The Wacker Neuson Tension Spring is a genuine OEM tension spring designed for DPU 2540H, DPU 2550H, DPU 2560H, DPU 2560H-TS, and BPU 2540A series vibratory plates. Sourced directly from Wacker Neuson, this part meets the exact material and load specifications of the original component installed at the factory. It is a confirmed fit for all models listed above, including BPU 2540A US and BPU 2540A CN variants, so you can order with confidence that is the correct part for your machine.
Key Features
- Correct Spring Rate for Vibratory Plate Applications — Manufactured to the original load and extension specification, ensuring the spring delivers the tension the system was engineered around, not an approximation.
- Drop-In OEM Replacement — Matches the original mounting points and hook geometry of the factory part, so installation goes straight in without reworking brackets or anchor points.
- Broad DPU and BPU Series Coverage — Fits DPU 2540H, DPU 2550H, DPU 2560H, DPU 2560H-TS, BPU 2540A, BPU 2540A US, and BPU 2540A CN vibratory plates under a single part number.
- Sustained Compaction Output — A properly tensioned spring keeps the exciter and related drive components operating in their correct range; a worn or broken spring leads to inconsistent vibration, reduced compaction force, and accelerated wear on surrounding parts.
- Genuine Wacker Neuson Quality — As an authentic OEM part, 5100031125 is produced to the same steel grade and heat treatment as the component it replaces, giving it the service life expected by the original design.
A tension spring in a vibratory plate compactor applies a constant pulling force to hold a mechanism — such as a throttle linkage, belt tensioner, or exciter housing component — in its correct operating position. When the spring is at the right tension, the machine responds predictably and components stay properly loaded during operation. As the spring stretches, weakens, or breaks, that controlled force disappears: linkages become sloppy, belts lose contact, or moving parts shift out of alignment, which quickly causes erratic performance and secondary damage to connected components. Replacing a fatigued or failed tension spring promptly is one of the lower-cost interventions that prevents a straightforward maintenance task from turning into a more significant repair.
