The Wacker Neuson Injection Pump Complete is a genuine OEM fuel injection pump assembly designed for DPU 2440H, DPU 2450H, and DPS 1850H series vibratory plate compactors. As a direct OEM replacement, this complete assembly is sourced from Wacker Neuson and built to the same specification as the original unit installed at the factory. Whether you're servicing a reversible DPU model used for heavy-duty soil and aggregate compaction or a DPS 1850H configured for asphalt work, part number ensures a direct, compatible fit. Keeping the injection pump in proper working order is critical to maintaining consistent engine output and reliable plate performance in the field.
Key Features
- Calibrated Fuel Delivery: — Built to OEM specification for precise metered fuel delivery, ensuring correct injection timing and volume for consistent diesel engine performance.
- Complete Assembly: — Supplied as a full Injection Pump Complete unit, so all internal components arrive pre-assembled and ready to install as a matched set.
- Broad DPU and DPS Fitment: — Confirmed for DPU 2440H, DPU 2450H, and DPS 1850H vibratory plate compactors, covering both reversible and single-direction diesel plate models.
- Genuine OEM Part: — Sourced directly from Wacker Neuson, this part carries the same part number — 5000108818 — as the original, so there's no guesswork on compatibility.
- Engine Protection: — A worn or failing injection pump causes hard starting, erratic RPM, and loss of compaction force; replacing it with the correct OEM unit restores full power delivery and protects the engine from lean-run damage.
- Fuel System Integrity: — Correct injection pressure and sealing are critical to safe diesel operation; an OEM-spec pump maintains system pressure within design limits and prevents uncontrolled fuel leaks.
The injection pump is the heart of a diesel fuel system — it pressurizes and meters fuel from the tank and delivers precisely timed injections to the engine's combustion chamber. On diesel-powered vibratory plate compactors like the DPU 2440H and DPS 1850H, a properly functioning injection pump directly controls engine speed, power output, and throttle response. When the pump wears out or fails internally, symptoms typically include difficult cold starting, uneven idling, black or white exhaust smoke, and a noticeable drop in plate compaction force — all of which point to degraded or mistimed fuel delivery.
