55A-71

CAUTION

To reuse the drive belt, draw an arrow indicating 
the rotating direction (clockwise) on the back of 
the belt using chalk, etc.

3. Insert an L-shaped hexagon wrench, etc. into the 

hole to fix and then remove the drive belt.

<<C>> COMPRESSOR REMOVAL
Take care not to spill any compressor oil when 
removing the compressor.

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 = 120 
mL<MSC90CA> or 140 mL<MSC120CA>

120 mL

X mL = Y mL<MSC90CA> or 140 

mL

X mL = Y mL<MSC120CA>

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.

>>D<< AIR GAP ADJUSTMENT

Apply voltage from the battery to the magnetic clutch 
and check that the clutch air gap is inside the 
standard value. If outside the standard value, use a 
shim to adjust the gap.

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 ohms or lower until the oil temperature 
reduces to 120
