The Wacker Neuson is a genuine OEM Spring Washer designed for the RD27-100 and RD27-120 hydrostatic vibratory roller series. As a factory-sourced component, part is manufactured to the same specifications as the original hardware installed at the factory, ensuring a correct and consistent fit within the assembly. This Spring Washer is compatible across multiple configurations of the RD27 series, including standard and traction control variants. Keep this part on hand as a standard service item for any scheduled maintenance or fastener-related repair on your RD27 roller.
Key Features
- Genuine OEM Tension Rating — Sourced directly from Wacker Neuson, this Spring Washer delivers the correct load-bearing tension required to maintain secure fastener preload in roller assemblies.
- Direct Hardware Match — Matches the original part geometry and material grade, seating correctly against mating surfaces without shimming or adjustment.
- Broad RD27 Series Coverage — Fits RD27-100 and RD27-120 hydrostatic vibratory rollers across standard and traction control configurations, covering a wide range of machine numbers within the RD27 family.
- Fastener Integrity — A correctly functioning Spring Washer maintains constant clamping force against vibration; a worn or flattened washer allows fasteners to back out, leading to component loosening and potential mechanical failure.
- Part Number Confidence — Order by part number 5000161550 to ensure you receive the exact washer specified for your machine — not a generic substitute.
A Spring Washer is a hardened, curved or coiled fastener component that sits beneath a bolt head or nut to apply continuous spring tension against the joint. In high-vibration equipment such as tandem vibratory rollers, fasteners are constantly subjected to dynamic loading that can cause them to loosen over time. The Spring Washer resists this loosening by maintaining axial preload force even as the joint experiences repeated stress cycles. When a Spring Washer becomes flattened, cracked, or corroded, it loses its ability to hold that tension, which can result in loose hardware, misaligned components, or accelerated wear elsewhere in the assembly.
