The Wacker Neuson is a genuine OEM Valve Tappet designed for a range of Wacker Neuson equipment including PTS4V centrifugal trash pumps, GPS8500 and GPS9700 portable generators, GS8.5V and GS9.7V portable generators, and the RD11V hydrostatic double drum vibratory roller. As a factory-sourced component, the meets the exact tolerances and material specifications set by Wacker Neuson for these engine-driven machines. Choosing the correct OEM Valve Tappet is critical to maintaining proper valve train geometry and long-term engine health across these platforms.
Key Features
- OEM-Spec Surface Hardness — Manufactured to Wacker Neuson's exact metallurgical standards, ensuring the tappet face withstands continuous cam lobe contact without premature wear.
- Drop-In Engine Fitment — Machined to the same profile as the original, seating directly into the valve train without adjustment or shimming.
- Broad Model Coverage — Fits PTS4V trash pumps, GPS8500 and GPS9700 portable generators, GS8.5V and GS9.7V generators, and the RD11V vibratory roller — all from a single part number.
- Protects Valve Timing Integrity — A correctly functioning tappet transfers camshaft motion cleanly to the valves; a worn tappet causes erratic valve lift, rough idling, and power loss.
- Genuine Wacker Neuson Part — Sourced directly through the Wacker Neuson OEM supply chain, so fitment and part number accuracy are confirmed against the factory bill of materials.
The valve tappet — also called a cam follower — sits between the camshaft and the valve stem (or pushrod) inside the engine. Its job is to translate the rotating motion of the camshaft lobe into the precise up-and-down movement that opens and closes the intake and exhaust valves at the right moment. Because the tappet face is under constant sliding and impact load from the camshaft, it must maintain an accurate contact surface to preserve correct valve timing and clearance. When a tappet wears, pits, or develops excessive play, the result is noisy valve train operation, reduced compression, hard starting, and ultimately accelerated wear on the camshaft itself.
