The Wacker Neuson Spring is a genuine OEM component designed for DS70 and DS720 diesel vibratory rammers, as well as select DPU, VPY, and VP series vibratory plates. Sourced directly from Wacker Neuson, this spring meets the exact specifications required for proper machine operation across a wide range of compaction equipment. Fitment covers multiple DS70 and DS720 configurations including 280mm and 330mm shoe variants, along with DPS1850Y, DPU 2950Y, VPY1740, VPY1750, and VP2050Y vibratory plates. Having the correct OEM part on hand keeps your compaction equipment running to specification without guesswork.
Key Features
- Genuine OEM Spring Tension Integrity — Manufactured to Wacker Neuson's exact load and deflection specifications, ensuring the spring delivers consistent force without premature fatigue or set.
- Direct Drop-In Replacement — Engineered to seat and secure exactly as the original, with no reworking of mating components required during installation.
- Broad Compaction Equipment Fitment — Compatible with DS70 and DS720 diesel rammers across multiple shoe sizes, plus DPS1850Y, DPU 2950Y, VPY1740, VPY1750, and VP2050Y vibratory plate models.
- Sustained Compaction Output — A correctly tensioned spring maintains the mechanical cycling needed for consistent impact force; a worn or broken spring can cause erratic compaction strokes or machine shutdown.
- OEM Part Number Confidence — Part number 5000073781 is verified against Wacker Neuson's parts catalog, so you can order with confidence that this is the correct component for your machine.
A spring in a diesel rammer or vibratory plate plays a critical role in the machine's reciprocating or vibration mechanism, storing and releasing energy to maintain consistent stroke or oscillation cycles. In a rammer like the DS70 or DS720, the spring works in coordination with the engine's crankshaft to drive the ramming shoe downward with controlled force — if it loses tension, weakens, or breaks, the machine's compaction output drops off or becomes uneven. In vibratory plate applications, springs contribute to isolating the operating handle from vibration or assist in maintaining component preload, and a failed spring can accelerate wear on surrounding parts or affect operator comfort and machine balance.
