The Wacker Neuson Additive Tank is a genuine OEM component designed for the RD24-100 and RD27-120/RD28-120 series tandem rollers, including DPF and electric variants. Sourced directly from Wacker Neuson, this part carries the same specifications as the original unit installed at the factory, ensuring a correct, direct fit without the guesswork. The covers an extensive range of RD-series models — from early C and C.3 configurations through to current RD24-100ce and RD28-120ce electric machines — making it the go-to solution for operators maintaining rollers across a mixed fleet.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original material and dimensional specifications, so the tank seats, seals, and connects exactly as the unit it replaces.
- Broad RD-Series Compatibility — Fits RD24-100 and RD28-120/RD27-120 tandem rollers across C, C.3, o.3, DPF, and ce (electric) model variants.
- Direct Drop-In Replacement — Matches OEM mounting points and connection interfaces on supported machines, allowing a straightforward swap during routine maintenance or unplanned repair.
- Protects Compaction Performance — A fully functional additive tank ensures the water-spray system receives the correct additive dosing, preventing asphalt and soil from sticking to the drum and maintaining clean, consistent compaction passes.
- Verified Part Number — Order with confidence: part number 5100066876 is the current Wacker Neuson catalog reference for this tank across all listed model configurations.
The additive tank on a tandem roller stores the water-spray additive used to prevent the steel drums from picking up material during compaction — particularly critical when working asphalt. It feeds the drum wetting system so each pass releases cleanly, protecting surface finish and drum condition. When the tank cracks, leaks, or its fittings fail, the spray system loses pressure or shuts down entirely, leading to drum contamination, uneven mat texture, and accelerated wear on the drum surface.
