ON-VEHICLE INSPECTION
INSPECT MAGNETIC CLUTCH
(a) Inspect the pressure plate and the rotor for signs of oil.
(b) Check the clutch bearings for noise and grease leakage.
(c) Connect the positive (+) lead from the battery to the termi-
nal on 4 and the negative (-) lead to the body ground.
(d) Check that the magnetic clutch is energized.
If the magnetic clutch is not energized, replace the magnetic
clutch.

NOTICE:
At the time of reassembly, the snap ring should be installed
so that its beveled side faces up.
(b) Using a plastic hammer, tap the rotor off the shaft.
NOTICE:
Be careful not to damage the pulley when tapping on the ro-
tor.
4. REMOVE STATOR
(a) Using a screwdriver disconnect the stator lead wires from
the compressor housing.
(b) Using SST, remove the snap ring.

REASSEMBLY
Reassembly is in the reverse order of disassembly (See
page AC-42).
INSPECT CLEARANCE OF MAGNETIC CLUTCH
(a) Set the dial-indicator to the pressure plate of the magnet-
ic clutch.
(b) Connect the magnetic clutch lead wire to the positive (+)
terminal of the battery.
(c) Check the clearance between the pressure plate and ro-
tor, when connect the negative (-) terminal of the battery.
Standard clearance:
0.5 ± 0.15 mm F(0.020 ± 0.0059 in.)
If the clearance is not within standard clearance adjust the
clearance using shims to obtain the standard clearance.

INSPECT PRESSURE SWITCH OPERATION
(a) Connect the positive (+) lead from the ohmmeter to termi-
nal 4 and the negative (-) lead to terminal 1.
(b) Check continuity between terminals when refrigerant
pressure is charged, as shown in the illustration.
If operation is not as specified, replace the pressure switch.
5. Condenser Fan Control:
INSPECT PRESSURE SWITCH OPERATION
(a) Connect the positive (+) lead from the ohmmeter to termi-
nal 2 and the negative (-) lead to terminal 3.
(b) Check continuity between terminals when refrigerant
pressure is changed, as shown in the illustration.
If operation is not as specified, replace the pressure switch.
6. STOP ENGINE AND SET OFF MANIFOLD GAUGE SET
7. CONNECT CONNECTOR TO PRESSURE SWITCH
