Mercedes Engine Timing Crankshaft Gear - Genuine Mercedes 2780520503

Product Information

An engine timing crankshaft gear is a precision-machined gear mounted on the crankshaft that drives the timing chain or belt to synchronize the crankshaft and camshaft rotation. This ensures the engine’s valves open and close at the correct time relative to piston movement, allowing efficient combustion and preventing internal damage. A properly functioning crankshaft gear is essential for smooth engine operation and long-term reliability.

• Rattling or knocking noises from the timing area, often due to worn or damaged gear teeth.
• Engine misfires or poor performance, caused by incorrect valve timing.
• Failure to start or severe engine damage, if the gear slips or breaks completely.

In fact, many of these manufacturers have been making parts for Mercedes-Benz 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 Mercedes-Benz parts box and find an OEM branded part inside, simply with the addition of a Mercedes-Benz logo.
