The Wacker Neuson Injection Valve Complete is a genuine OEM component designed for the DPU 5045H and DPU 4045H series reversible vibratory plate compactors. As a direct Wacker Neuson OEM part, the is manufactured to the same specification as the original, ensuring a correct fit within the diesel fuel system of these heavy-duty reversible plates. This part is confirmed compatible with multiple build variants of the DPU 5045H and DPU 4045H, making it the reliable choice when servicing this compactor family.
Key Features
- Genuine OEM Fuel System Precision — Manufactured to Wacker Neuson's exact injection tolerances, ensuring correct fuel atomization and delivery pressure that a worn or leaking valve would compromise.
- Direct-Fit Replacement — Engineered as a complete valve assembly, so it installs directly into the existing fuel injection circuit without adaptation or modification to the fuel line connections.
- Confirmed DPU Fitment — Compatible with DPU 5045H and DPU 4045H reversible vibratory plate compactors, covering both standard and 750-series build configurations.
- Protects Engine Performance — A properly functioning injection valve maintains consistent fuel metering; a failed or stuck valve can cause hard starting, rough running, or excessive fuel consumption in diesel-powered compaction equipment.
- Fuel System Safety — As a pressurized fuel system component, using a correctly rated OEM valve helps maintain seal integrity and reduces the risk of fuel leaks during operation.
The injection valve complete controls the precise delivery of diesel fuel into the engine's combustion chamber by opening and closing under high pressure to meter fuel at the correct moment in the engine cycle. On diesel-powered reversible plate compactors like the DPU 5045H and DPU 4045H, consistent fuel injection directly affects starting reliability, engine smoothness, and compaction output. When the injection valve wears, sticks, or develops an internal leak, the result is typically poor starting performance, uneven engine idle, increased fuel consumption, or visible black smoke — all signs that the valve assembly needs to be replaced.
