WHEEL
MOUNTING
Nearly
all
standard
wheels
and
many
alloy
wheels
have
accurately
machined
center
holes,
and
they
should
be
mounted
with
center
cones.
Accurate
balancing
depends
on
accurate
mounting
of
the
wheel
and
correct
seating
of
the
cone
in
the
pilot
hole.
Insure
that
the
wheel
is
centered
on
the
shaft
exactly
as
it
will
be
mounted
to
the
vehicle.
Before
starting
any
balancing
procedure
it
is
very
important
that
the
wheel
is
mounted
on
the
machine
with
the
proper
adaptors.
An
incorrect
centering
of
the
wheel
will
result
in
considerable
imbalance.
There
are
many
types
of
wheels
and
Snap

supplies
adaptors
of
good
quality
and
durability
for
the
large
majority.
However
if
you
meet
special
wheels
which
may
require
a
specific
adaptor,
call
your
Snap
‐
on
franchise.

into
these
major
groups:
1.
