REMOVAL SERVICE POINTS

.

<<A>> FLEXIBLE SUCTION HOSE AND FLEXIBLE
DISCHARGE HOSE DISCONNECTION

CAUTION

As the compressor oil and receiver are highly moisture
absorbent, use a non-porous material to plug the hose and
nipples.
To prevent the entry of dust or other foreign bodies, plug the
dismantled hoses and compressor nipples.

.

<<B>> COMPRESSOR REMOVAL

Take care not to spill any compressor oil when removing the
compressor.

INSTALLATION SERVICE POINT

.

>>A<< FLEXIBLE SUCTION HOSE CONNECTION

To prevent mis-alignment of suction hose to bracket use the
folowing assembly procedure.
1. Insert hoseconnector into compressor and hand start bolt.

2. Assemble P-clip to hose and suction hose bracket. Tighten

bolt.

3. Tighten bolt between compressor and hose connector.

.

>>B<< 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 ml) 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 = 140 ml

140 ml

− X ml = Y ml

NOTE: Y ml indicates the amount of oil in the refrigerant 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 each part from
Y ml and discharge from the new compressor.

Compressor oil: ND Oil 8

Quantity:

Evaporator: 40 ml
Condenser: 40 ml
Receiver: 40 ml

COMPRESSOR AIR CONDITIONING
COMPRESSOR CLUTCH OPERATION CHECK

Connect the compressor connector terminal to the battery posi-
tive (+) terminal and ground the battery’s negative (-) terminal
to the compressor unit. At that time, the air conditioning com-
pressor clutch should make a definite operating sound.

.

AIR GAP ADJUSTMENT

Check whether or not the air gap of the clutch is within the stan-
dard value.

Standard value:

0.35

− 0.60mm

NOTE: If there is a deviation of the air gap from the standard
value, assess the operation of the clutch and replace the com-
pressor assembly as required.
