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.

We've tried to keep all other shipping costs as low as we can.

Carriage starts at just £0.95 (inc VAT) for small items, with our most common courier rate set at £5.99 for orders of 5kg (enough for 5 litres of oil).

  • *Free shipping is available for UK Royal Mail, UPS Access Point™ (click & collect) and standard UK courier services (not express / priority / islands).
  • Courier surcharges mean we are unable to offer free "to the door" courier shipping from us in Cornwall up to Highlands / Grampian in Scotland - and because we send a lot of liquids, not every courier option is available to us.

  • Carriage charges are based on weight - please see our table of carriage costs for full details (although adding an item to your cart and viewing the calculated carriage is often easier!).
