tire.
Rotate
the
tire
45and
release
it
again.
If
the
tire
returns
to
the
same
position,
add
a
1
ounce
patch
and
again
rotate
the
tire
and
release
it.
Continue
this
procedure
until
the
tire
is
balanced.
c.
When
balance
is
attained,
put
a
chalk
mark
on
the
sidewall
directly
below
the
patch.
Use
one
mark
for
each
half
ounce
of
weight
needed.
Mark
the
valve
stem
location
on
the
tire
and
the
opposite
wheel
half
to
assure
reassembly
in
the
same
position.
Remove
the
wheel
from
the
balance
stand,
break
it
down
and
clean
the
inside
of
the
tire
with
toluol.
Apply
a
coat
of
patch
cement
to
both
the
patch
and
the
inside
center
of
the
tire
in
line
with
the
chalk
marks.
When
the
cement
has
dried,
install
the
patches
making
certain
they
are
on
the
center
line
of
the
tire
and
aligned
with
the
chalk
marks
on
the
sidewall.
Burnish
the
patches
to
remove
trapped
air,
etc.
d.
When
reassembling
the
wheel,
powder
the
inside
of
the
tire.
Mount
the
tire
on
the
valve
side
of
the
wheel
in
the
same
position
it
was
in
when
it
was
balanced.
Install
the
other
wheel
half,
aligning
the
chalk
marks.
Install
the
bolts
and
tighten
to
required
torque,
then
air
the
tire
and
recheck
balance.
The
wheel
should
not
be
more
than
1/2
ounce
out
of
balance..
e.
The
following
instructions
will
help
in
building
the
balancer:
(Refer
to
Figure
2-9a.)
1.
Chamfer
top
edges
of
-3
sides
leaving
1/16
inch
flat
on
top
inboard
edge.
Rivet
-2
tee's
to
-3
sides
using
AN
470-AD5
rivets
2"
spacing.
Use
AN
426-AD5
rivets
2"
center
to
center
to
secure
-2
tee's
to
-1
base.
If
tee
extrusion
is
unavailable,
heavy
angle
extrusion
could
be
used.
-3
sides
must
be
vertical.
2.
The
-4
axle
must
slide
through
the
-8
pipe.
The
-5
nuts
were
made
by
reaming
the
existing
threads
in
the
AN
365-624
nuts
with
an
R
drill,
then
tapping
with
a
1/8-27
pipe
tap.
3.
The
-6
spacers
were
made
from
1/2
inch
aluminum
tubing.
The
two
lengths
of
spacers
are
suitable
for
balancing
most
any
aircraft
wheel.
4.
The
-7
bushings
may
be
made
from
one
inch
Richlite
using
a
1
1/2 inch
hole
saw
to
cut
out
the
smaller
bushing
and
1
3/4 hole
saw
to
cut
out
the
larger.
By
inserting
a
1/4
inch
long
threaded
bolt
through
the
pilot
hole
and
securing
with
a
washer
and
nut,
a
drill
press
and
file
may
be
used
to
make
the
off-set
on
the
bushing.
The
turned-down
part
should
just
slide
inside
the
bearing
race.
Ream
the
pilot
hole
to
slide
over
the
-8
pipe
threads.
5.
The
-8
pipe
was
made
from
a
piece
of
1/8
inch
black
pipe
and
threaded
with
a
1/8-27
pipe
die.
Thread
3
inches
from
each
end
of
the
pipe.
