REASSEMBLY
Reassembly is in the reverse order of disassembly (See
page AC±57).
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 positive (+)
terminal of the battery.
(c) Check the clearance between the pressure plate and ro-
tor when connecting the negative (±) terminal to the bat-
tery.
Standard clearance:
0.35 to 0.50 mm (0.014 to 0.024 in.)
If the clearance is not within the standard range, adjust the
clearance using shims to obtain the standard clearance.
Standard thickness:
0.1 mm (0.004 in.)
0.3 mm (0.012 in.)
0.5 mm (0.020in.)

INSTALLATION
1. INSTALL COMPRESSOR
(a) Install the compressor with the cooler bracket with the 3 bolts and nut.
Torque:
Bolt: 47 N´m (480 kgf´cm, 35 in.´lbf)
Nut: 25 N´m (255 kgf´cm, 18 in.´lbf)
(b) Connect the connector.
2. CONNECT DISCHARGE AND SUCTION HOSES
Connect both hoses with the 2 nuts.
Torque: 10 N´m (100 kgf´cm, 7 in.´lbf)
NOTICE:
Hoses should be connected immediately after the caps have been removed.
HINT:
Lubricate 2 new O±rings with compressor oil and install them to the hoses.
3. INSTALL AND CHECK DRIVE BELT (See page AC±17, AC±15)
4. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL
5. EVACUATE AIR FROM REFRIGERATION SYSTEM
6. CHARGE SYSTEM WITH REFRIGERANT
Specified amount:
Single A/C: 750 ± 50g (26.45 ± 1.76 oz.)
Dual A/C: 1050 ± 50g (37.03 ± 1.76 oz.)
7. INSPECT FOR LEAKAGE OF REFRIGERANT
Using a gas leak detector, check for leakage of refrigerant.
If there is leakage, check the tightening torque at the joints.
8. PERFORM INITIALIZATION (See page IN±20)
Some systems need initialization when disconnecting the cable from the negative battery terminal.

ON±VEHICLE INSPECTION
1. INSPECT CONDENSER FINS FOR BLOCKAGE OR DAMAGE
If the fins are clogged, wash them with water and dry with compressed air.
NOTICE:
Be careful not to damage the fins.
If the fins are bent, straighten them with a screwdriver or pliers.
2. INSPECT CONDENSER AND FITTINGS FOR LEAKAGE
Using a gas leak detector, check for leakage of refrigerant.
If there is leakage, check the tightening torque at the joints.
