The Wacker Neuson 5100031845 is a genuine OEM Rocker Arm designed for the RD7Ye and RD10Yehf series walk-behind tandem rollers. Sourced directly from Wacker Neuson, this part meets the exact engineering tolerances specified for these machines, ensuring proper valve train geometry and consistent engine performance. It is confirmed to fit multiple RD7Ye and RD7Yeh configurations — including LRC and HRC variants — as well as the RD10Yehf LRC, making it a versatile solution across the RD7 and RD10 roller families.
Key Features
- OEM Valve Train Precision — Manufactured to Wacker Neuson's exact rocker arm geometry, ensuring correct valve lift, timing, and contact with the camshaft and valve stem.
- Drop-In Engine Fitment — Engineered to install directly onto the existing rocker arm shaft without modification, maintaining proper pivot clearance and alignment.
- Broad RD7 and RD10 Compatibility — Fits multiple RD7Ye, RD7Yeh, RD7Yehf, RD7Yehfb, and RD10Yehf tandem roller configurations, covering both LRC and HRC variants.
- Sustained Engine Efficiency — A correctly functioning rocker arm maintains proper valve timing so the engine delivers consistent power output during compaction passes; a worn or cracked rocker arm causes misfiring, valve float, and loss of compression.
- Genuine OEM Part — Backed by Wacker Neuson as a factory-authorized component, part number 5100031845 is the correct replacement as specified in the machine's service documentation.
The rocker arm is a critical component in the engine's valve train, acting as a lever that translates camshaft lobe movement into the opening and closing of intake and exhaust valves. On walk-behind tandem rollers like the RD7 and RD10 series, where the engine works under sustained load during asphalt and soil compaction, a worn or damaged rocker arm disrupts valve timing and can rapidly lead to rough running, loss of power, or internal engine damage. Replacing a faulty rocker arm promptly with a correctly specified part restores proper valve operation and protects the engine from further wear.
