REMOVAL SERVICE POINTS
.
<<A>> DRIVE BELT REMOVAL
CAUTION
When reusing the drive belt, mark an arrow which indi-
cates the turning direction (right turn) on the back of the
drive belt with a chalk, etc.
Insert the socket-wrench handle into the tool hole for auto-ten-
sioner and turn it to the arrow direction. Reduce the drive belt
tension and remove the drive belt.
.
<<B>> DISCHARGE HOSE/SUCTION HOSE REMOVAL
CAUTION
Seal the hoses completely, otherwise the compressor oil
and receiver will absorb water vapor easily, possibly dam-
aging the compressor and deteriorating performance.
Plug the disconnected hose and compressor nipple to prevent
foreign matter from getting into them.
.
<<C>> COMPRESSOR REMOVAL
When removing the compressor, be careful not to spill the com-
pressor oil.
INSTALLATION SERVICE POINT
.
>>A<< COMPRESSOR INSTALLATION
If a new compressor is installed, first adjust the amount of oil
according to the procedures described below, and then install
the compressor.
1. Measure the amount [X cm
3
(X floz)] of oil within the
removed compressor.
2. Drain (from the new compressor) the amount [Y cm
3
(Y
floz)] of oil calculated according to the following formula, and
then install the new compressor.
<Vehicles without rear A/C>
New compressor oil amount = 120cm
3
(4.2 floz)
<Vehicles with rear A/C>
New compressor oil amount = 140cm

(4.9 floz
− X floz = Y floz)
NOTE: Y cm
3
(Y floz) indicates the amount of oil in the refriger-
ant line, the condenser, the evaporator, etc.
NOTE: When replacing the following parts at the same times as
the compressor, subtract the rated oil amount of the each part
from Y cm
3
(Y floz) and discharge from the new compressor.
Quantity:
• Evaporator: 60 cm

(2.0 floz)
• Condenser: 15 cm

AIR CONDITIONING COMPRESSOR CLUTCH
OPERATION INSPECTION
Connect the positive battery terminal to the air conditioning
compressor clutch connector terminal 3, and ground the nega-
tive battery terminal to the body of the compressor. The condi-
tion is normal if the sound of the magnetic clutch (click) can be
heard.

DISASSEMBLY SERVICE POINT
.
<<A>> ARMATURE PLATE REMOVAL
1. Remove the armature plate mounting nut.
2. Tighten the M10 bolt into the armature plate bolt hole and
disconnect the serration of the shaft and the armature plate.
ASSEMBLY SERVICE POINTS
.
>>A<< CLUTCH COIL INSTALLATION
Install the clutch coil to the compressor, mating the compressor
body slot to the clutch coil projection.
.
>>B<< SNAP RING INSTALLATION
Install the snap ring taking care not to enlarge the inner diame-
ter too much. When the inner diameter is over 30.5 mm (1.2
inch) resulting from being enlarged too much, replace the snap
ring with a new one.
.
>>C<< AIR GAP ADJUSTMENT
Check whether or not the air gap of the clutch is within the stan-
dard value.
Standard value: 0.35
− 0.65 mm (0.014 − 0.026 inch)
NOTE: If there is a deviation of the air gap from the standard
value, make the necessary adjustment by adjusting the number
of shims.
