The Wacker Neuson Injection Pump is a genuine OEM component designed for the RD7H series tandem rollers and DPU 4045H and DPU 5045H diesel reversible vibratory plate compactors. As a direct OEM replacement, this injection pump is manufactured to the same standards as the original unit, ensuring proper fuel delivery and consistent engine performance across compatible machines. Fitment covers multiple RD7H configurations — including the RD7H-ES and RD7H-S — as well as the DPU 4045H and DPU 5045H vibratory plate families, making this a versatile service part for diesel-powered Wacker Neuson equipment.
Key Features
- Genuine OEM Fuel Metering Accuracy — Manufactured by Wacker Neuson as an authorized OEM part, this injection pump delivers the precise fuel metering and timing required to maintain correct combustion in the original engine configuration.
- Drop-In Replacement for Original Unit — Engineered to match the original mounting points, fuel line connections, and drive interface, this pump installs directly without rework or adaptation to the fuel system.
- Broad Diesel Equipment Fitment — Compatible with the RD7H, RD7H-ES, and RD7H-S tandem rollers, as well as the DPU 4045H and DPU 5045H diesel reversible vibratory plate compactors across multiple machine configurations.
- Sustained Engine Power Output — A correctly functioning injection pump maintains the fuel pressure and delivery cycle needed for full engine power — critical for the centrifugal force output and compaction performance of RD7H rollers and DPU 4045H/5045H plates.
- Fuel System Integrity — The injection pump is a primary component in the diesel fuel circuit; a worn or failing pump causes hard starting, rough running, loss of power, and increased fuel consumption — all of which this OEM unit is built to prevent.
The injection pump is responsible for pressurizing diesel fuel and delivering precise, timed charges to each engine injector. It is the heart of the diesel fuel system — controlling both the volume and timing of fuel injection to ensure efficient combustion and consistent engine output. When an injection pump wears or fails, symptoms include difficulty starting, uneven idling, black smoke, and a noticeable drop in machine power; replacing it with the correct OEM part restores full engine performance and protects downstream fuel system components from damage caused by irregular fuel pressure.
