The Wacker Neuson Water Tank is a genuine OEM component designed for the RD7 series walk-behind tandem rollers, including the RD7H-ES and RD7H-S models. Sourced directly from Wacker Neuson, this tank is an exact match to the original unit installed at the factory — no guesswork on fitment or compatibility. It is confirmed to fit multiple RD7 configurations, including EU-spec and standard variants across both the RD 7ES and RD 7S model lines.
Key Features
- OEM-Grade Tank Construction — Manufactured to the same material and dimensional standards as the original, ensuring proper seal, capacity, and connection alignment on RD7 series rollers.
- Direct-Fit Replacement — Mounts to the same attachment points as the factory tank, connecting directly to the existing water distribution system without rework or adaptation.
- Broad RD7 Series Coverage — Compatible with RD7H-ES, RD7H-S, RD7H, and RD7-RAW configurations, covering both EU and standard market builds of the walk-behind tandem roller lineup.
- Supports Consistent Drum Wetting — A properly functioning water tank keeps the drums evenly wetted during asphalt compaction, preventing material pickup and ensuring a clean, consistent pass.
- Genuine Wacker Neuson Part — Part number 5000112144 is an authentic OEM component, providing the correct capacity and port dimensions to maintain the roller's water system as designed.
The water tank on a walk-behind tandem roller stores the clean water that is continuously fed to the drum surfaces during asphalt compaction. Keeping the drums wet prevents hot asphalt from sticking to the steel drums, which would otherwise cause tearing and surface defects on the mat. When the tank cracks, leaks, or its outlet fittings fail, water flow to the drums is interrupted — leading to material buildup on the drums and a compromised finish on the paved surface. Replacing a damaged tank promptly restores the water system to full function and protects the quality of the compacted mat.
