The Wacker Neuson Spring is a genuine OEM component designed for the RD40-130 and RD45-140 series tandem rollers, including standard, c, o,.3, and DPF variants. As a direct OEM part, it is manufactured to the exact specifications required by Wacker Neuson, ensuring correct tension, load characteristics, and dimensional fit within the machine. This spring covers an extensive range of RD-series roller configurations, making it a go-to replacement for fleet operators running multiple variants across jobsites.
Key Features
- OEM-Spec Tension and Load Rating — Manufactured to Wacker Neuson's exact spring rate specifications, so the part delivers the correct mechanical response every time it is installed.
- Direct Drop-In Replacement — Engineered to the same dimensions and mounting configuration as the original, allowing straightforward installation without modification to surrounding components.
- Broad RD-Series Compatibility — Fits RD40-130 and RD45-140 tandem rollers across standard, c, o, .3, and DPF variants, covering a wide range of production runs in a single part number.
- Sustained Mechanical Function — A correctly functioning spring maintains proper component engagement and return action; a worn or broken spring can lead to inconsistent operation or component contact failures.
- Genuine Wacker Neuson Part — Sourced directly through authorized Wacker Neuson supply channels, so you get the same part that left the factory — not an approximation of it.
A spring in a tandem roller serves as a mechanical return or tensioning element, maintaining consistent force between connected components throughout the machine's operating cycle. When a spring loses tension, takes a set, or breaks, the components it controls may not return to their correct position, leading to erratic performance or accelerated wear on adjacent parts. Replacing a fatigued spring promptly with the correct OEM part restores the intended mechanical relationship and keeps the roller performing as designed.
