TYC Replacement Alternator Clutch Pulley

The TYC Replacement Alternator Clutch Pulley is an overrunning alternator decoupler (OAD) pulley. It is built to replace a worn or failed clutch pulley on your alternator. Also called an alternator decoupler pulley, overrunning alternator pulley or one-way clutch pulley, it helps the serpentine belt drive system run smoothly and quietly.

Key Features:

• Built-in one-way clutch lets the alternator spin freely when engine speed drops, which reduces belt vibration and wear
• Helps absorb torsional vibration from the engine, which protects the belt, tensioner and alternator bearings
• Helps prevent belt chirp, flutter and noise caused by a failing clutch
• Designed as a replacement for the original equipment pulley
• Available in several groove and amperage configurations for different alternator applications

A worn clutch pulley can cause squealing, belt slap, rough idle behavior and early belt or tensioner failure. Replacing it restores smooth alternator operation. TYC is an established maker of aftermarket replacement parts, and this line is meant to give a dependable, direct-replacement alternative.
