The Wacker Neuson Injector is a genuine OEM component designed for the RD27-100 and RD27-120 hydrostatic vibratory tandem rollers. As a direct factory replacement, this injector meets the exact specifications required by the diesel fuel system in these machines. Sourced directly from Wacker Neuson, the ensures the combustion process performs as the original design intended, keeping your roller running at full compaction capacity across asphalt and soil applications.
Key Features
- Genuine OEM Fuel Delivery Precision — Manufactured to the exact spray pattern and flow rate specified for the RD27 diesel engine, ensuring complete and consistent fuel atomization on every injection cycle.
- Direct Drop-In Replacement — The 5000161394 installs into the same injector bore and fuel line connection as the original, requiring no modification to the fuel rail or return lines.
- Confirmed Fitment for RD27-100 and RD27-120 — Verified compatible across all four machine configurations of the RD27-100 and RD27-120 hydrostatic vibratory tandem rollers.
- Sustained Engine Output — A correctly functioning injector delivers the consistent fuel charge the engine needs to maintain drum speed and compaction force; a worn or clogged injector causes rough running, power loss, and incomplete compaction passes.
- Fuel System Integrity — OEM injector sealing and tip tolerances prevent fuel leakage into the combustion chamber or back into the fuel rail, protecting downstream engine components from contamination or dilution.
A fuel injector is responsible for delivering a precisely metered and atomized spray of diesel fuel into the engine's combustion chamber at exactly the right moment in the firing cycle. In a hydrostatic vibratory roller like the RD27 series, consistent engine power is critical — the hydrostatic drive and drum vibration systems depend on the engine maintaining steady output under load. When an injector wears, becomes clogged, or begins to drip, fuel atomization breaks down, leading to hard starts, uneven idling, black smoke, and a measurable drop in compaction performance that can compromise the quality of the finished mat or subgrade.
