Compressor Clutch Check
1. Check the armature plate for discoloration, peeling, or other damage. If there is damage, replace the clutch set.
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.
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 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.
NOTE: The thermal protector will have no continuity above 252 to 262 °F (122 to 128 °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 coil.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
