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.
