Generator Clutch
WARNING: This page is about a different car, the 2022 Ford Bronco Sport. However, it is still accessible from the selected car via links, so may be relevant.
The generator clutch is eventually serviced separately from the generator - check Refer to: Generator Pulley . The primary function is to separate the generator rotor inertia from the FEAD belt, lowering belt tension at high Revolutions Per Minute (RPM) and reducing NVH.
