The Wacker Neuson 5100017981 is a genuine OEM Gas Spring designed for RD40-130 and RD45-140 series tandem rollers. This part is sourced directly from Wacker Neuson, ensuring an exact fit across the full range of RD40-130 and RD45-140 configurations — including standard, combination (c), open-drum (o), DPF, and.3-series variants. Whether you're servicing a machine on a highway paving crew or a commercial asphalt site, this OEM replacement maintains the precise resistance and travel characteristics the original design requires. Confirm your model and machine number against the fitment list before ordering to ensure compatibility with your specific unit.
Key Features
- Genuine OEM Damping Specification — Matched to the exact compression force and extension rate engineered for the RD40-130 and RD45-140 platforms, so hood or canopy movement stays controlled and predictable.
- Drop-In Replacement — Mounts to the original attachment points with no modification to brackets or hardware; retains factory pivot geometry throughout its travel range.
- Broad RD-Series Coverage — Fits a wide range of RD40-130 and RD45-140 configurations, including standard, open-drum, combination, DPF-equipped, and .3-generation models across US and international variants.
- Sustained Hold Force — A properly functioning gas spring holds hoods and access panels securely in the open position during service and inspection, protecting technicians from unexpected closure.
- Operator and Technician Safety — A weakened or failed gas spring can allow heavy engine covers to drop without warning; replacing with the correct OEM unit restores the intended safety hold.
A gas spring is a sealed pneumatic strut that uses compressed gas — typically nitrogen — to generate a controlled, consistent push or pull force across its stroke. On Wacker Neuson tandem rollers like the RD40-130 and RD45-140 series, gas springs support engine compartment hoods and access panels, holding them securely open during routine maintenance and inspection. When a gas spring loses pressure or its seals degrade, the panel it supports can drift or fall unexpectedly, creating a safety hazard and making service work significantly more difficult.
