The HMMWV 8-groove over-running alternator/clutch pulley (often found on 200A systems) enables the serpentine belt to drive the alternator smoothly while preventing the alternator's high-inertia rotor from back-driving the belt during engine deceleration. This extends belt life and prevents system damage.[1, 2]
