A/C Compressor Clutch Check
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 Honda Odyssey, 2016 Honda Odyssey, 2015 Honda Odyssey, 2014 Honda Odyssey, and 2013 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.
- Check the pressure plate for discoloration, peeling, or other damage. If there is damage, replace the clutch set (see A/C COMPRESSOR CLUTCH OVERHAUL ).
- Check the pulley bearing play and drag by rotating the 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
).NOTE: The pulley and the pressure plate were mated at the factory by a burnishing operation. Always replace the pulley and the pressure plate as a set. Replacing only one part of the clutch set will cause clutch slippage.
- Measure the clearance between the pulley (A) and the pressure plate (B) all the way around. If the clearance is not within specified limits, remove the pressure plate (see A/C COMPRESSOR CLUTCH OVERHAUL
) and add or remove shims as needed to increase or decrease clearance.
Clearance: 0.35-0.60 mm (0.014-0.023 in)
NOTE: The shims are available in three thicknesses: 0.1 mm, 0.3 mm, and 0.5 mm. - Remove the pressure plate (see A/C COMPRESSOR CLUTCH OVERHAUL ), and inspect the pressure plate and pulley friction surface for wear. If there is excessive wear, roughness, or scoring, replace the clutch set.
- Inspect the friction surfaces and the A/C compressor shaft hub for excess oil. If excess oil is present, and it is not from the engine or power steering system, then the A/C compressor shaft seal is leaking. In that case, replace the A/C compressor (see A/C COMPRESSOR REPLACEMENT ).
- Measure the resistance of the field coil. If the resistance is not within specifications, replace the field coil (see A/C COMPRESSOR CLUTCH OVERHAUL
).
Field Coil Resistance: 3.9-4.3 Ω at 68°F (20°C)
