Mercedes Engine Balance Shaft - Genuine Mercedes 6420300372

Product Information

A balance shaft is an eccentric weighted shaft used to control vibrations and harmonics in engines which are unnaturally balanced. The balance shaft acts as a counterweight and is weighted accordingly to oppose the harmonics caused by an unbalanced engine configuration. Balance shafts become even more critical in larger displacement engines. Since the balance shaft is part of the timing components a worn or damaged balance shaft can throw timing off causing poor engine performance or in extreme cases it can cause cylinder head damage.

• Codes between camshaft and crankshaft correlation (timing off)
• Check engine light illuminated from timing codes
• Rough idle

About Genuine Mercedes

The original parts used by Mercedes Benz to build your car are available as replacement parts under the “Genuine Mercedes Benz” brand. Manufactured under the direction of Mercedes Benz, expect excellent quality and a premium price since these parts are exclusively available through the Mercedes Benz Dealership network.

You may not realize this, but the parts that make up your Mercedes-Benz are not necessarily manufactured by Mercedes-Benz. No cause for concern, as Mercedes-Benz designs the part, hires a manufacturer, and ensures its quality to you. 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.

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.
