The Wacker Neuson 5100012259 Float is a genuine OEM component designed for the RD24-100, RD27-120, and RD28-120 series tandem rollers. As a direct OEM replacement sourced through authorized Wacker Neuson supply channels, this float is manufactured to the same specifications as the original part installed at the factory. It is compatible across a broad range of RD24, RD27, and RD28 variants including standard, combination drum, open ROPS, DPF-equipped, and electric-hybrid configurations. Keeping this component in proper working condition is essential to maintaining consistent fuel system regulation on these walk-behind and ride-on articulated tandem rollers.
Key Features
- OEM-Matched Float Construction — Manufactured to the exact buoyancy and dimensional tolerances of the original, ensuring consistent fuel level regulation within the carburetor bowl.
- Drop-In Replacement — Engineered to seat and connect within the carburetor assembly the same way as the factory-installed float, with no reworking of the fuel bowl or needle valve seat required.
- Broad RD-Series Compatibility — Confirmed fitment across more than 35 RD24-100, RD27-120, and RD28-120 tandem roller configurations, including DPF, combination drum, open ROPS, US-spec, and electric-hybrid variants.
- Fuel Flow Stability — A correctly functioning float maintains the proper fuel level in the carburetor bowl; a worn or damaged float can cause flooding, lean running, or hard starting that interrupts compaction operations.
- Genuine Wacker Neuson OEM Part — Supplied under part number 5100012259 directly within the Wacker Neuson OEM parts network, giving you confidence in part authenticity and fitment accuracy.
The float is a small but critical component inside the carburetor's fuel bowl. It rises and falls with the fuel level, opening and closing the needle valve to maintain a consistent fuel supply to the engine. When the float is cracked, saturated, or bent out of position, it can no longer regulate fuel level accurately — leading to an overly rich or lean fuel mixture, rough running, stalling, or fuel flooding into the engine. Replacing a faulty float restores proper carburetion and keeps the engine running at the correct air-fuel ratio for consistent power output during compaction work.
