DISASSEMBLY OF DIRECT CLUTCH
1. CHECK PISTON STROKE OF DIRECT CLUTCH
(a) Install the direct clutch on the oil pump.
(b) Using a dial indicator (long type pick or SST),
measure the direct clutch piston stroke applying
and releasing the compressed air (4 - 8 kg/cm
2,
57 - 114 psi, 392 - 785 kPa) as shown.
SST 09350-32014 (09351-32190)
Piston stroke: A540E 0.91 - 1.35 mm
(0.0358 - 0.0531 in.)
A540H 1.11 - 1.47 mm
(0.0437 - 0.0579 in.)
If the piston stroke is greater than the maximum, inspect
each component.

INSPECTION OF DIRECT CLUTCH
1. INSPECT CLUTCH PISTON
(a) Check that the check ball is free by shaking the
piston.
(b) Check that the valve does not leak by applying
low-pressure compressed air.
2. INSPECT DISCS, PLATES AND FLANGE
Check if the sliding surfaces of the discs, plates and
flange are worn or burnt. If necessary, replace them.
HINT:

If the lining of the disc is exfoliated or discolored,
or even a part of the printed numbers are de-
faced, replace all discs.

Before assembling new discs, soak them in ATF
for at least fifteen minutes.
3. CHECK DIRECT CLUTCH BUSHING
Using a dial indicator, measure the inside diameter of
the direct clutch bushing.
Maximum inside diameter: 48.27 mm (1.9004 in.)
If the inside diameter is greater than the maximum, re-
place the direct clutch.
ASSEMBLY OF DIRECT CLUTCH
1. INSTALL CLUTCH PISTON IN DIRECT CLUTCH
DRUM
(a) Install new O-rings to the piston. Coat the O-rings
with ATF.
(b) Being careful not to damage the O-rings, press
the piston into the drum with the cup side up.
2. INSTALL PISTON RETURN SPRING
(a) Place the return spring and snap ring onto the
piston.

(c) Install the snap ring using snap ring pliers. Be
sure the end gap of snap ring is not aligned with
the spring retainer claw.
3. INSTALL PLATES, DISCS AND FLANGE
(a) Install plates and discs.
Install in order: P = Plate D = Disc
P-D-P-D-P-D
(b) Install the flange with the flat end facing downward.
4. INSTALL SNAP RING
Check that the end gap of the snap ring is not aligned
with one of the cutouts.
5. RECHECK PISTON STROKE OF DIRECT CLUTCH
(a) Install the direct clutch on the oil pump.
(b) Using a dial indicator (long type pick or SST),
measure the direct clutch piston stroke applying
and releasing the compressed air (4 - 8 kg/cm
2,
57 - 114 psi, 392 - 785 kPa) as shown.
SST 09350-32014 (09351-32190)
Piston stroke: A540E 0.91 - 1.35 mm
(0.0358 - 0.0531 in.)
A540H 1.11 - 1.47 mm
(0.0437 - 0.0579 in.)
If the piston stroke is nonstandard, select another
flange.
HINT: There are two different thicknesses for the
flange.
Flange thickness: 2.70 mm (0.1063 in.)
3.00 mm (0.1181 in.)
