The Wacker Neuson Leg Spring is a genuine OEM leg spring designed for the DPU6555, DPU5545, DPU4545, and RD7H series reversible plate compactors. As a direct OEM component, it is manufactured to the same specification as the original part fitted at the factory, ensuring consistent performance across the full range of compatible machines. This part covers a broad spread of DPU and RD7H variants, so verify your model number against the fitment list before ordering.
Key Features
- OEM Spring Temper and Geometry — Manufactured to the exact coil dimensions and spring rate of the original, so tension and travel characteristics match what the machine was engineered around.
- Direct Drop-In Replacement — Seats into the existing leg mounting points without rework, keeping installation straightforward for technicians already familiar with the platform.
- Broad DPU and RD7H Coverage — A single part number covers DPU6555, DPU5545, DPU4545, and RD7H series machines, including He, Heh, Hech, Heap, Hes, and Hesh variants.
- Sustained Vibration Isolation — A correctly tensioned leg spring absorbs and dampens compaction forces through the exciter assembly, protecting the frame and operator from excessive shock loading.
- Backed by Wacker Neuson's OEM Parts Program — Supplied as a genuine Wacker Neuson part, carrying the same part number — 5100051934 — used in official service documentation.
The leg spring on a reversible plate compactor is part of the vibration isolation system that connects the exciter housing to the machine's base frame or handle assembly. It absorbs the high-frequency compaction forces generated by the exciter, preventing those forces from transmitting fully into the frame and operator controls. When a leg spring fatigues, cracks, or loses its rated tension, the machine can develop excessive vibration at the handles, uneven compaction behavior, and accelerated wear on surrounding components — making timely replacement important for both output quality and operator comfort.
