The Wacker Neuson 5100031902 Fuel Limiter Complete is a genuine OEM assembly designed for the RD7Ye tandem roller. Sourced directly from Wacker Neuson, this part carries the same specifications as the original component installed at the factory. It is confirmed to fit multiple RD7Ye configurations, including walk-behind roller variants covered under that model family.
Key Features
- Genuine OEM Fuel Metering Precision — Exact fuel delivery tolerances maintained, ensuring the engine receives the correct fuel quantity under all operating loads.
- Drop-In Assembly — Supplied as a complete unit, the 5100031902 installs directly into the existing fuel system without sourcing individual sub-components.
- Verified RD7Ye Compatibility — Confirmed fitment across RD7Ye tandem roller and walk-behind roller configurations within the RD7Ye model family.
- Protects Engine from Over-Fueling — A properly functioning fuel limiter prevents excess fuel delivery that can cause black smoke, power loss, and accelerated engine wear on the roller.
- Fuel System Integrity — Using a genuine OEM limiter assembly maintains correct injection system calibration, which is critical for emissions compliance and consistent compaction performance.
The fuel limiter is a governing component within the engine's fuel delivery system that caps the maximum quantity of fuel injected during each combustion cycle. It prevents the engine from being over-fueled under high load conditions, which protects internal components and keeps combustion clean and efficient. When a fuel limiter fails or wears, operators typically see excessive smoke, erratic power output, and elevated engine temperatures — all of which directly compromise compaction output and machine longevity on the RD7Ye tandem roller.
