Febi 102328 Overrunning Alternator Pulley

The Febi 102328 is an overrunning alternator pulley (also known as an alternator freewheel clutch) designed to improve the performance and longevity of your vehicle's belt drive system. This critical component mounts directly onto the alternator drive shaft and transmits driving force in only one direction of rotation, effectively decoupling the alternator from crankshaft vibrations.

Key Features:

• OE-matching quality construction ensures reliable fitment and performance
• Reduces belt drive vibrations for smoother, quieter operation
• Extends serpentine belt service life by minimizing irregular stress
• Prevents alternator rotor from driving the pulley during engine shutdown
• Manufactured to strict OE specifications for optimal reliability
• Backed by Febi's 3-year manufacturer guarantee

When an alternator overrun pulley fails or becomes stuck, engine vibrations are no longer properly compensated, leading to unsteady belt operation at low engine speeds. This can cause premature failure of the belt tensioner and potentially result in serious engine damage. Febi overrunning alternator pulleys are intensively tested for dimensional accuracy, material quality, and tensile strength to ensure long-lasting, trouble-free performance. As one of the global leaders in automotive replacement parts with over 160 years of experience, Febi Bilstein delivers components you can trust for professional repairs.
