The Wacker Neuson Valve Tappet Spring is a genuine OEM component designed for a range of Wacker Neuson ride-on trowels, tandem rollers, floor saws, and portable generators. As a direct OEM replacement, this spring is manufactured to the original specification, ensuring correct tension and fitment within the valve train assembly. Confirmed fitment includes the CRT36-24A ride-on trowel series, RD12A-90 and RD11A tandem rollers, BFS 2020AS floor saw, and GS12Ai generator, among others. Verifying part number against your machine's serial number before ordering is always recommended.
Key Features
- Correct Spring Rate for Valve Train Integrity — engineered to the original tension specification so the tappet operates within the engine's designed valve-lift parameters.
- Genuine OEM Sourcing — produced by Wacker Neuson and supplied through the authorized parts channel, matching the spring installed at the factory.
- Broad Cross-Family Fitment — compatible across multiple Wacker Neuson product families, including CRT36-24A ride-on trowels, RD12A-90 and RD11A tandem rollers, BFS 2020AS floor saw, and the GS12Ai portable generator.
- Drop-In Replacement — matches the original mounting position and seat diameter, allowing a straightforward swap during routine valve-train service without secondary modification.
- Protects Against Valve Float and Misfiring — a worn or broken tappet spring can cause inconsistent valve seating, leading to loss of compression, rough running, or engine damage; replacing it promptly restores normal combustion.
A valve tappet spring sits within the engine's valve train and applies the return force needed to close each valve fully after it has been pushed open by the camshaft. Without sufficient spring tension, valves can hang open or bounce — a condition known as valve float — which disrupts the engine's compression cycle and can cause misfiring, power loss, or accelerated wear on the valve seats and guides. Replacing a fatigued or broken tappet spring restores the correct valve timing and sealing, allowing the engine to run at full power and efficiency.
