Repairing Air Conditioner Magnetic Coupling N25
Repairing Air conditioner magnetic coupling - N25- |
Special tools, test and measuring equipment and aids required |
t | Two-arm extractor commercially available e. g. -Kukko 20-10- with hook 100 mm clamping depth |
t | Depth gauge |
t | Strap wrench |
Note
t | It is not necessary to open the refrigerant circuit to repair the magnetic coupling. |
t | Repairs on the magnetic coupling with the compressor installed should only occur in exceptional cases. |
t | If the compressor needs to be removed the vehicle must be serviced in a workshop with trained mechanics (service centre for air conditioning systems) because the refrigerant must first be drained at a service position. |

2 - | Clutch disc |
q | depending on the type it can have another shape, the damage is identical. |
q | remove → Fig. |
3 - | Spacers |
q | to set the gap between the clutch disk and belt pulley |
q | Clearance: 0.4…0.6 mm |
q | Check gap → Fig. |
4 - | Circlip |
q | replace: |
– | Fit on correct side: |
The smooth side points to the compressor. |
q | pay attention to correct fit in slot |
5 - | Belt pulley |
q | remove using a commercially available two or three armed extractor |
To avoid damaging the belt pulley pay attention to the correct position of the extractor. |
6 - | Circlip |
q | replace: |
– | Fit on correct side: |
The smooth side points to the compressor. |
q | pay attention to correct fit in slot |
7 - | Solenoid coil |
q | installing → Fig. |
Note
An overheating fuse is built into the solenoid coil. The overheating fuse will cut out the solenoid coil as soon as (e.g. because of compressor resistance) the magnetic coupling starts overheating. |
