The Wacker Neuson Compression Spring is a genuine OEM component designed for DPU80r, DPU90r, and DPU110r series reversible vibratory plate compactors. Sourced directly from Wacker Neuson, this is the same spring built into these machines at the factory, ensuring a direct, calibrated fit within the assembly. Confirmed fitment covers a wide range of DPU80r, DPU90r, and DPU110r models including Lec and Lem engine variants across multiple build series. When it's time to restore your compactor to full working order, the is the correct part for the job.
Key Features
- Genuine OEM Spring Rate — Manufactured to the exact load and deflection specification required by the DPU80r, DPU90r, and DPU110r assemblies, maintaining correct tension throughout the operating cycle.
- Drop-In Replacement — Matches the original mounting geometry and coil dimensions, allowing straightforward installation without modification to surrounding hardware.
- Broad DPU Series Fitment — Compatible with DPU80r Lec and Lem, DPU90r Lec and Lem, and DPU110r Lec and Lem variants, including US-market build series and KMAT configurations.
- Sustained Compaction Performance — A correctly tensioned compression spring maintains consistent force transfer within the vibration or control mechanism; a worn or broken spring can cause erratic plate behavior or loss of directional response.
- Verified OEM Part Number — Cross-reference 5100005921 against your machine's serial number and parts diagram before ordering to confirm the correct application.
A compression spring stores and releases mechanical energy to maintain tension, absorb shock, or keep components seated against a load within an assembly. In reversible vibratory plate compactors like the DPU series, compression springs are used in control linkages, exciter mechanisms, and vibration-damping mounts to ensure smooth, consistent plate movement and accurate directional control. When a compression spring fatigues, cracks, or loses its rated load capacity, the affected system can become sluggish, imprecise, or fail to return to its neutral position — directly impacting compaction quality and operator control.
