REAR COVER (O/D BRAKE PISTON ASSEMBLY)
DISASSEMBLY
1) Remove O/D brake piston (1) from rear cover (2).
2) Remove O-ring (3) and seal ring (4).
Replace them, if damaged.
ASSEMBLY
1) Install seal rings to rear cover and O-rings to O/D brake pis-
ton.
2) Apply grease to O-rings and install O/D brake piston to rear
cover.
PLANETARY SUN GEAR NO.1 ASSEMBLY
DISASSEMBLY
1) Remove one-way clutch retainer (1) from planetary sun gear
No.1 assembly.
2) Remove one-way clutch bearings (2), one-way clutch (3),
inner race (4) and washer (5) from planetary sun gear No.1
(6).
ASSEMBLY
Reverse removal procedure noting followings.
When installing retainer, fit 2 hooks of retainer on planetary
sun gear No.1 and tap the other 2 hooks with plastic ham-
mer.
After assembling, make sure that :
There is no clearance between retainer and bearing. NOTE:
If O/D brake piston is hard to take it out, force low-pres-
sure compressed air (1 kg/cm
2, 15 psi, 100 kPa max) into
hole (5) shown in figure and pop out piston into a rag.
NOTE:
Do not reuse retainer.

2) Install new oil seal to transmission case.
Use special tool to press-fit oil seal until oil seal end face is
flush with transmission case end face.

UNIT ASSEMBLY
CAUTION:
 Automatic transmission consists of highly precise parts. As even a flaw in a small part may cause
oil leakage or decrease in function, check each part carefully before installation.
 Clean all parts with compressed air. Never use wiping cloths or rags.
 Before assembling new clutch discs and brake band, soak them in automatic transmission fluid for
at least 2 hours.
 Be sure to use new gaskets and O-rings.
 Lubricate O-rings with automatic transmission fluid.
 Apply automatic transmission fluid on sliding or rotating surfaces of the parts before assembly.
 Use yellow petrolatum grease or Suzuki Super Grease C to retain parts in place.
 Be sure to install thrust bearings and races in correct direction and position.
 Make sure that snap ring ends are not aligned with one of cutouts and are installed in groove cor-
rectly.
 Do not use adhesive cements on gaskets and similar parts.
 Be sure to torque each bolt and nut to specification.

19) Measure the clearance of O/D brake (B0) in the following
manner.
Blow compressed air into hole (4) shown in figure to activate
1st & 2nd brake (B1) piston, then measure the distance
between the top of O/D brake (B0) plate and the transmis-
sion case – rear cover mating surface.
Call this value (A).
((A) = The value on vernier caliper – width of straight edge )
Measure the distance from top of O/D brake (B0) piston (on
rear cover) to rear cover – transmission case mating surface.
Call this value (B).
Clearance = (A) – (B) + 0.4
O/D brake (B0) clearance
Standard : 0.80 – 1.40 mm (0.0315 – 0.0551 in.)
20) If the obtained value is out of standard value, replace brake
disc and plate.
