4) Blow air into fluid hole in O/D case (2) and remove brake pis-
ton (1).
5) Remove brake piston inner ring and brake piston outer ring
from brake piston.
6) Unsnap seal ring (1).
7) Remove 2 seal rings (1).

DISASSEMBLY
1) After removing retaining ring (1), remove direct clutch input
hub (2) and forward clutch hub (3).
2) Remove bearing race and thrust bearing.
3) Install direct clutch input hub (1) and retaining ring (2).
4) Install forward clutch (2) to O/D case (1). Apply 4 – 8 kg/cm
2
air pressure into fluid hole at the right of cut in O/D case and
measure movement of forward clutch piston.
If measured value is not within standard range, use either
1.8 mm (0.071 in.) or 2.0 mm (0.079 in.) clutch disc to adjust
it to standard value.
Standard forward clutch piston movement :
1.40 – 1.70 mm (0.056 – 0.067 in.)
1. Thrust bearing No. 2
2. Thrust forward clutch bearing
3. Thrust rear race

5) Remove retaining ring (1) and then remove direct clutch
input hub.
6) Remove retaining ring and then remove all clutch discs.
7) Using special tool and hydraulic press, compress forward
clutch piston return spring and remove retaining return
spring.
Special tool
(A) : 09926-98310
8) Remove forward clutch piston return spring.
9) Install forward clutch to O/D case. Blow low pressure air into
fluid hole at the right of cut in O/D case to remove forward
clutch piston.
CAUTION:
Be careful when applying pressure, for overpressure will
cause plate section of piston return spring to deform.

DIRECT CLUTCH
DISASSEMBLY
1) Install direct clutch assembly (1) to center support (2) and
with 4 – 8 kg/cm
2 air pressure applied to second fluid hole
from the left, measure stroke of direct clutch piston as shown
in figure.
If it is not within standard range, use 3.55 mm, 3.75 mm or
4.0 mm (0.140 in., 0.147 in. or 0.157 in.) clutch backing plate
to adjust it to standard stroke.
Standard direct clutch piston stroke :
0.90 – 1.30 mm (0.035 – 0.051 in.)
2) Remove direct clutch assembly from center support and
then remove retaining ring.
3) Remove clutch backing plate (1) and then remove clutch
disc (3) and clutch plate (2).
4) Using special tool and hydraulic press (1), compress direct
clutch piston return spring (3) and remove retaining return
spring ring (2).
Special tool
(A) : 09926-98310
5) Remove direct clutch piston return spring.
CAUTION:
Be careful when applying pressure, for overpressure will
cause plate section of piston return spring to deform.
