BELT PULLEY (WITHOUT A/C Clutch -N25-), REMOVING AND INSTALLING, A/C COMPRESSOR "Sanden" MANUFACTURER

WARNING: This page is about a different car, the 2021 Audi S4 and 2021 Audi A4 Quattro. However, it is still accessible from the selected car via links, so may be relevant.

The belt pulley is made of plastic and is sensitive to impact, therefore be especially careful when handling it.
If the belt pulley overload protection is triggered, then the A/C compressor must be checked for ease of movement before replacing the belt pulley. If the A/C compressor is difficult to move, this must be replaced completely.
If the drive plate overload protection was activated, the belt pulley can be rotated using the outer part of the drive plate so that the A/C compressor shaft and the hex fitting on the drive plate (inner part of the drive plate) do not rotate.
