NOTE:

Typical clutchless compressor pulley drive hub shown in illustration.

The design of the Denso 6SEU16 and Valeo variable displacement A/C compressors does not require the use of an electromagnetic clutch, as the compressor is controlled by an integral control valve that allows refrigerant to bypass within the compressor. Refer to COMPRESSOR, A/C, DESCRIPTION .

The bridges (1) located on the compressor drive hub (2) are designed to break away in the event of compressor seizure. This action prevents damage to the serpentine accessory drive belt. Refer to COMPRESSOR, A/C, INSPECTION .

NOTE:

The compressor drive hub and the pulley and bearing assembly can not be serviced separately from the A/C compressor. In the event of drive hub or pulley and bearing assembly damage or failure, the A/C compressor, drive hub and pulley and bearing must be replaced as an assembly.

The compressor drive hub and the pulley and bearing assembly can not be serviced separately from the A/C compressors. The A/C compressors must be replaced if the drive hub or pulley and bearing assembly is worn or damaged.
