The Wacker Neuson Valve Tappet is a genuine OEM valve tappet designed for the GB6000G, GS6000G, GS6503G, GS6500G, GS8003G, GS8000G, and GS10003G generator series. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component it replaces. As a genuine OEM part, it installs as a direct drop-in replacement with no guesswork — the correct fit for the engine configurations across these generator lines. Whether you're servicing a CE, LA, or CN variant, part number covers the full range of compatible models listed above.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Wacker Neuson's exact tappet profile and hardness specifications, ensuring consistent contact geometry between the camshaft lobe and valve stem.
- Direct Drop-In Installation — Seats into the original tappet bore without modification, maintaining the correct valve clearance straight from fitment.
- Broad Generator Series Coverage — Compatible with GB6000G, GS6000G, GS6503G, GS6500G, GS8003G, GS8000G, and GS10003G models across CE, LA, and CN configurations.
- Sustained Valve Train Performance — A correctly functioning valve tappet keeps intake and exhaust timing precise; a worn tappet causes erratic valve operation, increased engine noise, and power loss.
- Verified Part Number — Order with confidence using Wacker Neuson part number 5000408604, matched directly to your generator's parts documentation.
The valve tappet — also known as a cam follower — sits between the camshaft and the valve stem inside the engine, transmitting the rotational motion of the camshaft lobe into the linear movement that opens and closes each valve. It plays a critical role in maintaining correct valve timing, which directly affects combustion efficiency, engine power output, and fuel consumption. When a tappet wears down or loses its surface hardness, it can cause excessive valve clearance, audible ticking or clattering from the valve train, reduced compression, and ultimately poor or erratic generator performance.
