The Wacker Neuson 5000164776 is a genuine OEM Water Tank Cap designed for a broad range of Wacker Neuson RD-series tandem rollers and CRT-series ride-on concrete trowels. Sourced directly from Wacker Neuson, this cap carries the same part number and specification as the component installed at the factory. It fits confirmed machine configurations across the RD7, RD12, RD16, CRT36, CRT48, and CRT60 series, making it a dependable go-to when servicing multiple machine types on the same fleet. Verify your machine model and serial number against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Sealing Specification — Manufactured to the exact thread profile and seal geometry required by the Wacker Neuson water tank, ensuring a pressure-retaining closure without improvised workarounds.
- Direct Drop-In Replacement — Threads directly onto the original tank filler neck; no adapters or modifications to the tank opening are required.
- Broad Fleet Coverage — Confirmed fitment across RD7, RD12, RD12A, RD16 tandem rollers and CRT36, CRT48, and CRT60 ride-on concrete trowels, covering both standard and Power Steer configurations.
- Protects the Water System — A properly sealing cap prevents dirt, debris, and contaminants from entering the water tank, which protects spray nozzles, pump screens, and drum-wetting components from premature wear.
- Prevents Fluid Loss — A worn or cracked cap allows water to escape during operation, leading to dry drum surfaces, uneven compaction or finishing, and unplanned stops to refill mid-shift.
The water tank cap seals the filler opening on the machine's onboard water tank, which supplies water to the drum-wetting or surface-wetting system. On tandem rollers, this system keeps the drums moist to prevent asphalt from sticking during compaction passes. On ride-on trowels, water is used for cooling and surface conditioning during the finishing process. When the cap is damaged, missing, or no longer seals correctly, the tank loses water through evaporation or spillage, contaminants can enter the system, and spray components downstream can clog or wear prematurely — all of which interrupt the work cycle and add unnecessary maintenance cost.
