5.4 ADJUSTING THE PINCH ROLLER PRESSURE
Measure the pressure of the pinch roller using a gauge as
shown. For measurement, draw the pinch roller in the
arrow direction in which it is detached from the capstan
shaft and gradually return it toward the capstan. Read
the gauge at the time when the pinch roller starts turning.
The standard pressure is 30050 g. If the pressure is out
of the range,
bend
the pinch roller spring aroung the
point A in the direction B or C.
5.5 ADJUSTING THE PLAY TORQUE
Mount the extended parts A (two) of the disc leaf spring
on any one of the stepping parts of the idler.
Adjusting range: 40 to 70 g.cm
NOTES:
(1) To increase
torque, mount
the extended
parts on
"INCREASE"
and to decrease torque, mount them on
"DECREASE".
(2) Check the take-up clutch for slipping. When the reel
base
is paused,
the wheel
must
smoothly
rotate. The
wheel, when
irregularly rotating or stopping, is not ac-
ceptable.
5.6
ADJUSTING THE FLYWHEEL THRUST
Adjust the thrust screw at the flywheel bracket until the
clearance
between
the capstan tail end and thrust bear-
ing is 0.1 to 0.3 mm
as shown,
using a phillips screw
driver. For adjusting, feel of axial dropping of the fly-
wheel
for proper
clearance
as this cannot
been
seen
through. Then paint the screw to lock.
