The Wacker Neuson 5100031819 is a genuine OEM Crankshaft Complete designed for the RD7Ye and RD10Yehf LRC series walk-behind tandem rollers. Sourced directly through Wacker Neuson's authorized parts program, this crankshaft assembly meets the exact tolerances and material specifications of the original component. It is confirmed to fit multiple RD7Ye configurations, including the RD7Yeh LRC, RD7Yehf LRC, and RD7Yehfb LRC variants, as well as the RD10Yehf LRC. Replacing a worn or damaged crankshaft with the correct OEM unit ensures the engine returns to proper operating condition without the guesswork of cross-referencing aftermarket alternatives.
Key Features
- OEM-Matched Crankshaft Geometry — Manufactured to the same journal dimensions, stroke length, and bearing seat tolerances as the original, ensuring correct reciprocating balance within the engine assembly.
- Drop-In Engine Compatibility — Engineered to install directly into the existing engine block, aligning with the original bearing housings, seals, and connecting rod without modification.
- Broad RD7Ye and RD10 Series Coverage — Fits RD7Ye, RD7Yeh LRC, RD7Yehf LRC, RD7Yehfb LRC, and RD10Yehf LRC walk-behind tandem rollers across multiple machine configurations.
- Restored Engine Power Output — A failed or scored crankshaft causes loss of compression, excessive vibration, and engine knock; a correct replacement restores full power delivery to the drum drive system.
- Genuine Wacker Neuson Part — Supplied as a complete crankshaft assembly under part number 5100031819, backed by Wacker Neuson's OEM parts program for traceability and quality assurance.
The crankshaft is the central rotating component of the engine, converting the up-and-down motion of the pistons into the rotational force that drives the machine. In a walk-behind tandem roller like the RD7Ye or RD10Yehf LRC, a properly functioning crankshaft is essential for smooth engine operation and consistent power delivery to the exciter and propulsion systems. When the crankshaft wears, cracks, or suffers journal damage — often from oil starvation or bearing failure — the engine will produce knocking, vibration, or loss of power, and continued operation risks catastrophic engine damage.
