The Wacker Neuson Water Tank Cap is a genuine OEM component designed for the RD27-100 and RD27-120 series hydrostatic vibratory rollers, including standard and traction control configurations. As a direct Wacker Neuson OEM part, the is manufactured to the same specifications as the original, ensuring a proper seal and fit on the water tank. Verified fitment spans multiple machine numbers across the RD27-100 and RD27-120 roller families, making this a straightforward, confidence-inspiring replacement for operators and service technicians alike.
Key Features
- Genuine OEM Sealing Integrity — Engineered to maintain an airtight, pressure-appropriate seal on the water tank, preventing evaporation loss and contamination that can compromise the roller's water ballast system.
- Direct-Fit Replacement — Threaded or latched to match the original tank opening on RD27-series rollers, dropping straight into place without modification to the tank neck or mounting point.
- Broad RD27 Series Coverage — Confirmed fitment across RD27-100 and RD27-120 hydrostatic vibratory rollers in both standard and traction control variants.
- Protects Water System Performance — A damaged or missing tank cap allows debris and moisture contamination into the water system, which can disrupt drum wetting consistency and lead to asphalt sticking during compaction passes.
- Sourced from Wacker Neuson — Supplied as a genuine OEM part, carrying the same part number — 5000162314 — as what was installed at the factory, so there is no guesswork on compatibility.
The water tank cap seals the onboard water reservoir used to wet the compaction drums on vibratory rollers during asphalt work. Keeping the drums moist prevents hot asphalt from sticking to the drum surface, which is critical to achieving a smooth, even mat. When the cap is cracked, missing, or no longer sealing correctly, the tank loses water faster than expected, the drum surface dries out mid-pass, and mix adhesion becomes a real problem on the job. Replacing a worn cap promptly keeps the water system functioning as intended and protects the quality of the compacted surface.
