The Wacker Neuson is a genuine OEM Exhaust Rocker Arm designed for DPU and DPS series vibratory plate compactors and the RS800H single drum vibratory roller. Sourced directly through Wacker Neuson's authorized parts chain, this component matches the original specification installed at the factory. Compatible models include the DPU 2870, DPU 2950, DPU 2960, DPU 2970, DPS 3050, DPS 3060, and RS800H. If your engine is showing signs of valve train wear — loss of compression, rough idle, or uneven power delivery — the is the correct OEM replacement to restore proper valve actuation.
Key Features
- OEM Valve Train Geometry — Manufactured to the exact pivot radius and arm profile required for correct valve lift and timing on Wacker Neuson engines in this series.
- Drop-In Rocker Shaft Replacement — Mounts directly onto the rocker shaft with no re-drilling or machining; designed to align with the existing valve stem and pushrod contact points.
- Broad Compaction Family Coverage — Fits DPU 2870, DPU 2950, DPU 2960, DPU 2970, DPS 3050, DPS 3060, and RS800H — covering reversible and single-direction plate compactors alongside the RS800H roller.
- Restores Full Engine Compression — A worn or cracked exhaust rocker arm causes incomplete valve closure, leading to compression loss, hard starting, and reduced compaction force; replacing it brings the engine back to full output.
- Genuine OEM Part — Carries Wacker Neuson OEM part number 5004101511, ensuring you receive the correct part the first time with no compatibility guesswork.
The exhaust rocker arm is a critical component of the engine's valve train, sitting between the camshaft-driven pushrod and the exhaust valve stem. As the camshaft rotates, the pushrod lifts one end of the rocker arm, which pivots on its shaft and presses the exhaust valve open — allowing combustion gases to exit the cylinder. When the rocker arm wears at its contact faces, cracks, or loses its correct pivot geometry, the exhaust valve cannot open or close fully, resulting in lost compression, excessive exhaust smoke, rough running, and reduced engine power. On compaction equipment like the DPU and DPS series plates, where consistent engine output directly drives vibration force and compaction performance, a failed rocker arm can render the machine ineffective on the jobsite.
