The Wacker Neuson Tension Spring is a genuine OEM component designed for the BPU 3545A, BPU 4045A, BPU 5045A, and BPU 5545A series reversible vibratory plate compactors, including US-market variants. As a direct factory replacement, this part ensures your machine returns to proper operating specification without guesswork. It is compatible with both standard and US-model BPU configurations across the 35 kN, 40 kN, 45 kN, and 55 kN range.
Key Features
- Correct Spring Rate for BPU Applications — Manufactured to OEM tension tolerances, ensuring the spring delivers the precise load and return force required for BPU reversible plate operation.
- Drop-In Replacement — Matches the original mounting points and dimensions, allowing straightforward installation without modification to surrounding components.
- Broad BPU Series Coverage — Fits BPU 3545A, BPU 4045A, BPU 5045A, and BPU 5545A models, including US-market variants, covering a wide range of reversible vibratory plate compactors.
- Maintains Consistent Compaction Performance — A properly tensioned spring keeps internal mechanisms correctly loaded; a worn or broken spring can cause erratic plate behavior and uneven compaction output.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 5000125882 meets the same production standards as the original component installed at the factory.
A tension spring stores and releases mechanical energy to maintain consistent force or return a component to its resting position within the machine's operating cycle. In reversible vibratory plate compactors like the BPU series, tension springs play a role in controlling the behavior of moving assemblies, keeping parts properly seated and responsive under load. When a tension spring stretches beyond its rated length, loses elasticity, or breaks, it can cause misfiring of linked components, irregular machine response, and accelerated wear on adjoining parts — making timely replacement important to maintaining predictable compaction output.
