The Wacker Neuson Jet is a genuine OEM component designed for the RD7H series tandem rollers and DPU 4045H and DPU 5045H series diesel reversible vibratory plate compactors. As a direct OEM part, the is manufactured to the same specification as the original, ensuring it seats and functions exactly as intended within the fuel system. This jet fits multiple RD7H variants — including the RD7H-ES and RD7H-S — as well as the DPU 4045H and DPU 5045H, including the DPU 5045He US configuration. If your machine's fuel delivery or carburetor circuit is underperforming, verifying the condition of the jet is an important first step.
Key Features
- Calibrated OEM Orifice Size — Manufactured to the original fuel-metering specification, ensuring the correct fuel-to-air ratio is maintained through the carburetor circuit.
- Direct OEM Replacement — Drops into the existing carburetor assembly without modification; matches the original thread form, body diameter, and port sizing of the factory-installed jet.
- Broad Fitment Across Two Machine Families — Compatible with RD7H, RD7H-ES, and RD7H-S tandem rollers, plus DPU 4045H and DPU 5045H diesel reversible plate compactors, including the DPU 5045He US variant.
- Consistent Fuel Delivery Under Load — A correctly sized jet keeps the engine running at the designed fuel mixture during compaction cycles, preventing rich or lean conditions that cause power loss or stalling.
- Fuel System Integrity — A worn or clogged jet disrupts metered fuel flow, leading to hard starting, rough idle, and inconsistent engine output — replacing it restores proper carburetor function.
A jet is a precisely drilled metering component fitted inside a carburetor that controls the volume of fuel entering the engine's air-fuel mixture. The diameter of the jet's orifice is calibrated to deliver the exact fuel quantity the engine needs at a given throttle position and load. When a jet becomes clogged with fuel varnish or debris, or is physically worn, the fuel mixture is thrown off — causing symptoms like hard starting, erratic idle, loss of power under load, or excessive fuel consumption. Replacing a faulty jet with the correct OEM-spec part restores precise fuel metering and returns the engine to its designed operating performance.
