Belt Pulley, Denso A/C Compressor, Version 2

Belt Pulley, Denso A/C Compressor, 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 belt pulley, it depends on engine version if it is necessary to remove A/C compressor from engine. Refer to => [ A/C Compressor, Removing From Bracket ] A/C Compressor, Removing From Bracket.

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

• As a replacement part, the pulley with the drive plate and cap come 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).

• Belt pulley, removing and installing, refer to => [ Denso A/C Compressor (Version 2) ] Denso A/C Compressor (Version 2).






1 Cap

2 Drive Plate

• Replace

• Bolted with the A/C compressor driveshaft, clean the compressor shaft thread before mounting the drive plate.

• The thread of the new drive plate has already been greased with a specific amount of a grease by the manufacturer.

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

• The overload protection takes over when 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.

• With rubber elements for decoupling belt pulley from A/C compressor input shaft, dampens vibrations and noise.

• For installation, lightly coat rubber elements, e.g. with tire mounting paste or a soap solution (as a lubricant)

• Removing and installing, refer to=> [ Denso A/C Compressor (Version 1) ] Denso A/C Compressor (Version 1).

• Tightening specification 30 Nm

3 Circlip

• Replace

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

• Removing and installing, refer to => [ Denso A/C Compressor (Version 1) ] Denso A/C Compressor (Version 1).

4 Belt Pulley

• Belt pulley is made of plastic and is sensitive to impact, therefore handle it with especial care.

• Different versions (depending, for example, on the type of engine). Refer to Electronic Parts Catalog (ETKA).

• Removing and installing, refer to => [ Denso A/C Compressor (Version 2) ] Denso A/C Compressor (Version 2).

5 A/C Compressor

• Different versions may be 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.

• Clean the compressor shaft thread before installing the drive plate and lightly coat it the lubricant.
