COMPRESSOR CLUTCH CHECK

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

clutch set (see COMPRESSOR CLUTCH OVERHAUL ).

2. Check the rotor pulley bearing play and drag by rotating the rotor pulley (A) by hand. Replace the clutch

set with a new one if it is noisy or has excessive play/drag (see 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 COMPRESSOR CLUTCH
OVERHAUL ) and add or remove shims as needed to increase or decrease clearance.

Clearance: 0.5 +/- 0.15 mm (0.020 +/- 0.006 in.)

NOTE:

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

4. Release the field coil connector from the holder, then disconnect it. Check the thermal protector for

continuity. If there is no continuity, replace the thermal protector (see COMPRESSOR THERMAL
PROTECTOR REPLACEMENT ).

NOTE:

The thermal protector will have no continuity above 252° to 270°F (122° to
132°C). When the temperature drops below 241° to 219°F (116° to 104°C),
the thermal protector will have continuity.

5. Check resistance of the field coil. If resistance is not within specifications, replace the field coil (see

COMPRESSOR CLUTCH OVERHAUL ).

Field Coil Resistance: 3.05-3.35 ohms at 68°F (20°C)
