The Wacker Neuson Valve Spring is a genuine OEM component designed for the RD12-90 double drum roller series, CRT36-25 ride-on trowels, and BFS and BFSX floor saw lines. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component it replaces, ensuring a correct, drop-in installation with no guesswork. It is a direct fit across a wide range of Wacker Neuson equipment, covering petrol and diesel floor saw variants including the BFS18, BFS20, BFSX18, BFSX20, BFS 1345B, BFS 1350L, and BFS 130R series, as well as the RD12-90 tandem roller configurations and CRT36-25 trowel platforms with and without wheel kits.
Key Features
- OEM Spring Tension Accuracy — Manufactured to the original valve spring rate specification, ensuring the valve opens and closes at the correct pressure point for consistent engine performance.
- Direct Drop-In Replacement — Engineered to seat and compress identically to the factory part, allowing straightforward installation without modification to the valve train or surrounding components.
- Broad Wacker Neuson Fitment — Compatible with RD12-90 rollers, CRT36-25 ride-on trowels, and the full BFS and BFSX floor saw family across petrol and diesel configurations.
- Restores Proper Valve Sealing — A fatigued or broken valve spring causes erratic idling, power loss, and poor compression; replacing it with a correctly rated OEM spring restores consistent combustion and throttle response.
- Fuel System Integrity — Correct spring tension is essential to maintaining proper valve timing and preventing unmetered fuel or air bypass that can affect engine output and emissions compliance.
A valve spring holds the engine or fuel system valve firmly against its seat when closed, and returns it to the closed position after each opening cycle. When the spring loses tension through fatigue, corrosion, or breakage, the valve can float, fail to seal completely, or stick — leading to compression loss, rough running, and accelerated wear on surrounding valve train components. Replacing a worn valve spring promptly with a correctly rated OEM part is one of the most cost-effective ways to restore stable engine operation and protect the integrity of the cylinder head or carburetor assembly it serves.
