The Wacker Neuson 5100023485 is a genuine OEM Fuel Pump designed for a broad range of Wacker Neuson single-drum soil compactors and tandem rollers, including the RC50, RC70, RC70VO, RD18, RD24, RD27, and RD28 series. As a direct OEM replacement, this fuel pump is manufactured to the same specification as the original unit, ensuring correct fuel delivery and consistent engine operation across all covered models. The 5100023485 fits an extensive range of configurations including smooth drum, padfoot, DPF ROPS, DPF CAB, and US-market variants, making it a single verified solution for mixed fleets. Always confirm your machine's model number and serial number before ordering to ensure accurate fitment.
Key Features
- Genuine OEM Fuel Delivery Spec — Built to the same flow rate and pressure output as the original pump, ensuring the engine receives consistent fuel supply under load.
- Direct-Fit Installation — Matches the original mounting configuration and fuel line connections, allowing straightforward swap-out with standard hand tools.
- Wide Model Coverage — Compatible with RC50, RC50P, RC70, RC70P, RC70VO single-drum soil compactors and RD18, RD24, RD27, and RD28 tandem rollers across smooth drum, padfoot, ROPS, and CAB variants.
- Protects Engine Performance — A failing fuel pump starves the engine of fuel, causing hard starts, loss of power, and uneven compaction output; replacing it restores full operating capability.
- Fuel System Integrity — OEM construction ensures correct sealing at all connection points, reducing the risk of fuel leaks in a safety-critical system.
The fuel pump draws diesel from the tank and delivers it at the correct pressure to the engine's injection system. Without adequate fuel supply, the engine cannot maintain the power needed to drive compaction forces through the drum — resulting in rough running, stalling, or failure to start. On heavy-duty compaction machines like the RC and RD series, where consistent drum energy is critical to achieving specified compaction density, a worn or failed fuel pump will directly compromise output quality and machine availability.
