The Wacker Neuson Valve Tappet is a genuine OEM component designed for MDP3 Trash Pumps and MPU 29 Reversible Plates. Sourced directly from Wacker Neuson, this part meets the exact specifications required for correct valve train operation across the MDP3 and MPU 29 series. Using the correct OEM tappet ensures proper valve clearance is maintained, protecting the engine from premature wear. Verify your model number against the fitment list before ordering to confirm compatibility.
Key Features
- OEM Valve Geometry Compliance — Manufactured to Wacker Neuson's exact tappet profile, ensuring correct contact surface geometry between the camshaft lobe and valve stem for consistent lift performance.
- Drop-In Engine Replacement — Installs directly into the existing valve train without machining or adjustment, restoring the original valve-to-cam interface as built.
- Broad MDP3 and MPU 29 Coverage — Confirmed fitment across multiple MDP3 Trash Pump configurations and MPU 29 Reversible Plate variants, covering a wide range of Wacker Neuson small engine equipment.
- Protects Valve Train Longevity — A worn or out-of-spec tappet causes irregular valve lift, leading to loss of compression, rough running, and accelerated camshaft wear. This genuine replacement restores correct valve timing.
- Genuine Wacker Neuson Part — Supplied as an authentic OEM component, backed by Wacker Neuson's parts program for full traceability and specification confidence.
A valve tappet — also called a cam follower — sits between the camshaft and the valve stem within the engine's valve train. As the camshaft rotates, the tappet transfers the camshaft lobe's motion to open and close the intake and exhaust valves at precisely the right moment. When a tappet wears flat, develops pitting, or loses its correct profile, valve timing suffers, resulting in reduced compression, poor fuel combustion, and potential engine damage if left unaddressed. Replacing a worn tappet with the correct OEM part restores the engine's valve timing and protects the surrounding components from further wear.
