The A/C compressor clutch assembly consists of a stationary electromagnetic field coil (4), bearing and pulley assembly (3), shims (7) and a clutch plate (2) that is splined to the compressor shaft and secured by a bolt (1). These components provide the means to engage and disengage the A/C compressor from the engine accessory drive belt.

The A/C clutch bearing and pulley assembly on both A/C compressors are retained to the front of the compressor with a snap ring (6). The A/C clutch coil on the Denso A/C compressor is also retained to the front of the compressor using a snap ring (5). The A/C clutch coil on the Visteon A/C compressor is pressed onto the front of the compressor.
