The Wacker Neuson Spring Weight Return is a genuine OEM component designed for a wide range of Wacker Neuson equipment, including the RD12A-90 tandem rollers, CRT36-26A and CRTv36-26A trowels, BFS 2020AS saw, GS12Ai, and GPS9700A. As a factory-sourced part, the is manufactured to the exact material and dimensional standards of the original, ensuring a consistent, trouble-free installation. Sourcing genuine OEM means you get the same part that left the factory — no guesswork, no adaptation required. Confirm fitment against your machine's model number before ordering to ensure this is the correct spring for your application.
Key Features
- Genuine OEM Spring Tension Spec — Manufactured to the original return-force rating, so the spring delivers the correct load cycle every time without over- or under-tensioning the weight mechanism.
- Direct Drop-In Replacement — Matches the original mounting points and hook geometry of the 5000226427, allowing straightforward removal and reinstallation without reworking surrounding components.
- Broad Equipment Compatibility — Fits the RD12A-90 double drum roller series, CRT36-26A and CRTv36-26A trowels, BFS 2020AS saw, GS12Ai, and GPS9700A from a single part number.
- Restores Consistent Weight Return Action — A fatigued or broken return spring causes erratic weight movement and uneven compaction or finishing performance; replacing it with this OEM part restores smooth, repeatable operation.
- Genuine Wacker Neuson Part — Sourced directly through the Wacker Neuson OEM supply chain, so the material grade, wire diameter, and coil specification match the original assembly exactly.
A spring weight return controls the rebound and reset motion of the weight assembly within the machine, pulling it back to its neutral position after each cycle so the next stroke begins from a consistent starting point. When this spring weakens, cracks, or breaks, the weight fails to return fully or reliably, leading to inconsistent output — whether that's uneven drum compaction on a roller or irregular finishing passes on a trowel. Replacing a worn spring weight return promptly keeps the machine operating within its designed rhythm and prevents secondary wear on connected components caused by uncontrolled weight movement.
