(b) Using SST, measure the piston stroke applying and
releasing the compressed air (4 - 8 kg/cm2
57 -
114 psi or 392 - 785 kPa) as shown.

Piston stroke: 2.0 - 3.5 mm (0.079 - 0.138 in.)
If the piston stroke exceeds the limit, inspect the second
coast brake band (See page AT-41).
23. REMOVE SECOND COAST BRAKE PISTON
(a) Using SST, remove the snap ring.

(c) Remove the piston and outer return spring.
(d) Remove the two O-rings from the cover.

NOTICE: Before removing the oil pump, remove the
second coast brake piston.
(a) Remove the seven bolts.
(b) Using SST, pull out the oil pump from the transaxle
case.

(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.

COMPRESSOR
ON±VEHICLE INSPECTION
1. INSTALL MANIFOLD GAUGE SET
(See page AC±23)
2. RUN ENGINE AT APPROX. 1,500 RPM
3. CHECK COMPRESSOR FOR FOLLOWING:
(1) High pressure gauge reading is not lower and low
pressure gauge reading is not higher than normal.
(b) Metallic sound
(e) Leakage from shaft seal
If defects are found, repair the compressor.
4. CHECK MAGNETIC CLUTCH
(a) Inspect the pressure plate, and the rotor for signs of
oil.
(b) Check the clutch bearings for noise and grease leak-
age.
(e) Using an ohmmeter, measure the resistance of the
stator coil between the clutch lead wire and ground.
Standard resistance: 3.4 ± 3.8
at 20°C (68°F)
If resistance value is not as specified, replace the coil.
(d) Connect the positive (+) lead from the battery to ter-
minal 1, check that the magnetic clutch is energized.
If magnetic clutch is not energized, replace the coil.
NOTICE: Do not short positive (+) lead wire on the vehicle
by applying battery voltage.
Installation of Manifold Gauge Set
1. CLOSE BOTH HAND VALVES OF MANIFOLD GAUGE

2. INSTALL CHARGING HOSES OF GAUGE SET TO
CHARGING VALVES
Connect the low pressure hose to the low pressure charg-
ing valve and the high ..pressure hose to the high pres-
sure charging valve. Tighten the hose nuts by hand.
HINT Do not apply compressor oil to the seat of the con-
nection.

3. Hydraulic Control System
CONSTRUCTION
The hydraulic control is composed of an oil pump, rotated by the engine, which supplies hydraulic pres-
sure; a valve body which controls the hydraulic pressure and the opening and closing of the fluid pas-
saged; and a governor valve which supplies hydraulic pressure in accordance with vehicle speed.
OPERATION
Hydraulic pressure supplied by the oil pump is controlled± by the regulator valve; the resulting oil pres-
sure controlled by the regulator valve is called the line pressure.
Line pressure produces the hydraulic pressure for throttle pressure and governor pressure. Also, line
pressure produces hydraulic pressure for the operation of each brake and clutch in the planetary gear
unit.
The throttle valve acts to produce hydraulic pressure, called the throttle pressure, which responds to ac-
celerator pedal modulation. Throttle pressure increases as the accelerator pedal is depressed.
The governor valve produces hydraulic pressure, called the governor pressure, in response to vehicle
speed. Governor pressure increases as vehicle speed increases.
In accordance with the difference between throttle pressure and governor pressure, each shift valve
shifts, the fluid passages to the clutches are brakes in the planetary gear unit are opened and the
clutches and brakes operate, and shift change occurs.
The operation of the hydraulic control system, using the 2±3 shift valve as an example, is shown below;

HYDRAULIC TEST
PREPARATION
(a) Warm up the transaxle fluid.
(b) Remove the transaxle case test plug and connect the hydraulic pressure gauge.
SST 09992±00094 (Oil pressure gauge)
NOTICE:
wPerform the test at normal operating fluid temperature (122 ±176°F or 50 ± 80°C).
wThe line pressure test should always be carried out in pairs. One should observe the conditions
of wheels or wheel stoppers outside the vehicle while the other is performing the test.
MEASURE LINE PRESSURE
(a) Fully apply the parking brake and chock the four wheels.
(b) Start the engine and check idling rpm.
(e) Step down strongly on the brake pedal with your left foot and shift into D range.
(d) Measure the line pressure when the engine is idling.
(e) Press the accelerator pedal all the way down. Quickly read the highest line pressure when engine
speed reaches stall speed.
(f) In the same manner, perform the test in R range.
If the measured pressure are not up to specified values, recheck the throttle cable adjustment and
perform a retest.
