Overrunning Alternator Pulley with Internal Clutch Mechanism SKU: QT58684

This is an overrunning alternator pulley with built-in clutch functionality, designed to reduce belt stress and prevent reverse drive under deceleration.

It lets the alternator freewheel when the engine slows, helping to damp vibrations and extend belt and alternator life in farm equipment.

• Includes internal overrunning clutch for smooth disengagement
• Designed for heavy-duty alternator use in farming environments
• Constructed for durability under vibration and load cycles
• Improves belt life by reducing reverse torque on startup/shutdown

Installation Tip: Use a proper pulley installation tool to avoid damaging the clutch, align the pulley carefully on the shaft, and torque mounting hardware to spec.

This pulley with overrunning clutch is a dependable option for maintaining reliable belt-driven charging systems in agricultural machinery.
