The Wacker Neuson Cylinder with Piston is a genuine OEM assembly designed for the DPU 6055 series reversible vibratory plate compactors. As a direct factory-sourced component, it meets the exact tolerances and material specifications Wacker Neuson engineers to for the DPU 6055 platform — including the standard, H, He, and Heap variants. If your DPU 6055 is losing compression, burning oil, or failing to develop full compaction force, this is the core internal engine assembly you need to restore it to working condition. Confirm your machine number against the DPU 6055 fitment list to ensure this is the correct assembly for your unit.
Key Features
- OEM Compression Integrity — Manufactured to Wacker Neuson's original bore diameter and piston-to-wall clearance specs, ensuring the engine rebuilds to its rated compression ratio rather than an approximation.
- Complete Cylinder and Piston Assembly — Supplied as a matched set, so the bore surface and piston crown geometry are dimensionally paired from the factory — no mismatched components to work around.
- DPU 6055 Series Fitment — Verified for DPU 6055 reversible vibratory plate compactors across multiple machine configurations, including standard, H, He, and Heap variants operating at 60 kN compaction force with a 55 cm / 22 in drum width.
- Restores Full Compaction Output — A worn or scored cylinder causes power loss and uneven compaction force. Replacing with a correctly spec'd OEM assembly brings the plate back to its rated 60 kN output, maintaining pass counts and compaction depth on cohesive soils and aggregate bases.
- Fuel and Emission System Compliance — An OEM-matched cylinder and piston maintains the correct combustion chamber volume, which is critical for keeping fuel consumption and exhaust emissions within the machine's original certified parameters.
The cylinder and piston are the heart of the engine's power stroke. The cylinder provides the sealed bore in which combustion gases expand, and the piston converts that pressure into the crankshaft rotation that drives the exciter unit — ultimately generating the vibratory force that compacts the soil beneath the plate. When the cylinder bore wears, scores, or the piston rings lose their seal, compression drops, the engine runs poorly, and compaction output falls off noticeably. Replacing this assembly as a matched unit restores the full combustion seal, brings power output back up to spec, and protects the crankshaft and bearings from the added stress that comes with a low-compression engine working harder than it should.
