EVACUATING
1. CONNECT QUICK DISCONNECT ADAPTERS TO
CHARGING HOSES
2. REMOVE CAPS FROM SERVICE VALVES ON RE- FRIGERANT LINES
3. INSTALL MANIFOLD GAUGE SET
(a) Close both hand valves of manifold gauge set.
(b) Connect the quick disconnect adapters to the service valves.
4. EVACUATE AIR FROM REFRIGERATION SYSTEM
(a) Connect the vacuum pump adapter to the vacuum pump.
(b) Connect the center hose of the manifold gauge set to the vacuum pump adapter.
(c) Open both the high and low hand valves and run the vacu-
um pump.
(d) After 10 minutes or more, check that the low pressure
gauge indicates 750 mmHg (30 in.Hg) or more.
HINT:
If the reading is not 750 mmHg (30 in.Hg) or more, close both
hand valves of manifold gauge set and stop the vacuum pump.
Check the system for leaks and repair as necessary.
(e) Close both the high and low hand valves and stop the vac-
uum pump.
(f) Leave the system in this condition for 5 minutes or more and check that there is no gauge indicator.

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.)

INSPECTION
1. INSPECT ILLUMINATION OPERATION
Connect the positive (+) lead from the battery to terminal A −13
and the negative ( −) lead to terminal A−3, then check that the
illuminations light up.
If illuminations do not light up, test the bulb.
2. Air Inlet Control Switch:
INSPECT INDICATOR LIGHT OPERATION
(a) Connect the positive (+) lead from the battery to terminal
A−9 and the negative ( −) lead to terminal A−8.
(b) With the air inlet control button pushed in, check that the FRESH or RECIRC indicator light lights up.
(c) Next, push in the button again, and check that the indica-
tor light goes off and the other indicator light lights up.
