The Wacker Neuson 5100012013 Float is a genuine OEM component designed for RD40-130 and RD45-140 series tandem rollers. As a direct OEM replacement, this float is sourced to the exact specification used in original production, ensuring it seats, seals, and functions correctly within the fuel system. This part covers an extensive range of RD40-130 and RD45-140 variants, including C, O, DPF, and.3 configurations across both US and standard market builds. Keeping the correct float in service is essential to maintaining accurate fuel delivery and consistent machine operation on the job.
Key Features
- Genuine OEM Construction — Manufactured to the exact material and dimensional tolerances specified for the carburetor fuel system on Wacker Neuson tandem rollers, ensuring correct buoyancy and needle valve actuation.
- Drop-In Replacement — Installs directly into the existing carburetor float bowl with no modification to mounting hardware or fuel inlet components.
- Broad RD-Series Fitment — Confirmed for the full RD40-130 and RD45-140 families, including C, O, DPF, and .3 variants in both standard and US-spec configurations.
- Protects Fuel Metering Accuracy — A correctly functioning float maintains the proper fuel level in the float bowl, preventing the rich or lean running conditions caused by a waterlogged or damaged float.
- Fuel System Integrity — Using the correct OEM float minimizes the risk of fuel overflow or fuel starvation, both of which can lead to unplanned engine shutdowns on active compaction sites.
The float is a small but critical component inside the carburetor float bowl. Its job is to rise and fall with the fuel level, opening and closing the needle valve to regulate how much fuel enters the carburetor. When the float is at the correct level, the engine receives a consistent, properly metered fuel-air mixture. If the float becomes saturated, cracked, or deformed, it can no longer regulate fuel level accurately — causing the engine to run too rich, flood, or lose power under load. Replacing a faulty float restores correct fuel metering and prevents the fuel delivery issues that lead to hard starting, rough running, or engine damage on Wacker Neuson RD-series tandem rollers.
