4.3 CLUTCHES
The motor torque is transferred to the turntables by
means of the friction discs and the felt ring which is
glued on to the bottom side of the turntables. The
amount of friction is determined by the clutches
which are operated by the operating arm 248186. The
operating arm is linked with the operating lever
990225.
4.3.1 Neutral
See fig. 4.15.
The motor current is switched off by the switch
202151 and both friction discs 209658 are stationary.
Supply turntable 990226
In position neutral, the friction between the turntable
and the friction disc 209658 is at maximum. The fric-
tion disc is pressed against the felt ring underneath
the turntable by the spring 218415. The operating arm
248186 is in a position that allows the delrin knob on
the lever 990228 to rest in the lower position. The
delrin studs on the bushing 202230 are disengaged
from the clutch lever.
Adjustment:
Adjust screw A until the spacing between the lever
and delrin studs on the bushing is 0.5-1 mm (20-40
mil). Check the lever position in all operating modes
and seal screw A.
Take-up turntable (990227) ,fig. 4.16
When the operating lever is in position neutral, maxi-
mum friction exists between the friction discs 209658
and the take-up turntable. The friction disc is pressed
against the felt ring underneath the turntable by the
spring 218415, and by the spring loaded lower clutch
lever 202740 which exerts pressure against the del-
rin bushing 202230 from underneath. The operating
arm 248186 is in a position so as to leave the delrin
knob on the upper clutch lever 990229 in the lower
position.
Adjustment:
Adjust screw B until the spacing between upper and
lower clutch levers is approx. 0.5 mm (20 mil). Check
the lever position in all operating modes and seal
screw B.
