Adjustments
should
be undertaken
in
the
most efficient
manner,
as
suggested
below:
'l
.
Use test tapes and
measuring apparatus that are
new
(if possible)
and well
calibrated.
2. Check
first
that the tape
transport
mechanism
is
in
order.

etc.
b) Clean
the
belts,
flywheel, motor
pulley,
etc.,
and
check
for
rubbing
parts
or
marred
surfaces.
4.
Measure
the
wow;
if it
exceeds
the
specification, measure and adjust the
reel motor torque.
5. ln
most
cases, the
measured
wow/flutter
should meet the specification
by the
time
you
reach the 3rd
or 4th step above. lf
not,
a
faulty
pinch
roller, capstan or belt may
be
the
cause. and replacement is
called
for.
Usually
replacement
of
a motor should
not
be
considered;
should
the
motor be
suspect,
first apply oil
to its shaft
and
keep
it running
for
two
or three
hours, and
check
it again.
lnspecting the
reel motor
capacitor
may also reveal the
solution.
