Wacker Neuson 5000070990 Valve Tappet

The Wacker Neuson Valve Tappet is a genuine OEM component designed for a wide range of Wacker Neuson equipment, including CT walk-behind concrete trowels, VP and WP single-direction vibratory plates, BPU and BPS reversible vibratory plates, PT trash pumps, GP and GV portable generators, and several other engine-driven models. As a direct OEM replacement, the is manufactured to the same specification as the original part, ensuring correct fit and function across all listed platforms. This tappet is a high-cross-fitment component shared across multiple Wacker Neuson engine families, making it a practical stocking part for dealers, rental fleets, and service shops. Confirm your model and machine number against the fitment list before ordering to ensure compatibility.

Key Features

• Genuine OEM Valve Train Geometry: — Manufactured to the exact lift profile and surface hardness of the original, preserving correct valve timing and engine efficiency across all compatible models.
• Drop-In Engine Replacement: — Seats directly into the original tappet bore with no machining or shimming required, restoring the original valve-to-cam interface on reassembly.
• Broad Cross-Platform Fitment: — Compatible with CT walk-behind trowels, VP/WP/BPS/BPU vibratory plates, PT trash pumps, GP/GV generators, and additional Wacker Neuson engine-driven equipment — one part number covers an extensive range of machines.
• Protects Valves and Camshaft: — A worn or pitted tappet accelerates wear on both the valve stem and camshaft lobe, leading to loss of compression, rough running, and eventual engine damage. Replacing the tappet at the first sign of wear protects the entire valve train.
• Sourced Direct from Wacker Neuson: — Supplied as a genuine OEM part, backed by Wacker Neuson's parts program, so you can be confident the metallurgy and surface finish match what left the factory originally.

A valve tappet — also called a cam follower or lifter — sits between the camshaft lobe and the valve stem (or pushrod) inside a small engine. As the camshaft rotates, the tappet transfers that rotational motion into the linear movement needed to open and close the intake and exhaust valves at precisely the right moment. Correct valve timing is critical to engine breathing, power output, and fuel efficiency. When a tappet wears unevenly or develops pitting on its contact face, valve clearance changes, causing noisy valve train clatter, reduced compression, hard starting, and — if left unchecked — accelerated wear on both the camshaft and valve seats.
