6. RECHECK PISTON STROKE OF FORWARD CLUTCH
Set a dial indicator and measuring terminal (SST) togeth-
er, measure the forward clutch piston stroke while apply-
ing and releasing compressed air (392 ± 785 kPa, 4 ± 8
kgf/cm
2, 57 ± 114 psi).
SST 09350±32014 (09351±32190)
Piston stroke:
1.41 ± 1.82 mm (0.0555 ± 0.0717 in.)
If the piston stroke is less than the limit, parts may be mis-
assembled and reinstall them.
If the piston stroke is non±standard, select another
flange.
HINT: There are 5 different flange thickness.
Flange thickness:
2.8 mm (0.110 in.)
3.0 mm (0.118 in.)
3.2 mm (0.126 in.)
3.4 mm (0.134 in.)
3.6 mm (0.142 in.)

PLANETARY RING GEAR INSPECTION
1. INSPECT RING GEAR FLANGE BUSHING
Using a dial indicator, measure the inside diameter of the
flange bushing.
Standard inside diameter:
19.025 ± 19.050 mm (0.7490 ± 0.7500 in.)
If the inside diameter is greater than the maximum, re-
place the flange.
2. REMOVE RING GEAR FLANGE
(a) Using a screwdriver, remove the snap ring.
(b) Remove the flange from the ring gear.
3. INSTALL RING GEAR FLANGE
(a) Position the flange into the ring gear.
(b) Using a screwdriver, install the snap ring.

SECOND BRAKE INSPECTION
INSPECT DISCS, PLATES AND FLANGE
Check if the sliding surface of the discs, plates and flange
are worn or burnt. If necessary, replace them.
HINT:
If the lining of the disc is peeling off or discolored, or
even if a part of the printed numbers are defaced, re-
place all discs.
Before assembling new discs, soak them in ATF for
at least 15 minutes.
SECOND BRAKE PISTON ASSEMBLY
INSTALL PISTON
(a) Coat a new O±ring with ATF.
(b) Install the 2 O±rings on the piston.
(c) Press the piston into the drum, being careful not to dam-
age the O±rings.
