The Wacker Neuson Tappet is a genuine OEM component designed for the RD12-90 Double Drum Roller and CRT36-25 Ride-on Trowel series. As a factory-sourced part, it meets the exact tolerances and material specifications set by Wacker Neuson for these machines. The fits across multiple configurations of the RD12-90 and CRT36-25, including solid ROPS, foldable ROPS, and wheel kit variants, making it a straightforward replacement for machines across both product lines.
Key Features
- OEM-Spec Surface Hardness — Manufactured to the precise hardness and profile tolerances required for correct valve train operation, ensuring consistent contact and wear characteristics over the service life of the part.
- Drop-In Replacement — Engineered to the same dimensions as the original, seating directly into the valve train without adjustment or rework during installation.
- Broad Model Coverage — Fits the RD12-90 Double Drum Roller (solid and foldable ROPS variants) and the CRT36-25 Ride-on Trowel (including wheel kit and standard configurations) under a single part number.
- Smooth Valve Actuation — A correctly functioning tappet maintains accurate valve timing and lift, supporting stable engine output and efficient combustion across demanding compaction and finishing applications.
- Genuine Wacker Neuson Part — Sourced directly through the Wacker Neuson OEM supply chain, so you receive the same component installed at the factory — not an approximation of it.
A tappet — also known as a valve lifter — sits between the camshaft and the valve stem (or push rod) inside the engine's valve train. As the camshaft rotates, the tappet follows the cam lobe's profile and transfers that motion to open and close the intake and exhaust valves at precisely the right moment. When a tappet wears, becomes pitted, or loses its correct profile, valve timing drifts, combustion efficiency drops, and the engine can develop a characteristic tapping or knocking noise. Left unaddressed, a worn tappet accelerates wear on adjacent valve train components and can lead to more extensive engine damage.
