Center Support Disassembly and Assembly

S5JB0A5106084

Disassembly

1) Remove retaining ring.

Special tool
(A): 09920–76010

2) Pull out center support assembly (2) from planetary

sun gear (1).

3) Apply compressed air (400 – 800 kPa, 4 – 8 kg/cm

2

,

57 – 113 psi) to oil hole (1) at the extreme left and
measure movement of second coast brake (Second
coast brake) piston.
If measured value is not within standard range,
replace second coast brake plate or second coast
brake disc.

Standard second coast brake piston movement
0.75 – 1.35 mm (0.030 – 0.053 in.)

4) Remove retaining ring.

5) After removing clutch backing plate (1), remove

second coast brake plate (3) and second coast
brake disc (2).

6) Using special tool and hydraulic press, compress

piston return spring and remove snap ring.

CAUTION

!

Be careful when applying pressure, for
overpressure will cause plate section of
piston return spring to deform.

Special tool
(A): 09926–98310

7) Remove brake piston return spring (1).

8) Apply compressed air (400 – 800 kPa, 4 – 8 kg/cm

2

,

57 – 113 psi) to oil hole at the extreme left and
remove second coast brake piston as shown in the
figure. Then remove piston inner O-ring and piston
outer O-ring from second coast brake piston.

9) Remove 3 seal rear rings (1).

NOTE
Use care not to open ring more than
necessary.

10) Apply compressed air (400 – 800 kPa, 4 – 8 kg/cm

2

,

57 – 113 psi) to second hole (1) from the left and
measure stroke of second brake (Second brake)
piston as shown in the figure.
If measured value is not within standard range,
replace second brake plate or second brake disc.

Standard second brake piston stroke
0.97 – 1.70 mm (0.038 – 0.067 in.)

11) After removing retaining back plate ring, remove

clutch backing plate, second brake plates and
second brake discs.

12) Using special tool and hydraulic press, compress

brake piston return spring and remove snap second
coast brake ring.

CAUTION

!

Be careful when applying pressure, for
overpressure will cause plate section of
piston return spring to deform.

Special tool
(A): 09926–98310

13) Remove brake piston return spring.

14) Blow air into the second air hole from the left and

remove second brake piston. Then remove piston
inner O-ring and piston outer O-ring from second
brake piston.

15) With second brake hub assembly (3) held stationary,

turn planetary sun gear (4) clockwise to check that it
locks and then counterclockwise to check that it
turns smoothly.

16) Remove second brake hub assembly (1) from

planetary sun gear (2).

17) Remove 2 sun gear seal rings (1) from planetary sun

gear.

NOTE
Use care not to open sun gear seal ring more
than necessary.

Assembly

Assemble components by reversing disassembly
procedure and noting the following points.
• Snap both ends of sun gear seal ring (1) securely.

• Do not open sun gear seal ring more than necessary.
• Always use new O-ring and apply A/T fluid before

installation.

• When installing O-ring, make sure that it is not kinked

or caught.

• Push in brake piston horizontally.
• When installing brake piston return spring, be careful

so that spring will not fall or tilt.

• When installing snap ring, do not align lug (1) of

retainer with opening in snap ring (2).
