The Wacker Neuson is a genuine OEM Water Tank Cap designed for a wide range of Wacker Neuson RD-series tandem rollers and CRT-series ride-on concrete trowels. Sourced directly from Wacker Neuson, this cap is the factory-correct replacement for machines including the RD12, RD16, RD7H, CRT36, CRT48, and CRT60 series. Because it is a genuine OEM component, it matches the original part in thread pitch, material grade, and sealing profile — no guesswork on fit. Keeping the water tank properly sealed is essential to maintaining the drum-wetting or blade-cooling systems these machines depend on during operation.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's exact thread and seal specification, ensuring the water tank closes and vents correctly without leaks or pressure loss.
- Direct Thread-Match Replacement — Threads directly onto the OEM water tank fitting on RD-series tandem rollers and CRT-series ride-on trowels with no modification to the tank neck or fittings.
- Broad Cross-Series Fitment — Compatible with RD7H, RD12, RD12A, RD16 tandem rollers and CRT36, CRT48, and CRT60 ride-on trowel families, covering a wide range of Wacker Neuson equipment in a single part number.
- Protects Water System Function — A damaged or missing tank cap allows contaminants into the water supply and disrupts flow to drum sprayers or trowel cooling circuits, leading to uneven results and accelerated component wear.
- Verified Part Number 5000164776 — Cross-reference against your machine's serial number and parts manual to confirm fitment before ordering.
The water tank cap seals the onboard water reservoir found on tandem rollers and ride-on trowels, keeping the supply clean and the system pressurized correctly for consistent flow to drum-wetting spray bars or surface-cooling circuits. On tandem rollers such as the RD12 and RD16, an intact cap prevents debris from entering the tank and ensures the spray system can properly wet the drums to prevent asphalt pickup during compaction passes. On CRT-series ride-on trowels, the same water supply supports blade lubrication and surface finishing — a compromised cap can interrupt that flow, affect surface quality, and introduce contamination that shortens pump and nozzle life.
