BMW Timing Chain Idler Sprocket Mounting Screw - Genuine BMW 13527617486

Product Information

An engine timing sprocket is a toothed wheel mounted on the crankshaft or camshaft that engages with a timing chain or belt to synchronize the rotation of the engine’s valves and pistons. This precise timing ensures efficient combustion, smooth power delivery, and prevents internal engine damage. A properly functioning sprocket is essential for maintaining correct valve timing and overall engine performance.

• Rattling or knocking noises from the timing area, often due to worn sprocket teeth.
• Engine misfires or poor performance, caused by incorrect valve timing.
• Complete engine failure to start, if the sprocket slips or fails to engage properly.

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
