FEBI101790 Febi Alternator Overrun Pulley

Basically, this little part lets your alternator spin freely in one direction, but grips and turns with the engine when it needs to. It’s a one – way clutch. Think of it like a little gatekeeper for the belt. It allows the belt to keep spinning the alternator even if the engine speed fluctuates a bit. It prevents the belt from being jerked around or putting extra stress on things. It’s part of the belt drive system, specifically for the alternator. The serpentine belt runs a bunch of accessories – your power steering pump, A/C compressor, and your alternator. The alternator needs to spin consistently to keep your battery charged and run all your electrical stuff. This clutch sits between the engine and the alternator pulley. It allows the alternator to spin a bit slower or faster than the engine’s crankshaft without causing issues with the belt or the alternator itself. If this clutch fails, you’ll likely notice a pretty loud rattling or chattering noise, especially at idle or low engine speeds. It’s almost like a metallic grinding. That’s because the alternator isn't spinning smoothly with the engine. That noise can get worse over time. More importantly, a failing clutch can put a lot of stress on your serpentine belt and even damage the alternator itself. It's a relatively inexpensive part to replace, and it can save you from a much bigger headache down the road. A lot of folks find them on Fixparts Online, makes it pretty easy to get. If you’re hearing any unusual noises from the front of the engine, it’s definitely something to check. Shop with confidence: Alternator Overrunning Clutch (MPN 101790) comes with a 3 year manufacturer guarantee!
