A3520321105 Mercedes-Benz Passenger ZAHNKRANZ

This thing has teeth cut all around the outer edge, and its main job is to work with the starter motor. When you turn the key, the starter sends a small gear out to grab onto those teeth on the ring gear. That’s what actually spins the engine over to get it started. It’s a pretty simple part, but absolutely critical. It’s bolted directly to the flywheel, which is attached to the engine’s crankshaft. So it spins with the engine, but it only gets actively used during starting. Once the engine is running, the ring gear isn't really doing anything until you shut it off and start it again. It’s kind of like a silent partner most of the time. Well, without a working ring gear, your car simply won’t start. If the teeth get damaged or worn down, the starter might spin and spin, but it won't be able to turn the engine over. You’ll notice if it’s going bad because you’ll hear a clicking sound when you try to start the car, or maybe just a whirring sound without the engine catching. It acts like a shield between the starter and the engine itself, transferring that initial power. It’s a relatively inexpensive part to replace compared to some other engine components, and if you’re doing a clutch job, it’s smart to check it and replace it if needed. You can find them easily enough – a place like Fixparts Online usually has a good selection. Ignoring a failing ring gear can lead to bigger problems down the road, so it’s best to address it as soon as you suspect something's off. Your trust matters: Ring Gear (MPN A3520321105) comes with a 12-month warranty!
