The Wacker Neuson Cylinder with Piston is a genuine OEM component designed for the RD7 series walk-behind tandem rollers and the DPU 4045H, DPU 5045H, and DPU 5545H series diesel reversible vibratory plate compactors. As a direct OEM part, the is manufactured to the exact tolerances and material specifications required by these machines, ensuring correct fitment and consistent performance under demanding compaction workloads. This assembly covers a wide range of RD7 variants — including the RD7H, RD7He, RD7Heh, RD7Hf, RD7Hehf, RD7Hfb, and RD7Hehfb — as well as the full DPU 4045H, DPU 4545H, DPU 5045H, and DPU 5545H model families. Sourcing a genuine Wacker Neuson cylinder with piston assembly means you get a bolt-in replacement that restores hydraulic or pneumatic integrity without rework or adaptation.
Key Features
- OEM-Matched Bore and Piston Tolerancing — Manufactured to the exact bore diameter and piston clearance specifications of the original assembly, maintaining proper compression and seal performance across the full operating cycle.
- Sold as a Complete Assembly — Cylinder and piston are supplied together as a matched unit, simplifying installation and eliminating the guesswork of sourcing components separately.
- Broad RD7 and DPU Series Coverage — Fits RD7H, RD7He, RD7Heh, RD7Hf, RD7Hfb, and related variants, plus the DPU 4045H, DPU 4545H, DPU 5045H, and DPU 5545H diesel plate compactor families.
- Restores Full Compaction Force Output — A worn or damaged cylinder and piston assembly directly reduces exciter or hydraulic output, leading to uneven compaction and failed lift compaction targets; this replacement restores the machine to its rated performance.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 5000226587 carries the same material grade and dimensional spec as the part it replaces, giving you full confidence in the repair.
The cylinder with piston assembly is a core mechanical component responsible for converting hydraulic or pneumatic pressure into linear force within the machine's exciter or drive system. On tandem rollers like the RD7 series, a correctly functioning cylinder assembly is essential for maintaining consistent drum force and smooth directional control. On DPU series reversible vibratory plates, this assembly plays a direct role in generating the compaction force delivered through the plate — when the cylinder or piston wears, scores, or seals fail, the machine loses compaction efficiency, may exhibit erratic vibration behavior, or can become difficult to control, making timely replacement critical to both output quality and operator safety.
