REASSEMBLY
Reassembly is in the reverse of disassembly
(See page AC-63).
AFTER REASSEMBLY, CHECK MAGNETIC CLUTCH
CLEARANCE
(a) Set the dial indicator to the pressure plate of the magnetic
clutch.
(b) Connect the magnetic clutch lead wire to the battery posi-
tive (+) terminal.
(c) Check the clearance between the pressure plate and ro-
tor when connecting the negative (-) terminal to the bat-
tery.
Standard clearance:
0.5 ± 0.15 mm (0.020 ± 0.0059 in.)
If the clearance is not within the standard clearance, adjust the
clearance using shims to obtain the standard clearance.
Shim thickness:
0.1 mm (0.004 in.)
0.3 mm (0.012 in.)
0.5 mm (0.020in.)

MAGNETIC CLUTCH RELAY
INSPECTION
HINT:
The magnetic clutch relay is built in the engine room junction
block. Since the relay is constructed with a relay block that is in
the junction block as a unit, it is impossible to disconnect the
wire harness connecting with the relay block.
If the relay has a malfunction, replace it with the junction block
assembly wire harness together.

1. SET VEHICLE IN THESE CONDITION
(a) Engine speed at 1,500 rpm
(b) Blower speed control switch at ºHIº position
(c) Temperature control dial at ºMAX. COOLº position
(d) Manifold gauge set setting
2. INSPECT PRESSURE SWITCH OPERATION
(a) Disconnect the connector.
(b) Inspect pressure switch continuity (Magnetic Clutch Con-
trol)
(1) Connect the positive (+) lead from the ohmmeter to
terminal 1 and the negative (-) lead to terminal 2.
(2) Check continuity between terminals when the re-
frigerant pressure is changed, as shown in the il-
lustration.
If continuity is not as specified, replace the pressure switch.

INSTALLATION
1. CHECK TORQUE CONVERTER CLUTCH INSTALLA-
TION
Using calipers and a straight edge, measure the distance from
the installed surface of the transmission housing to the installed
surface of the torque converter clutch.
Correct distance: More than 17.1 mm (0.673 in.)
2. TRANSMISSION INSTALLATION
Installation is in the reverse order of removal
(See page AT-33).
HINT:

Transmission control rod and the park/neutral position
switch (See page DI-361)

ATF level (See page AT-3-1)

Conduct the road test of the vehicle (See page DI-361)
