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).

5A-120 Automatic Transmission/Transaxle: 

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).
