| Detaching and re-attaching pulley from/onto compressor |
Note | t
| If the pulley overload safeguard has been released, check that the compressor is moving freely before replacing the pulley. Replace the entire compressor if stiff. |
| t
| The pulley overload protection function is described e.g. in → No.240. |
| t
| Depending on the engine version, detaching the pulley may involve detaching the compressor from the engine → Chapter. |
| t
| The compressor can be removed from the bracket and re-attached to it without opening the refrigerant pipes. |
| t
| Before removing it, mark the running direction of the poly-V-belt with chalk or a felt-tipped pen. If the belt runs in the opposite direction when it is refitted, this can cause breakage. |
| t
| Different compressors are installed depending on the engine, the vehicle type (A2, A3, A4 etc.), and the country version (attached to the right or left of engine, 6 cyl. petrol or diesel engine, hot or cold country). Check that the arrangement is correct → Parts List |
