The Wacker Neuson Compression Spring is a genuine OEM component designed for the DPU6555, DPU5545, DPU4545, DPU4045, BPU5545A, and BPU4045A series reversible and forward plate compactors. As a factory-sourced part, the is manufactured to the same specifications as the original, ensuring a direct, drop-in fit with no guesswork at installation. This spring is built to maintain consistent tension and load characteristics across the full operating range of your compactor. With broad fitment coverage spanning multiple DPU and BPU series machines — including US, AP, HE, HEC, HEH, and ZF variants — this single part number serves as the correct replacement across a wide range of Wacker Neuson plate compactor configurations.
Key Features
- Genuine OEM Spring Tension Rating — Manufactured to match the original load and compression specs, so the spring delivers the correct force without over- or under-compressing in service.
- Direct-Fit Replacement — Engineered to seat and secure exactly as the original, maintaining proper alignment within the compactor's exciter or control mechanism assembly.
- Wide Series Fitment — Compatible with DPU6555, DPU5545, DPU4545, DPU4045, BPU5545A, and BPU4045A series machines, including HE, HEH, HEC, AP, US, and ZF variants.
- Consistent Compaction Force Maintained — A properly functioning compression spring keeps mechanical components seated under load, supporting steady vibration output and even compaction performance.
- Genuine Wacker Neuson Part — Sourced directly through the Wacker Neuson OEM supply chain, so fitment, material grade, and spring geometry are verified against the original equipment design.
A compression spring in a plate compactor serves as a mechanical tensioning element — holding components under a set load, absorbing shock between moving parts, or maintaining consistent contact pressure within an assembly. When a compression spring weakens, loses its set, or breaks, the affected mechanism can shift out of position, resulting in inconsistent compaction force, unusual vibration behavior, or premature wear on surrounding components. Replacing a fatigued or broken spring promptly with the correct OEM part restores proper mechanical function and prevents secondary damage to adjacent parts in the assembly.
