The Wacker Neuson Tappet is a genuine OEM component designed for the G40, G50, G60, G70, G95, and G110 series portable generators. Sourced directly from Wacker Neuson, this tappet meets the exact material and dimensional standards of the original part. It is a direct-fit replacement for a wide range of G-series mobile generator configurations, including standard, premium, and LATAM market variants. Keep your generator's valve train operating within spec by replacing worn or damaged tappets with the correct OEM part.
Key Features
- Genuine OEM Valve Train Geometry: — Machined to the exact profile and hardness spec of the original, ensuring correct valve lift and timing across the G-series engine family.
- Drop-In Engine Compatibility: — Seats directly into the original tappet bore without reworking or shimming, maintaining correct valve-to-camshaft contact geometry.
- Broad G-Series Fitment: — Confirmed for G40, G50, G60, G70, G95, and G110 generators, covering standard, mobile, premium, and LATAM-market configurations.
- Protects Against Power Loss and Rough Running: — A worn tappet causes improper valve actuation, leading to misfires, loss of output, and accelerated engine wear; replacing it restores smooth combustion and rated power delivery.
- Verified Wacker Neuson Part Number: — Part number 5200021377 is the authoritative OEM reference for this application — use it to confirm fitment before ordering.
A tappet — also called a valve lifter — sits between the camshaft and the valve stem (or pushrod) inside the engine. As the camshaft rotates, the tappet translates that rotational motion into the linear movement needed to open and close the intake and exhaust valves at precisely the right moment. When a tappet wears, develops pitting on its contact face, or loses proper clearance, valve timing is disrupted — resulting in rough idling, reduced power output, increased fuel consumption, and potential damage to surrounding valve train components. Replacing a worn tappet promptly with a correctly specified part restores proper combustion cycles and protects the engine from further internal damage.
