The Wacker Neuson Rocker Arm Complete is a genuine OEM Rocker Arm Complete designed for the DPU4045Yeh, DPU40Yeh, and DPU45Yeh series vibratory plates. Sourced directly from Wacker Neuson, this is the same assembly installed at the factory — no guesswork, no fitment concerns. Part number is confirmed across a broad range of DPU4045 and DPU40/45 Yeh-series models, including EU and US variants, as well as LRC-configured machines. When you need the correct part the first time, this OEM assembly delivers exactly that.
Key Features
- OEM-Spec Valve Train Geometry — Manufactured to Wacker Neuson's exact tolerances, ensuring correct rocker-to-valve contact and proper lift without adjustment.
- Drop-In Assembly — Supplied as a complete rocker arm assembly, so installation follows the original mounting configuration without additional fabrication or fitting.
- Broad DPU Series Coverage — Fits DPU4045Yeh, DPU4045Yehzf, DPU40Yeh, and DPU45Yeh models across US, EU, and LRC variants.
- Sustained Engine Efficiency — A correctly functioning rocker arm maintains proper valve timing and lift, keeping combustion efficient and engine output consistent under compaction loads.
- Genuine Wacker Neuson Part — Carries the full OEM part number 5100000731, so you can verify fitment with confidence against your machine's parts diagram.
The rocker arm is a critical component in the engine's valve train. It transfers motion from the camshaft — via the pushrod — to open and close the intake and exhaust valves at precisely the right moment. When a rocker arm wears, cracks, or loses its geometry, valve timing is disrupted, leading to rough running, loss of power, increased fuel consumption, and potential valve damage if left unaddressed. Replacing a worn rocker arm with a complete OEM assembly restores proper valve operation and protects the rest of the engine's top-end components.
