Mercedes Engine Camshaft Follower - Genuine Mercedes 2820503600

Product Information

An Engine Camshaft Follower (also known as a lifter or tappet) is a small component in an internal combustion engine that sits between the camshaft and the valves. Its role is to follow the camshaft’s rotation, translating the cam’s rotational movement into the up-and-down movement that opens and closes the engine’s valves. This enables air-fuel intake and exhaust gas release, which is essential for engine operation.

• Tapping or Clicking Noise: A worn or damaged camshaft follower can cause a distinct tapping or clicking sound from the top of the engine, which is often louder when the engine is cold
• Excessive Valve Clearance: Camshaft followers that have excessive wear can cause increased clearance in the valve train, which can lead to delayed or incomplete valve opening and closing

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.
