@artem_pankovich: BMW N47 Timing Chain Stretch Test. • In this video, we work on a 2008 BMW 3 Series equipped with the 2.0 diesel N47D20 engine. • The N47 engine is well known for one of its most common issues - timing chain stretch. This vehicle arrived with typical symptoms, including timing chain noise and valvetrain-related knocking sounds from the upper part of the engine. • A major repair project is planned, but before disassembly begins, we first need to verify the condition of the timing chain system. • In this video, I demonstrate a professional method of measuring timing chain wear using a special measuring fixture that replaces the original chain tensioner. • The video covers: 🔧 timing chain stretch measurement 🔧 use of the special BMW measuring tool 🔧 comparison between a worn chain and a new chain • It is extremely important to perform this measurement only when the engine is locked in its proper timing position. • For accurate results: ✔ crankshaft must be locked ✔ camshaft must be locked ✔ engine must be positioned according to factory timing marks • Only then can the chain stretch be measured correctly and compared against specifications. • The video shows the complete procedure, including real measurement values from both a worn and a new timing chain. • A practical guide for BMW owners and technicians working with N47 diesel engines. • #supermechanik #artempankovich #carservice #goldenhandsmechanic #CarRepair
