Magnetic Clutch:
(See page AC±62)
Compressor:
1. INSTALL MANIFOLD GAUGE SET
(See page AC±11)
2. START ENGINE
3. INSPECT COMPRESSOR FOR METALLIC SOUND
Check that there is metallic sound from the compressor when
the A/C switch is turned ON.
If a metallic sound is heard, replace the compressor assem-
bly.
4. INSPECT PRESSURE OF REFRIGERATION SYSTEM
See ºRefrigeration System Inspection with Manifold Gauge
Setº on page AC±71.
5. STOP ENGINE
6. INSPECT VISUALLY FOR LEAKAGE OF REFRIGERANT
FROM SAFETY SEAL
If there is any leakage, replace the compressor assembly.

MAGNETIC CLUTCH DISASSEMBLY
1. REMOVE PRESSURE PLATE
(a) Using SST and socket wrench, remove the shaft bolt.
SST 07112±76060
Torque: 14 NVm (140 kgfVcm, 10ftVlbf)
(b) Install SST on the pressure plate.
SST 07112±66040

3. REMOVE STATOR
(a) Disconnect the stator lead wire from the compressor
housing.
(b) Using SST, remove the snap ring.
SST 07114±84020
ASSEMBLY NOTICE: The snap ring should be installed
so that its beveled side faces up.
(c) Remove the stator.
MAGNETIC CLUTCH ASSEMBLY
Assembly is in the reverse order of disassembly.
CHECK CLEARANCE OF MAGNETIC CLUTCH
(a) Set the dial±gauge to the pressure plate of the magnetic
clutch.
(b) Connect the magnetic clutch lead wire to the positive (+)
terminal of the battery.
± AIR CONDITIONING SYSTEMCOMPRESSORAC±89

(c) Check the clearance between the pressure plate and rotor,
then connect the negative (±) terminal of the battery.
Standard clearance:
0.5 + 0.15 mm (0.020 + 0.0059 in.)
If the clearance is not within specification, adjust the clear-
ance using shims to obtain the standard clearance.
Shim Thickness:
0.1 mm (0.004 in.)
0.3 mm (0.012 in.)
0.5 mm (0.020 in.)
COMPRESSOR INSTALLATION
1. INSTALL COMPRESSOR
(a) Install the stud bolt.
Torque: 26 NVm (265 kgfVcm, 19 ftVlbf)
(b) Install the compressor with 4 bolts and nut.
Torque: 52 NVm (530 kgfVcm, 38 ftVlbf)
(c) Connect the magnetic clutch connector.
(d) Install the engine under cover.
2. CONNECT DISCHARGE HOSE AND SUCTION HOSE TO
COMPRESSOR
NOTICE: Hoses should be connected immediately after
the caps have been removed.
Torque: 10 NVm (100 kgfVcm, 7 ftVlbf)
3. INSTALL POWER STEERING PUMP
Install the power steering pump with 2 bolts.
Torque: 58 NVm (590 kgfVcm, 43 ftVlbf)
4. INSTALL DRIVE BELT
5. INSTALL BATTERY
6. EVACUATE AIR IN REFRIGERATION SYSTEM AND
CHARGE WITREFRIGERANT
Specified amount:
700 + 50 g (24.96 + 1.76 oz.)
7. INSPECT FOR LEAKAGE OF REFRIGERANT
Using a gas leak tester, check for leakage of refrigerant.
If there is leakage, check the tightening torque at the joints.
