Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Magnetic clutch assembly
- Carrier disc
- Shim discs
- Spring ring
- Pulley
- Magnet coil.
The compressor is driven by the engine camshaft via the drive belt. As soon as the engine has started, the pulley (4) on the compressor drive shaft operates without hindrance.
Then the climate control system is switched on, the current passes through the magnetic coil (5), which is magnetized. This causes the carrier (1) on the compressor drive shaft to be pressed forward towards the pulley (4). The coupling is closed and the compressor rotates at the engine speed.
When the current to the magnetic coil is interrupted, the carrier disc (1) is released from the pulley (4) with the aid of return springs.
In order for the magnetic clutch to function correctly, the distance between the carrier disc (1) and the pulley (4) must be exactly correct. Shim discs (2) are therefore placed between them.
