In this video, young mechanic Aiman will show you how to remove, diagnose, replace or install stator coil, clutch & bearing on AC compressor in your car.
Even though these steps are done when the air conditioning compressor has been taken out, the same process should apply when the compressor is installed or mounted in the engine bay.
The AC compressor shown in the video is from a 2004 Honda Accord 2.4L (which is the same as 2004, 2005, 2006 & 2007 model years DX, LX & EX) but should also be the same for other Honda models such as Civic, CRV, Element, Pilot, Odyssey etc..
Compressor Clutch
An electromagnetic clutch provides the mechanical link between the pulley and the compressor input shaft whenever air conditioning is demanded. The compressor drive hub is usually found at the front of the pulley and is attached directly to the compressor driveshaft. A stationary electromagnetic coil is attached to the face of the compressor, behind the pulley. When current flows through the coil windings, a magnetic field pulls the drive hub snug against the pulley. Now functioning as a unit, they drive the compressor as long as the coil is energized.
Compressor Clutch Inspection
Inspect the front of the compressor for oil, which could indicate a leaking front compressor seal. This would not only cause a refrigerant leak, but the oil could cause the compressor clutch to slip. Connect manifold gauges and make sure there is adequate refrigerant in the system. Start the engine and turn on the A/C. If the compressor clutch does not engage, turn off the engine. Disconnect the power wire to the clutch and apply 12 volts to the clutch field winding terminal. If the clutch engages, then check the power supply to the clutch, including the system protection devices and electronic compressor controls. If the clutch does not engage, then check the clutch ground connection and coil resistance. If resistance is not within specification, then replace the coil or clutch assembly. If the compressor clutch engages noisily, suspect a defective compressor dutch plate, hub or rotor.
Compressor Clutch Replacement
Although most compressor clutch and drive pulley components can be serviced in the engine compartment, it is advisable to recover the refrigerant and remove the compressor from the vehicle. After the compressor is removed, clamp it in a suitable holding device with the clutch facing upward. If the clutch plate and hub are fastened to the shaft using a retainer such as a C-clip, remove the clip using the appropriate removal tool. If the clutch plate and hub are fastened to the shaft using a bolt or nut, hold the clutch plate using an appropriate clutch hub holding tool and remove the bolt or nut.
After the retainer has been removed, attach a clutch plate and hub puller into the hub assembly. Turn the center screw of the puller in on the puller body until the clutch plate and hub have been separated from the shaft. Remove the Woodruff key from the hub and place it aside for future use. To remove the clutch rotor assembly, remove the rotor and bearing retaining ring and install the appropriate puller. Hold the puller in place and tighten the puller screw against the guide to remove the pulley rotor and bearing assembly. After the rotor has been removed, inspect it to see if the bearing can be replaced. On some compressors, the bearing and rotor must be replaced as an assembly. However, if the bearing is replaceable, drive the bearing out of the rotor hub with a rotor bearing removal tool.
