Remove the cassette housing control assembly.
2.
Place the mechanism in the stop mode by
unplugging the power cord in the fast forward
or rewind mode.
3.
Slowly rotate the torque gauge in the clockwise
(CW) direction and counterclockwise (CCW)
direction of the supply brake so that the reel disk
and the indicator of the torque gauge rotate at
an equal rate. Check that the values are within
the range of CW direction = 280 to 720 g-cm,
CCW direction = 90 to 230 g-cm, and that the
brake torque in the CW direction is at least twice
as high as that in the CCW direction.
Checking the brake torque at the take-up side
Adjust the Idler
gear in the center.

2.
Slowly rotate the torque gauge in the clockwise
(CW) direction and counterclockwise (CCW)
direction of the take-up brake so that the reel
disk and the indicator of the torque gauge
rotate at an equal rate. Check that the values
are within the range of CCW direction = 280 to
720 gem, CW direction = 90 to 230 g-m, and that
the brake torque in the CCW direction is at least
twice as high as that in the CW direction.

Adjustment of the brake torque at the supply
side and the take-up side
1. If the supply or take-up brake torque is outside
the range, clean the supply or take-up reel disk
break lever felt, then recheck the torque.
2. If the supply or take-up brake torque is still
outside the range, replace the main brake or the
main brake spring.
REPLACEMENT OF MAIN BRAKE
1. Remove the reel belt and the reel block FFC.
2. Remove the cut washer 0 off the brake shifter.
3. Unscrew the four screws C3 and then the take-
up reel retainer.
4. Remove the reel block assembly @ downward.
pulley.
6. Unscrew the two screws @ and detach the idler
assembly.
7. Unhook the back tension lever spring ($9 and
remove the back tension lever @. (Undo the
hook under the reel chassis.)
8. Open the shifter latch 63 and remove the brake
shifter assembly ED.
9. Release the reel disk catches Oand then remove
the left and right reel disk assemblies GD and 0.
10. Finally remove the main brake levers
main brake spring 0.
Note :
When the main brake is replaced, perform the
height checking and adjustment (see page l7),
and the brake torque checking (see page 22).
