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

AB"DRIVE BELT REMOVAL
Due to the adoption of the Serpentine drive system with the
automatic tensioner, the following operation is required for
removing the drive belt:
1. Insert the 12.7sq. spinner handle into the tool hole of
the automatic tensioner and rotate it counterclockwise
until the automatic tensioner reaches to the stopper.
2. Align hole A with hole B for fixing by inserting the
L - shaped hexagon wrench, then remove the drive
belt.
Caution
When the drive belt is reused, use a chalk to indicate
an arrow of rotation direction on the back of the belt
so that it can be re - assembled in the same direction
as before.
AC"COMPRESSOR REMOVAL
Take care not to spill any compressor oil when removing
the compressor.
INSTALLATION SERVICE POINTS
"AACOMPRESSOR INSTALLATION
When installing a new compressor, first adjust the oil level
as follows.
1. Measure the oil in the compressor you removed.
(X cm
3)
2. Drain the amount of oil calculated by the following formula
from the new compressor. Now install the compressor.
130 cm
3–Xcm3=Ycm3
NOTE
(1) 130 cm3indicates the amount of oil sealed in the
new compressor at the factory.
(2) Y cm
3indicates the amount of oil in the refrigerant
line, compressor, and cooling unit.
INSPECTION
Compressor Magnetic Clutch Operation Check
Connect the compressor connector terminal to the battery
positive (+) terminal and ground the battery’s negative ( - )
terminal to the compressor unit. At that time, the magnetic
clutch should make a definite operating sound.

"BASNAP RING INSTALLATION
Using snap ring pliers, fit the snap ring so that the snap
ring’s tapered part is on the outside.
"CASELF-LOCKING NUT INSTALLATION
Using a special tool, as when removing the nut, secure the
armature and tighten the self-locking nut.
"DAAIR GAP ADJUSTMENT
Apply voltage from the battery to the magnetic clutch and
check that the clutch air gap is inside the type. value.
If outside the type. value, use a shim to adjust the gap.
Standard value: 0.3 – 0.5 mm
NOTE
The shims are available in 0.05 mm steps across the thickness
range 0.35 - 0.70 mm, and in 0.1 mm steps of thickness.
INSPECTION
Cooling temperature switch
1. Dip the metal part of the cooling temperature switch into
engine oil and increase the oil temperature using a gas
burner or similar.
Caution
Do not heat more than necessary.
2. When the oil temperature reaches the type. value, check
that voltage is supplied between the terminals.
