VW A/C Compressor Clutch Drive - Febi 26958

Product Information

An Alternator Pulley is the wheel attached to the alternator shaft that connects to the engine’s serpentine belt or drive belt. As the engine runs, the belt turns the pulley, which spins the alternator’s rotor and generates electricity to charge the battery and power the vehicle’s electrical systems.

Many modern vehicles use an Overrunning Alternator Pulley or Overrunning Alternator Decoupler, which has a clutch-like mechanism that allows the alternator to "freewheel" when engine speed suddenly drops. This reduces belt vibration and improves efficiency.

• Squealing or chirping noises – especially at startup or when revving the engine.
• Battery warning light on dashboard – alternator isn’t charging properly due to poor pulley function.
• Intermittent charging issues – lights dimming or electronics flickering from unstable alternator output.
• Excessive belt vibration or wear – serpentine belt jumps, slips, or frays.
