Belt Pulley Without A/C Clutch Overview

Belt Pulley without A/C Clutch Overview

• 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.

• 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).

1 Sealing Cap

2 Drive Plate

• Tightening specification 30 Nm

• 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, dampens rations and noise.

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

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

3 Circlip

• Replace

• Install on correct side (the flat side faces the A/C compressor).

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

4 Belt Pulley

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

• There are different versions (depending, for example, on the type of engine). Refer to the Parts Catalog.

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

5 A/C Compressor

• There are different versions depending on engine installed and the market. Refer to the Parts Catalog.

• Clean the A/C compressor flange before installing the pulley.

• Clean the compressor shaft thread and then coat the thread lightly with grease.
