Belt Pulley, Removing And Installing, DENSO A/C Compressor: Notes
Special tools and workshop equipment required
- Commercially available oil filter band wrench
The belt pulley is sensitive to impact. Handle it with special care.
If the belt pulley overload protection was activated, check the A/C compressor for ease of movement before replacing the belt pulley. Replace an A/C compressor that is not operating smoothly.
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.
The following shows the A/C compressor on a vehicle with a 4-cylinder engine. On vehicles with a 5-cylinder engine (Audi TT RS) the layout of the components is different however the removing and installing of the A/C compressor belt pulley is performed in the same way.
