INA 535029810 BDC FEAD Overrunning Alternator Pulley

Description

The INA BDC FEAD Overrunning Alternator Pulley efficiently decouples the alternator from engine vibrations. This pulley is crucial for belt drive systems in various engine applications. Its design minimizes belt noise and extends belt life by reducing stress on the belt and other components. This pulley is manufactured in China and carries MPN 535029810 with dimensions of 62 x 92 x 113 mm.

Key Features & Benefits

This pulley basically lets the alternator spin freely in one direction, but transmits power in the other. Think of it like a one – way clutch. It allows the engine’s belt to drive the alternator to charge your battery and run electrical systems, but it disengages when the alternator starts to spin faster than the belt – like when you rev the engine quickly or shut it off. It smooths things out. It’s part of your front end accessory drive – that’s the system that runs your alternator, power steering pump, and sometimes the AC compressor, all powered by a single belt. This specific pulley is for the alternator. It’s positioned between the belt and the alternator shaft.

Symptoms, Risks & Replacements

This pulley prevents a few things from happening. Without it, when you quickly change engine speed, the alternator could actually try to drive the engine belt instead of being driven by it. That causes a lot of strain on the belt, the alternator bearings, and even the engine itself. It also creates a really irritating squealing or rattling noise. It acts like a shield, protecting those components from shock and wear. You’ll notice if this pulley fails – you'll probably hear a pretty loud noise, especially when starting or shutting off the engine, or if the belt starts slipping and you get a charging light. We carry a good selection of these at Fixparts Online, and replacing it when it goes bad is a lot cheaper than replacing the alternator or a damaged belt.
