The Wacker Neuson Injection Pump Complete is a genuine OEM component designed for the RD7Yeh LRC, RD7Yehf LRC, RD7Yehfb LRC, and RD10Yehf LRC series double drum rollers. As a factory-sourced assembly, this unit meets all original engineering standards for fuel delivery pressure, timing, and output — ensuring the engine starts reliably and runs at the correct fuel-to-air ratio under load. Confirmed fitment covers the RD7Yeh and RD10Yehf LRC model families, making it a straightforward drop-in replacement for the unit it replaces.
Key Features
- Genuine OEM Fuel Delivery Accuracy — Sourced directly from Wacker Neuson, this injection pump is built to the exact pressure and flow specifications of the original unit, maintaining correct fuel metering across the engine's full operating range.
- Direct-Fit Assembly — Supplied as a complete pump assembly with the same mounting configuration and port alignment as the original, allowing installation without adapters or machining.
- Covers Key RD-Series Roller Models — Verified fitment across the RD7Yeh LRC, RD7Yehf LRC, RD7Yehfb LRC, and RD10Yehf LRC, covering both standard and foam-filled drum variants in this compaction roller family.
- Restores Full Engine Power Output — A worn or failing injection pump starves the engine of fuel, causing hard starts, loss of compaction force, and uneven drum speed. A fresh OEM unit restores consistent power delivery from the first startup.
- Fuel System Integrity — Correct injection timing and pressure prevent unburned fuel from entering the system, protecting downstream components including injectors, nozzles, and the combustion chamber from contamination and premature wear.
The injection pump is the heart of a diesel engine's fuel system — it pressurizes fuel drawn from the tank and delivers precisely metered charges to the injectors at the correct moment in each combustion cycle. On compaction rollers like the RD7Yeh and RD10Yehf series, where consistent drum speed and sustained output are critical to achieving proper compaction, any drop in fuel delivery pressure translates directly into reduced engine performance and inconsistent compaction results. When the injection pump wears or fails, symptoms typically include hard or extended cranking, rough idle, loss of power under load, and excessive smoke — all of which signal that the pump can no longer maintain the pressure and timing the engine demands.
