INSTALLATION SERVICE POINT
>>A<< A/C 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 = 140mL <1300,
1600>, 120 mL <2000>
140 mL−X mL = Y mL <1300, 1600>
120 mL−X mL = Y mL <2000>
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 the each part from Y mL and discharge
from the new compressor.
Quantity:
•Evaporator: 60 mL
•Condenser: 15 mL
•Suction hose: 10 mL
•Receiver: 10 mL

COMPRESSOR MAGNETIC CLUTCH
OPERATION CHECK
Connect the compressor connector terminal to the
battery positive (+) terminal and earth the battery’s
negative (−) terminal to the compressor unit. At that
time, the magnetic clutch should make a definite
operating sound.

>>B<< SNAP RING INSTALLATION
Using snap ring pliers, fit the snap ring so that the
snap ring’s tapered part is on the outside.
>>C<< SELF-LOCKING NUT
INSTALLATION
Use the special tools to install the self-locking nut.
•Special spanner (MB991367)
•Pin (MB991386)
>>D<< AIR GAP ADJUSTMENT
Check that the clutch air gap is inside the standard
value. If outside the standard value, use a shim to
adjust the gap.
Standard value: 0.3 − 0.5 mm

REFRIGERANT TEMPERATURE SWITCH
CAUTION
Do not heat more than necessary.
1. Dip the metal part of the cooling temperature
switch into engine oil and increase the oil
temperature using a gas burner or similar.
2. When the oil temperature reaches the standard
value, check that voltage is supplied between the
terminals.
Standard value:
NOTE: When the oil temperature is 150
°C or
more and there is no continuity, the resistance will
not be 2
Ω or lower until the oil temperature
reduces to 120
°C or less.

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 hose and condenser assembly
nipples.
INSTALLATION SERVICE POINT
>>A<< CONDENSER INSTALLATION
When replacing the condenser, refill it with a
specified amount of compressor oil and install it. (to
the vehicle).

CONDENSER FAN MOTOR CHECK
Check to be sure that the condenser fan motor
operates when battery voltage is applied to terminal
2 and terminal 1 earthed.
