AIR CONDITIONING COMPRESSOR AND MAGNETIC CLUTCH
1996 LAND CRUISER (RM451U)
REASSEMBLY
1. INSTALL COMPRESSOR
(a) Install the compressor with the 4 bolts. Torque: 25 N·m (250 kgf·cm, 18 ft·lbf)
(b) Connect the connector.
2. CONNECT DISCHARGE AND SUCTION HOSES Torque: 10 N·m (100 kgf·cm, 7 ft·lbf)
NOTICE:
Hoses should be connected immediately after the caps
have been removed.
HINT:
Lubricate 2 new O −rings with compressor oil and install the
hoses.
3. INSTALL AND INSPECT DRIVE BELT (See page AC−17 )
4. INSTALL ENGINE UNDER COVER
5. CONNECT NEGATIVE ( −) TERMINAL CABLE TO BAT-
TERY
6. EVACUATE AIR FROM REFRIGERATION SYSTEM
7. CHARGE SYSTEM WITH REFRIGERANT AND IN- SPECT FOR LEAKAGE OF REFRIGERANT
Specified amount:
850 ± 50 g (29.98 ± 1.76 oz.)
Using a gas leak detector, check for leakage of refrigerant.
If there is leakage, check the tightening torque at the joints.
8. INSPECT A/C OPERATION
Reassembly is in the reverse order of disassembly (See
page AC−35 ).
9. CHECK CLEARANCE OF MAGNETIC CLUTCH
(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:
0.5 ± 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 (0.020 in.)
