Adfustrnent, Trouble Shooting and Maintenance
When replacing the
wheels,
they
should be
carefully
centered between the
forks
and brakes. Be certain that wheel nuts
are
replaced while all
spokes
should
be adequately tightened. When the gear shift operating cable connector
is re-
assemblcd, recheck its setting
as
described
in Sec. 6.3.1 3.
Wheels should be regularly
checked
for "wobbling" from
side
to
side,
and
"hop"-
being
out of
round or
of
unequal diameters.This misalignment can
be
detected bcst
by
turning the bicycle upside down, rotating the wheel while
using
our
finger or a pencil placed next to the rim
as a
guide.
Severe
misalign-
ment
will
causc
the tire to intermittently rub
against
the fork, or the rim
against
the brake shoe.
Warning: Whccl misalignment
will
lead
to grabbing or failure of
braking
power,
and should
be
corrected at once.
To correct this
problem,
first
check the
rim to
make sure
it
is
not
dented
or
twisted.
lf it
is,
take the wheel to
a
dealer
for
specialized repair or replacement.
Uneven spoke
tension,
or
missing,
bent or broken
spokes,
will
also cause the
