Adjustment of Cassette Mechanism
Playback Torque
1. The playback torque should be within 45 to 70 g-cm.
2. If the torque is less than 45 g-cm, set the two-flat clutch
spring plate of the take-up reel disk to the 4 position.
If the torque exceeds 70 g-cm, set the spring plate to the
2 position.
Note: Before adjusting the torque wipe off the surface of
rubber parts and rotating parts, if the torque is not
sufficient.
No. 1409

Fast Forward & Rewind Torque
1. Fast Forward Torque
In the fast forward mode, check that the F.F. torque is
within 60 to 130 g-cm by applying the torque gauge to
the take-up reel.
2. Rewind Torque
In the rewind mode, check that the rewind torque is
within 60 to 130 g-cm by applying the torque gauge to
the supply reel.
Thrust of Flywheel
The clearance between the top of flywheel spindle and the
flywheel bracket should be within 0.1 to 0.3 mm.
If the clearance is out of limits, adjust the adjusting screw
for normal value.
Note: After adjustment, fix the screw with lock adhesive.
Adjusting Screw
0.1 ~0.3 mm

Location of Heads
The play/record and erase heads should be positioned as
shown below in the playback mode.

Pressure of Pinch Roller
1. Setting the mechanism vertically in the playback mode,
the pinch roller should stop turning at the pressure of
380~450 g when the pinch rcller arm has been pulled
upwards by tension gauge as shown in Fig. 11.
2. If the pressure is out of limit, change the pinch roller
spring.
Note: If the pressure is excessively high, it may cause
the noise from the pinch roller bearing and defec-
tive in wow and flutter. If the pressure is defective-
ly low, it may cause defective in auto stop motion
and in wow and flutter.

TAPE SPEED
1. The tape speed should be within 2940 Hz (—2%) to
3090 Hz (+3%) by reference tape.
2. If the speed is out of limit, adjust it by inserting the
small screw-driver into the adjusting hole of motor.
a. If the speed is less than --2% turn the driver clock-
wise.
b. If the speed is over +3%, turn the driver counter-
clockwise.
