Wacker Neuson 5000104429 Fixing Disc

The Wacker Neuson is a genuine OEM Fixing Disc designed for the RD7H series walk-behind tandem rollers and a wide range of DPU reversible vibratory plate compactors, including the DPU 4045H, DPU 5045H, DPU 4545H, and DPU 5545H series. As a factory-sourced component, part meets the original design tolerances Wacker Neuson specifies for these machines, ensuring proper retention and alignment exactly as built. This Fixing Disc fits an extensive spread of RD7H configurations — including standard, electric-start, and foldable-handle variants — as well as multiple DPU model generations sold across North American and European markets. When sourcing a replacement, confirming part number against your machine's serial number plate is always recommended given the breadth of compatible configurations.

Key Features

• Genuine OEM Retention Integrity — Factory-sourced from Wacker Neuson, this disc meets the original clamping and dimensional tolerances required to hold components securely under continuous vibration loads.
• Direct Drop-In Replacement — Engineered to the same bolt pattern and disc profile as the original, allowing straightforward installation without reworking mounting hardware.
• Broad Cross-Series Fitment — Compatible with RD7H tandem rollers (including RD7He, RD7Heh, RD7Hf, and RD7Hfb variants) and DPU 4045H, DPU 5045H, DPU 4545H, and DPU 5545H reversible vibratory plate compactors across multiple production runs.
• Vibration-Resistant Fastening — A correctly seated fixing disc prevents component loosening and misalignment that high-frequency compaction cycles would otherwise accelerate, protecting surrounding hardware from premature wear.
• Multi-Market Coverage — Fits both standard and US-market model variants, making this a single verified part for fleets operating across different regional configurations.

A fixing disc is a retention component that secures a rotating or mounted assembly in its correct axial position, preventing lateral movement and maintaining concentricity under load. On vibratory compaction equipment — whether a tandem roller or a reversible plate compactor — the machine generates sustained, high-amplitude vibration that places constant stress on fastening hardware. If the fixing disc wears, cracks, or is improperly seated, the component it retains can shift out of alignment, leading to accelerated wear on adjacent parts, increased vibration transmitted to the machine frame, and potential operational failure. Replacing a worn fixing disc promptly with the correct OEM part keeps the retained assembly running true and protects the integrity of the broader drivetrain or exciter system it supports.
