The Wacker Neuson 5100031895 is a genuine OEM Fuel Injection Pump designed for the RD7Ye, RD7Yeh LRC, RD7Yehf LRC, RD7Yehfb LRC, and RD10Yehf LRC walk-behind tandem rollers. As a direct OEM replacement, part 5100031895 is manufactured to the same specifications as the original component installed at the factory, ensuring a correct, direct-fit installation into your machine's fuel system. This pump is the right choice when restoring full compaction performance to your tandem roller after fuel delivery issues or a pump failure. Verify your machine's model and serial number against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Fuel Delivery Precision — Built to exact injection timing and pressure specifications for Wacker Neuson diesel tandem rollers, ensuring consistent fuel atomization and combustion efficiency.
- Direct-Fit Installation — Matches the original pump's mounting profile, port configuration, and fuel line connections for a straightforward swap with no adaptation needed.
- Broad RD-Series Compatibility — Fits multiple configurations across the RD7Ye and RD10Yehf LRC walk-behind tandem roller families, covering a wide range of serial number ranges.
- Protects Engine Performance — A functioning injection pump delivers the correct fuel charge at the right moment; a worn or failing pump causes hard starting, rough running, loss of power, and incomplete compaction passes.
- Fuel System Integrity — Using a genuine OEM pump maintains the integrity of the closed fuel system, reducing the risk of unmetered fuel delivery that can damage injectors or cause excess emissions.
The fuel injection pump is responsible for pressurizing and metering diesel fuel, then delivering it to the injectors at precisely the right moment in the engine's combustion cycle. On a walk-behind tandem roller like the RD7Ye or RD10Yehf LRC, consistent engine output is critical — the drum vibration system and travel drive both depend on steady power from the diesel engine. When the injection pump wears or fails, symptoms typically include difficulty starting, uneven idle, black or white exhaust smoke, and a noticeable drop in drum compaction force, all of which can compromise the quality of the finished compacted surface.
