A/C Compressor Belt Pulley - Version 2

A/C Compressor Belt Pulley - Version 2

• If overload protection of pulley triggers, check the A/C compressor for ease of motion before replacing the pulley. If the A/C compressor creates friction, replace it completely.

• To remove the belt pulley, it is not always necessary to detach the A/C compressor from the engine. Refer to 6 cylinder diesel => [ A/C Compressor From Bracket ] A/C Compressor from Bracket, 6 cylinder gas => [ Compressor ] Compressor and W12 => [ A/C Compressor from Bracket ] A/C Compressor from Bracket. Depending on the engine type, it may be necessary to loosen the lock carrier from the vehicle and to pull it slightly forward (to make space).

• Different versions of the belt pulley (with different diameters) may be installed, depending on A/C compressor construction type and engine version. Refer to Electronic Parts Catalog (ETKA).

• As a replacement part, the belt pulley with the drive plate and the cap is available under one part number. The belt pulley and the drive plate are held together with one bolt (when the bolt is no longer needed, dispose of it). When the bolt was manufactured, a predetermined amount of a specific grease was applied to the threads in the drive plate; this amount is sufficient for bolting the drive plate to the compressor one time (a drive plate, which has been removed, cannot be reused). Refer to Electronic Parts Catalog (ETKA).

• Remove and reinstall the belt pulley, refer to => [ Belt Pulley From A/C Compressor Version 2 ] Belt Pulley From A/C Compressor Version 2.






1 Screw

• Tightening specification 20 Nm

• Replace

• Loosening and tightening, refer to => [ Belt Pulley From A/C Compressor Version 2 ] Belt Pulley From A/C Compressor Version 2.

2 Drive Plate

• Different versions. Refer to Electronic Parts Catalog (ETKA).

• Removing and installing, refer to => [ Belt Pulley From A/C Compressor Version 2 ] Belt Pulley From A/C Compressor Version 2.

• Disengages when the torque is too high (for example, A/C compressor not operating smoothly).

3 Circlip

• Replace

• install on correct side (flat side toward A/C compressor)

• Removing and Installing, refer to => [ Belt Pulley From A/C Compressor Version 2 ] Belt Pulley From A/C Compressor Version 2.

4 Belt Pulley

• the overload protection takes over when the rubber element on the belt pulley loosens because the torque is excessive (for example, if the A/C compressor runs with resistance) and the belt pulley runs freely without driving the A/C compressor.

• Different versions. Refer to Electronic Parts Catalog (ETKA).

• Removing and installing, refer to => [ Belt Pulley From A/C Compressor Version 2 ] Belt Pulley From A/C Compressor Version 2.

• Under certain conditions (for example, rough engine idle), rubber element of pulley can disengage without a malfunction existing at compressor or in refrigerant circuit.

5 A/C Compressor

• Different versions are installed, depending on engine version and country version of vehicle. Refer to Electronic Parts Catalog (ETKA).

• Clean A/C compressor flange before sliding on pulley.
