Remove the cassette housing control assembly.
Place the mechanism in the stop mode by
unplugging the power cord in the fast forward
or rewind mode.
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
CCW direction
90 to 230
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
gear
the center.

Figure l-44.
Remove the cassette housing control assembly.
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
CW direction
90 to 230
and that
the brake torque in the CCW direction is at least
twice as high as that in the
direction.
l
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
off the brake shifter.
3. Unscrew the four screws
and then the
up reel retainer.
4. Remove the reel block assembly
downward.
Remove the cut washer
then the reel
pulley.
6. Unscrew the two screws
and detach the idler
assembly.
7. Unhook the back tension lever spring
and
remove the back tension lever
(Undo the
hook under the reel chassis.)
8. Open the shifter latch
and remove the brake
shifter assembly
9. Release the reel disk catches
then remove
the left and right reel disk assemblies
and
10. Finally remove the main brake levers
main brake spring
Take-up

Note
When the main brake is replaced, perform the
height checking and adjustment (see page
and the brake torque checking (see page 22).
