Fig. 98: Removing A/C Compressor (With Specifications)

11. Install the compressor in the reverse order of removal, and note these items:

Inspect the A/C lines for any signs of contamination.

Replace the O-rings with new ones at each fitting, and apply a thin coat of
refrigerant oil before installing them. Be sure to use the correct O-rings for
HFC-134a (R-134a) to avoid leakage.

Use refrigerant oil (SP-10) for HFC-134a SANDEN spiral type A/C
compressor only.

To avoid contamination, do not return the oil to the container once
dispensed, and never mix it with other refrigerant oils.

Immediately after using the oil, reinstall the cap on the container, and seal
it to avoid moisture absorption.

Do not spill the refrigerant oil on the vehicle; it may damage the paint; if
the refrigerant oil contacts the paint, wash it off immediately.

Charge the system (see SYSTEM CHARGING ).

1. Check the armature plate for discoloration, peeling, or other damage. If there is

damage, replace the clutch set (see A/C COMPRESSOR CLUTCH
OVERHAUL ).

2. Check the rotor pulley bearing play and drag by rotating the rotor pulley by

hand. Replace the clutch set with a new one if it is noisy or has excessive
play/drag (see A/C COMPRESSOR CLUTCH OVERHAUL ).

3. Measure the clearance between the rotor pulley (A) and the armature plate (B)

all the way around. If the clearance is not within specified limits, remove the
armature plate (see A/C COMPRESSOR CLUTCH OVERHAUL ) and add
or remove shims as needed to increase or decrease clearance.

Clearance: 0.35-0.65 mm (0.014-0.026 in.)

NOTE:

The shims are available in four thicknesses: 0.1 mm, 0.2
mm, 0.4 mm, and 0.5 mm.

4. Check for continuity between the A/C compressor clutch connector No. 1 and

No. 3. If there is no continuity, replace the thermal protector (see A/C
COMPRESSOR THERMAL PROTECTOR REPLACEMENT ).

Connector No. 1 And No. 3

5. Disconnect the field coil connector (A). Check resistance of the field coil. If

resistance is not within specifications, replace the field coil (see A/C

NOTE:

The thermal protector will have no continuity above
about 252 to 262°F (122 to 128°C). When the
temperature drops below about 241 to 219°F (116 to
104°C), the thermal protector will have continuity.
