The Wacker Neuson Water Tank is a genuine OEM component designed for the RD18-80, RD18-100, and RD18-100c series double drum rollers. As a direct OEM part, it is manufactured to the same standards as the original, ensuring a straight-swap installation with no adaptation needed to mounts or fittings. This part also covers the updated RD18-80.3, RD18-100.3, and RD18-100c.3 model variants, making the correct replacement across the full RD18 roller lineup. Ordering the right part number the first time keeps your machine running to spec and your compaction work on schedule.
Key Features
- OEM-Spec Tank Construction — Built to hold and deliver the precise water volume required for effective drum wetting, with material thickness and sealing surfaces matching the original Wacker Neuson specification.
- Drop-In Installation — Mounts directly to the original bracket points and connects to existing feed lines without rerouting or adapting hardware, making replacement straightforward in the field.
- Broad RD18 Series Coverage — Confirmed fitment across six RD18 roller models: RD18-80, RD18-100, RD18-100c, RD18-80.3, RD18-100.3, and RD18-100c.3.
- Consistent Drum Wetting Performance — A sound water tank maintains steady flow to the drum wetting system, preventing material pickup and asphalt sticking during compaction passes.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, so part number 5100058615 carries full OEM traceability and is the same component used in original assembly.
The water tank on a double drum roller supplies water to the drum wetting system, which keeps the drums lightly coated during asphalt and aggregate compaction passes. This continuous film prevents hot mix from adhering to the drum surface, which would otherwise cause tearing and uneven compaction. A cracked, leaking, or failed water tank starves the wetting system, leading to material buildup on the drum and a compromised finish on the mat.
