4.3.2 Normal Forward Drive
Supply turntable. Fig. 4.17.
The supply turntable is free in normal forward drive
mode. The delrin knob on the clutch lever
990228
is
held in upper position by the operating lever
248186.
The delrin bushing
202230
and the friction disc
209658
are pressed down.
Adjustment:
Adjust screw
A
until the spacing between the friction
disc and the felt ring underneath the turntable is
between 0.5 and 1 mm (20-40 mil). Check clutch
lever positions in all operating modes, and seal
screw
A.
Take-up turntable. Fig. 4.18.
In normal forward drive the take-up turntable has a
winding torque which is just sufficient to wind the
tape in record or playback mode. The operating arm
holds the delrin knob on the lever in an intermediate
position. The upper clutch lever
990229
will press
down the lower clutch lever
202740
thereby releasing
the pressure of the friction disc against the turntable.
The friction disc is pressed against the turntable felt
ring by the spring
218415.
Adjustments:
By means of screw
B,
bring the studs of bushing
202230
to a position half-way between upper and
lower clutch levers. The winding torque should
amount to 120-200 g cm (1.7-2.8 oz. in). Check the
position of the levers in all operating models and seal
screw
B.
