An alternator overrun pulley, mounted directly on the drive shaft of the generator, transmits the driving force only in one direction of rotation. This decouples the generator from the vibrations of the crankshaft, allowing the belt drive to run smoother and quieter and extending the service life of the drive belt.
If the alternator overrun pulley is stuck, engine vibrations are no longer compensated and lead to unsteady belt running at low engine speeds. Due to the increased movements of the belt, high forces act on the tensioning element which can cause both this and the fixed alternator overrun pulley to fail prematurely. In the worst case scenario, this can result in serious engine damage.
Alternator overrun pulleys from Febi are therefore intensively tested. Their quality management tests the offered components for various requirements and loads, e.g. accuracy of fit, dimensional accuracy, material quality, and tensile strength.
