CHARGE HOSE
If the hoses are disconnected, cap the hoses with a blank
plug to prevent entry of dust, dirt, and water.
13. REMOVAL OF COMPRESSOR
Caution
Lay the towel on the brake tube to protect them. When
install the compressor, do not damage the brake tubes.This work must be done carefully so as not to spill the
compressor oil.
INSPECTIONN248CACl Checking for heat damage of the tension pulley.
lCheck for excessive play or deflection of the tension pulley.l Check for unusual wear of the tension pulley.
l Check for hardening of the compressor drive belt.

CONTINUITY CHECK OF THE COMPRESSOR’S MAGNETIC
CLUTCH
(1) Disconnect the compressor’s connector.
(2) Check to be sure that there is continuity between body
ground and terminal
@ at the compressor side.

CLUTCH(1) Disconnect the compressor’s connector.
(2) Connect terminal
@ at the compressor side to the positive(+) terminal of the battery, and ground the negative
(-)terminal of the battery to the compressor.
(3) The condition of the compressor’s magnetic clutch can be
considered satisfactory if the operation sound (a “click”
sound) of the magnetic clutch can be heard when this
check is made.
SERVICE POINTS OF INSTALLATIONN248DADa13. INSTALLATION OF COMPRESSOR
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 cc) of oil within the removed
compressor.(2) Wipe away (from the new compressor) the amount of
oil calculated according to the following formula, and
then install the new compressor.
New compressor oil amount 80 cc (4.9
cu.in.) - X cc =
Y cc
NOTE
Y cc indicates the amount of oil in the refrigerant line,
the condenser, the cooling unit, etc.
12. CONNECTION OF O-RING/
11. DISCHARGE HOSE/
10. SUCTION HOSE
(1) Take care that the O-rings are not caught, crushed or
cracked.(2) Since the O-ring size of suction hose is different from
that of discharge hose, be sure to connection correctly.

\1. REMOVAL OF CLUTCH HUB
(1) Fix the compressor with a vise. At this time, the rear
housing of the compressor must be in contact with the
vise.(2) If the clutch hub cannot be pulled off by hand, screw in
an 8 mm
(.315 in.) completely threaded bolt so as to
raise the clutch hub so it can be removed.
4. REMOVAL OF ROTOR
Using a plastic hammer, lightly tap the rotor off the shaft.

INSPECTIONN24TGAH
lCheck the surface of the clutch hub for scoring or bluing.
l Check the surface of the rotor for scoring or bluing.
l Check the sealing surfaces for cracks, scratches and
deformation.
lCheck the front housing for cracks or scoring on the sealing
surfaces.l Check the compressor shaft for scoring.
SERVICE POINTS OF REASSEMBLYN24StiAC11. INSTALLATION OF SHAFT SEAL
(1) Lubricate the shaft seal with specified compressor oil.
Specified compressor oil:
DENS0 OIL 6 or SUNISO 5GS(2) Set the shaft seal to the front housing so that the
projection side of the center ring is at the shaft seal
side.(3) Using a 21 mm
(.83 in,) socket, install the shaft seal.
7. INSTALLATION OF FRONT HOUSING
(1) Apply the specified compressor oil on the shaft.
Specified compressor oil:
DENS0 OIL 6 or SUNISO 5GS(2) Taking care to prevent injuring the lip area of the shaft
tool, mount the front housing.
(3) Mount the bolt on the shaft, and then measure the
shaft starting torque.
Standard value: 5.0 Nm (43
in.lbs.) or less
(4) Remove the bolt from the shaft.

(1) Remove the engine coolant temperature switch from the
water outlet fitting.
(2) Immerse the engine coolant temperature switch in oil and
heat by a gas stove or similar method so as to increase theoil temperature.
(3) Check to be sure that the engine coolant temperature
switch is switched OFF when the oil temperature reaches
the standard value.
Standard value:
112- 118°C (233-244°F)
CautionUse engine oil for this test; stir it well while heating,
and do not heat more than necessary.
