BCASE COVER, EVAPORATOR REMOVAL
The evaporator, which has been installed in a factory, has
no case cover. Follow the steps below to remove that
evaporator.
1. Cut the case along the shown line to remove the cooling
and blower unit.
2. Remove the air thermo sensor from the evaporator, and
then remove the evaporator towards you, being careful
not to damage its core.
INSPECTION
BLOWER MOTOR CHECK
When battery voltage is applied between the terminals, check
that the motor operates. Also, check that there is no abnormal
noise.
RESISTOR CHECK
Use a circuit tester to measure the resistance between the
terminals as indicated below. Check that the measured value
is at the standard value.
Standard value:
Measurement terminalStandard value Ω
Between terminals 3 and 22.81 ± 10%
Between terminals 3 and 41.28 ± 10%
Between terminals 3 and 10.33 ± 10%

AIR THERMO-SENSOR CHECK
Measure the resistance between the sensor terminals in two
or more different temperature conditions. The resistance
values must conform to the values shown in the graph.
NOTE
The temperatures at checking must be within the range shown
in the characteristic curve.kΩ

ADRIVE BELT REMOVAL
1. Align the hole in the auto-tensioner bracket with that in
the arm and insert a screwdriver into the holes.
2. Remove the drive belt.
BSUCTION HOSE, DISCHARGE HOSE
DISCONNECTION
Plug the disconnected hose and the compressor nipple not
to let foreign matter get into them.
Caution
Seal the hoses completely, otherwise the compressor
oil and receiver will absorb water vapour easily.
CCOMPRESSOR REMOVAL
When doing this work, be careful not to spill the compressor
oil.

INSTALLATION SERVICE POINT
ACOMPRESSOR 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 m
) of oil within the removed
compressor.
2. Drain (from the new compressor) the amount of oil
calculated according to the following formula, and then
install the new compressor.
New compressor oil amount
120 to 140 m
– X m
= Y m

NOTE
(1)“120 to 140 ml” is the amount of oil filled in a new
compressor.
(2) Y m
indicates the amount of oil in the refrigerant
line, the condenser, the cooling unit etc.
INSPECTION
REFRIGERANT-TEMPERATURE SWITCH SIMPLE
CHECK
When the A/C is off, check that there is continuity between
the refrigerant-temperature switch terminals. If no, replace
the compressor assembly.
COMPRESSOR MAGNETIC CLUTCH OPERATION
INSPECTION
Connect the battery (+) terminal to the compressor side
terminal, and earth the battery (–) terminal to the body of
the compressor. The condition is normal if the sound of the
magnetic clutch (click) can be heard.AView A

BSNAP RING INSTALLATION
Install the snap ring using a pair of snap ring pliers so that
the tapered surface is at the outer side.
CARMATURE INSTALLATION
Align the serration projection of the crankshaft with the notch
in the armature, and then fit them together.
DSELF-LOCKING NUT INSTALLATION
Use the special tool to hold the magnet clutch, and tighten
the self-locking nut in the same manner as removal.
EAIR GAP ADJUSTMENT
Check whether or not the air gap of the clutch is within the
standard value. If there is a deviation of the air gap from
the standard value, make the necessary adjustment by
adjusting the number of shims.
