The Wacker Neuson Spring Washer is a genuine OEM Spring Washer designed for the RC50, RC50P, RC70, RC70P, and RC70VO single drum soil compactor series. As a factory-sourced component, this part is manufactured to the exact specifications used in original production, ensuring a direct, drop-in replacement for the worn or damaged washer in your machine. Fitment covers both standard and US-market variants across the RC50 and RC70 families, making the correct choice for a wide range of Wacker Neuson compactor configurations.
Key Features
- Correct Spring Tension Rating — Sourced directly from Wacker Neuson, this genuine OEM Spring Washer delivers the precise load-bearing and spring characteristics the fastener assembly requires — no substitution, no compromise.
- Direct Bolt-In Replacement — Matches the original washer's diameter, thickness, and seating profile for a clean installation without machining or shimming.
- Broad RC50 & RC70 Series Coverage — Compatible with RC50, RC50P, RC70, RC70P, and RC70VO compactors, including US-market models, across multiple production series.
- Maintains Clamping Force Under Vibration — In a high-cycle, high-vibration machine like a soil compactor, a spring washer is critical to keeping fasteners torqued and secure; a fatigued or missing washer leads to fastener loosening and accelerated mechanical wear.
- Genuine OEM Traceability — Part number 5100022881 is an active Wacker Neuson part, cross-referenced against current factory parts documentation for verified accuracy.
A spring washer is a small but mechanically important component used beneath a bolt or nut to maintain clamping load in assemblies subject to vibration and dynamic loading. On a single drum soil compactor — where the drum generates continuous vibration through the machine frame — spring washers prevent fasteners from backing out over time, protecting the integrity of critical joint connections. When a spring washer loses its temper or becomes flattened from over-torquing or age, it can no longer maintain the required preload, leading to loose hardware, misalignment, and potential component damage if left unaddressed.
