Description
FEBI – Alternator Freewheel Clutch
The FEBI Alternator Overrun Pulley is a precision-engineered automotive component designed to decouple the alternator from the engine during deceleration, reducing belt tension and improving overall engine efficiency.
Features:
- Enhances Belt System Efficiency: Reduces belt tension and prevents jerky alternator movement during deceleration.
- One-Way Clutch Mechanism: Integrated overrun clutch allows alternator to freewheel, improving performance and reducing strain.
- Reduces Vibration and Noise: Helps minimise belt whip, whirring noises, and component wear for quieter operation.
- Improves Fuel Economy: A properly functioning overrun pulley reduces mechanical drag and contributes to better fuel efficiency.
- Suitable for Various Engines: Compatible with a wide range of petrol and diesel vehicles, including models with start-stop systems.
- Long-Lasting Durability: Built with corrosion-resistant materials and tested for high rotational and thermal stress.
- Prevents Electrical Issues: Ensures stable alternator operation, preventing voltage fluctuations and protecting the battery.
As a component subjected to high rotational forces, the FEBI alternator decoupler pulley is built with premium materials to withstand high RPMs and thermal variations.
