23. INSTALL SECOND COAST BRAKE BAND
(a) Place the band into the case.
(b) Install the pin through the oil pump mounting bolt
hole.
24. INSTALL FORWARD CLUTCH AND DIRECT CLUTCH
(a) Coat the race and bearing with petroleum jelly and
install it onto rear side of the forward clutch.
(b) Coat the race and bearing with petroleum jelly and
install it onto front side of the forward clutch.
HINT: There are two different-thick races (A540H) and
bearings (A540E) for adjustment of the input shaft thrust
play.
Bearing and race: A540H
mm (in.)
(c) Coat the thrust washer with petroleum jelly and
install it with the oil groove facing upward onto the
direct clutch drum.
(d) Mesh the hub of the forward clutch with flukes of
the direct clutch discs.
HINT: Be careful that the bearing and thrust washer do
not get out of place.

(e) Install the direct clutch and forward clutch into the
case.
HINT: Hold the direct clutch toward the forward clutch to
prevent the thrust washer from getting out of place.
(f) Check the distance between the direct clutch
drum and the sun gear input drum.
Distance: Approx. 3 mm (0.12 in.)
25. INSTALL OIL PUMP INTO CASE
(a) Coat a new O-ring with ATF and install it to the oil
pump.
(b) Place the oil pump through the input shaft, and
align the bolt holes of the pump body with the
transmission case.
NOTICE: Do not push on the oil pump strongly or the
oil seal ring will stick to the direct clutch drum.
(c) Install and tighten the seven bolts.
Torque: 225 kg-cm (16 ft-lb, 22 N-m)
26. MEASURE THRUST PLAY OF INPUT SHAFT
Measure the thrust play with a dial gauge.
Thrust play: 0.13 - 0.90 mm (0.0051 - 0.0354 in.)
HINT: There are two different-thick bearings (A540E) or
races (A540H) for the end of stator shaft. If the thrust
play is in excess of standard, select one of them.

2. HOW IS MAGNETIC CLUTCH ENERGIZED?
The general process until the magnetic clutch is energized is shown below.
Dual Pressure Switch º'ONº:
Refrigerant Condition (2.1 kg/cm2 (30 psi, 206 kPa) less than 27 kg/cm
2 (384 psi, 2,648 kPa))
Thermistor supplies temperature signal of evaporator to A/C amplifier.

Temperature Sensor ºONº:
Temperature of Temperature Sensor is less than 180
°C (356°F).
Magnetic Clutch ºONº
Revolution Detecting Sensor supplies RPM signal of compressor to A/C amplifier.
If compressor is not locked, magnetic clutch is continuously energized.
