Overdrive (Case Side) Disassembly and
Assembly

S6JB0A5106037

Disassembly

1) Remove retaining ring (1), brake backing plate (2),

brake disc (3) and brake plate (4) in that order. Then
remove planetary ring gear, thrust bearing race and
thrust bearing.

2) Remove retaining ring and piston return spring using

special tool and press (1).

Special tool
(A): 09926–96510

CAUTION

!

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

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

,

57 – 113 psi) to oil hole (1) in O/D case (2) and
remove brake piston.

4) Remove brake piston inner ring and brake piston

outer ring from brake piston.

5) Unsnap seal ring (1).
6) Remove 2 seal rings (1).

NOTE

5A-117 Automatic Transmission/Transaxle:

Assembly
Install each component by reversing removal procedure
and noting the following points.
• When installing rear seal ring, use care not to open it

too wide.

• Apply A/T fluid to O-ring, disc, etc. before installing

them.

• Opening of retaining brake front ring (2) and

projection (1) of O/D case should be matched.

• When installing each component, refer to “Overdrive

(Case Side) Components”.

• Measure clearance between retaining ring (1) and

brake backing plate (2) with thickness gauge.
If the clearance is out of specification, select another
plate with suitable thickness from the list below and
replace it.

Standard clearance between retaining ring and
brake backing plate
0.40 – 1.38 mm (0.016 – 0.054 in.)

Overdrive (Case Side) Inspection

S6JB0A5106038

• Measure free length of piston return spring.

Standard free length of O/D brake piston return
spring
15.10 mm (0.594 in.)

• Check that sliding surface of discs and plate are not

worn or burnt. If necessary, replace them.

NOTE

• If disc lining is exfoliated, discolored or

worn hardly, replace all discs.

• If only a part of printed numbers is

corroded, replace all discs.

• Before assembling new discs, soak them

in A/T fluid for at least 15 minutes.

Thickness

1.95 – 2.05 mm (0.077 – 0.081 in.)
2.25 – 2.35 mm (0.089 – 0.093 in.)
