OVERVIEW - A/C COMPRESSOR BELT PULLEY, "Denso" VERSION "1"
WARNING: This page is about a different car, the 2024 Audi SQ7, 2024 Audi Q7, 2023 Audi SQ7, and 2023 Audi Q7. However, it is still accessible from the selected car via links, so may be relevant.
- 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.
- Different versions of the belt pulley (with different diameters) may be installed, depending on A/C compressor construction type and engine version. Refer to the Parts Information.
- As a replacement part, the belt pulley is delivered with the drive plate and the closure cap. 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 the Parts Information.
- Closure Cap
- Drive Plate
- Replace after removing
- Attached to the A/C compressor input shaft
- Clean the threads on the A/C compressor shaft before installing the drive plate.
- The threads on the new drive plate have already been greased with a specific amount of grease by the manufacturer.
- There are different versions. Refer to the Parts Information.
- The overload protection activates when the torque is too high (for example, if the A/C compressor runs with resistance) and the belt pulley runs freely without driving the A/C compressor.
- For installation, lightly coat rubber elements, for example with tire mounting paste or a soap solution (as a lubricant)
