Compressor Assembly
INSPECTION
1) Install manifold gauge set (1) as shown in the figure.
2) Close Hi (4) and Lo (5) side valves.
3) Run engine at fast idle.
4) Check compressor for the following items.
If any of the above checks indicated a defect, repair com-
pressor.
High pressure gauge reading is not low and low pressure
gauge reading is not higher than normal.
Metallic sound.
Leakage from compressor. CAUTION:
None of refrigerant, compressor oil and component parts is interchangeable between two types of
A/C: one using CFC-12 (R-12) and the other using HFC-134a (R-134a).
For identification between these two types, refer to page 66.
When replenishing or changing refrigerant and compressor oil and when replacing parts, make sure
that the material or the part to be used is appropriate to the A/C installed in the vehicle being serviced.
Use of incorrect refrigerant or compressor oil will result in leakage of refrigerant, damage in parts or
other faulty condition.
When servicing the compressor, keep dirt or foreign material away from getting on or into the com-
pressor parts and system. Clean tools and a clean work area are important for proper service.
The compressor connection and the outside of the compressor should be cleaned before any “On-
vehicle” repair or before removal of the compressor. The parts must be kept clean at all times and any
parts to be reassembled should be cleaned with Trichloromethane, naphtha, kerosene or equivalent
solvent and dried with dry air. Use only lint free cloths to wipe parts.
The operations described are based on bench overhaul with compressor removed from the vehicle,
except as noted. They have been prepared in order of accessibility of the components.
When compressor is removed from the vehicle for servicing, the oil remaining in the compressor
should be discarded and new refrigerant oil added to the compressor.
Minor repair procedures may be done on the vehicle without discharging the system. Major repair pro-
cedures require that the system be discharged of refrigerant.

AIR CONDITIONING (OPTIONAL) 1B-39
REMOVAL
1) Run engine at idle with A/C ON for 10 minutes.
2) Disconnect negative (–) cable at battery.
3) Recover refrigerant from refrigeration system using recovery
and recycling equipment.
4) Remove P/S pump referring to step 4) to 7) of “REMOVAL”
under “P/S PUMP” in Section 3B1.
5) Disconnect magnet clutch connector.
6) Disconnect suction hose (1) and discharge hose (2) from
compressor.
7) Remove compressor (1) from its mount (2).NOTE:
The amount of compressor oil at removed must be mea-
sured and the same amount must be poured when install-
ing the compressor.
NOTE:
It is not necessary to drain P/S fluid.
NOTE:
Cap open fitting immediately to keep moisture out of sys-
tem.

the same amount as that drained from compressor.
Refer to “REPLENISHING COMPRESSOR OIL” in this sec-
tion.
Install P/S pump referring to “P/S PUMP” in Section 3B1.
Evacuate and charge system. Refer to “EVACUATING” and
“CHARGING” in this section. CAUTION:
Be sure to use HFC-134a (R-134a) compressor oil.

Magnet Clutch
INSPECTION
Check the following items.
Check no sigh of compressor oil leakage
Check magnet clutch pulley bearing for noise and grease
leakage.
Check magnet clutch operation as follows :
a) Connect battery (1) and ammeter (2) to compressor (3) as
shown.
b) Check that steadily locks between armature plate (4) and
magnet clutch pulley (5).
c) Check that ammeter (2) indicates specified current.
Specified current of magnet clutch :
4A MAX at 12V
If any detects are found, repair or replace magnet clutch assem-
bly.
