Suzuki Grand Vitara JB416 / JB420 / JB419. Manual — part 334

5A-127 Automatic Transmission/Transaxle:

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).

• When installing brake discs, brake plates and clutch

backing plate, refer to “Center Support Components”.

• Install clutch backing plate (1) with its flat side facing

brake disc.

• After installing each retaining backing plate ring,

measure movement of brake piston again.
If it is not within standard range, it is possible that ring
is not installed properly. Then disassemble and
reassemble again.

Standard movement of second coast brake piston
and second brake piston
Second coast brake piston: 1.00 – 1.20 mm (0.039
– 0.047 in.)
Second brake piston: 1.01 – 2.25 mm (0.040 –
0.089 in.)

Center Support Inspection

S6JB0A5106047

• 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.

• Measure inside diameter of center support hub

bushing. If inside diameter exceeds limit, replace
center support.

Center support bushing inside diameter standard
36.386 – 36.411 mm (1.4325 – 1.4335 in.)

• Measure inside diameter of planetary sun gear

bushing. If inside diameter exceeds limit, replace
planetary sun gear.

Planetary sun gear bushing inside diameter
standard
21.501 – 21.527 mm (0.8465 – 0.8475 in.)

• Measure free length of piston return spring.

Standard free length of second coast brake piston
return spring
16.84 mm (0.663 in.)

Standard free length of second brake piston
return spring
15.82 mm (0.623 in.)
