COMPONENT PARTS
General Notes
The instructions here are organized so that you work on only one component group at a time.
This will help avoid confusion from similar-looking parts of different subassemblies being on
your workbench at the same time.
The component groups are inspected and repaired from the converter housing side.
As much as possible, complete the inspection, repair and assembly before proceeding to the
next component group. If a component group can not be assembled because parts are being or-
dered, be sure to keep all parts of that group in a separate container while proceeding with disas-
sembly, inspection, repair and assembly of other component groups.
Recommended fluid for the automatic transaxle: A540E ATF DEXRON II
A540H ATF Type T or equivalent
Recommended oil for the transfer: Transaxle oil E50, API GL5, SAE 75W-90 or equivalent
GENERAL CLEANING NOTES:
1. All disassembled parts should be washed clean, with any fluid passages and holes blown
through with compressed air.
2. When using compressed air to dry parts, always aim away from yourself to prevent acciden-
tally spraying automatic transaxle fluid or kerosene in your face.
3. The recommended automatic transaxle fluid or kerosene should be used for cleaning.
PARTS ARRANGEMENT:
1. After cleaning, the parts should be arranged in proper order to allow efficient inspection,
repairs, and reassembly.
2. When disassembling a valve body, be sure to keep each valve together with the corre-
sponding spring.
3. New brakes and clutches that are to be used for replacement must be soaked in transaxle
fluid for at least fifteen minutes before assembly.
GENERAL ASSEMBLY:
1. All oil seal rings, clutch discs, clutch plates, rotating parts, and sliding surfaces should be
coated with transmission fluid prior to reassembly.
2. All gaskets and rubber O-rings should be replaced.
3. Make sure that the ends of a snap ring are not aligned with one of the cutouts and are
installed in the groove correctly.
4. If a worn bushing is to be replaced, the subassembly containing that bushing must be re-
placed.
5. Check thrust bearings and races for wear or damage. Replace if necessary.
6. Use petroleum jelly to keep parts in place.

REMOVE NO. 2 SPEED SENSOR
(a) Disconnect the connector.
(b) Remove the bolt and pull out the speed sensor.
(c) Remove the O-ring from speed sensor.
9. (A540H)
REMOVE VEHICLE SPEED SENSOR
(a) Remove the bolt and pull out the speed sensor.
(b) Remove the O-ring from speed sensor.
10. REMOVE OIL PAN AND GASKET
(a) Remove the seventeen bolts.
(b) Remove the oil pan by lifting transaxle case.
NOTICE: Do not turn the transaxle over as this will
contaminate the valve body with the foreign materials
in the bottom of the oil pan.
(c) Place the transaxle on wooden blocks to prevent
damage to the oil tube bracket.
11. EXAMINE PARTICLES IN PAN
Remove the magnet and use it to collect any steel chips.
Look carefully at the chips and particles in the oil pan
and on the magnet to anticipate what type of wear you
will find in the transaxle.
Steel (magnetic)... bearing, gear and plate wear
Brass (non-magnetic)... bushing wear

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.

(b) Place SST on the spring retainer, and compress
the return spring with a shop press.

(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)

(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.)

Using a dial indicator (long type pick or SST), measure
the forward clutch piston stroke applying and releasing
the compressed air (4 - 8 kg/cm
2, 57 - 114 psi, 392 -
785 kPa) as shown.

(e) Tighten the O±ring fittings or the bolted type fittings to
the specified torque.
4. WHEN CONNECTING MANIFOLD GAUGE;
(a) Be sure to connect the charging hose end with a pin
to the compressor charging valve.
(b) The letter ºDº engraved near the compressor service
valve indicates the high pressure side, and ºSº indi-
cates the low pressure side. Pay careful attention
when connecting the hose.
(c) Tighten hose by hand.
(d) To prevent loosening of connected hose, do not apply
drops of compressor oil to the seat of connection.
HINT: After connecting the manifold gauge and the refrig±
erant container (service can), discharge any air in the
hoses.
5. WHEN EVACUATING;
Approx. 15 minutes after removal, check the system for
leaks, then take at least another 15 minutes to make sure
the air is fully removed.
6. WHEN HANDLING REFRIGERANT CONTAINER
(SERVICE CAN);
(a) Must never be heated.
(b) Must be kept below 4
°C (1 04°F).
(c) If warming service can with hot water, be careful that
the valve on top of the service can is never immersed
in the water, as the water may permeate into the refrig-
erant cycle.
(d) Empty service cans must never be re±used.
7. WHEN A/C IS ON AND REFRIGERANT GAS IS
BEING REPLENISHED;
(a) If there is not enough refrigerant gas in the refrigerant
cycle, oil lubrication becomes insufficient and com-
pressor burnout may occur, so take care to avoid this.
(b) If the valve on the high pressure side is opened, refrig-
erant flows in reverse and causes the service can to
rupture, so only open and close the vlave on the low
pressure side.
(c) If the service can is inverted and refrigerant is inserted
in a liquid state, the liquid is compressed and the com-
pressor brakes down, so the refrigerant must be in-
serted in a g¿¿seous state.
(d) Be careful not to insert too much refrigerant gas, as
this causes trouble such as inadequate cooling, poor
fuel economy, engine overheat, etc.
8. WHEN USING GAS±CYLINDER TYPE LEAK
DETECTION INSTRUMENT;
(a) As a naked flame is used, first make sure that there are
no flammable substances nearby before using it.
(b) Be careful, as poisonous gas is produced when
refrigerant gas comes in contact with heat parts.
