The Wacker Neuson Washer is a genuine OEM component designed for the RD27-100 and RD27-120 series hydrostatic vibratory rollers, including standard and traction control configurations. As a factory-sourced part, the is manufactured to the exact tolerances specified for these machines, ensuring proper load distribution and secure fastener seating at the point of installation. This washer is confirmed to fit across the full range of RD27-100 and RD27-120 variants covered under this part number, making it a straightforward service replacement when inspecting or reassembling fastened joints on your roller.
Key Features
- Exact OEM Geometry — Manufactured to the precise outer diameter, inner bore, and thickness specified for RD27-series roller assemblies, ensuring correct load distribution across the mating surface.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, this washer carries the same material grade and dimensional spec as the original installed at the factory.
- Broad RD27 Series Coverage — Fits RD27-100 and RD27-120 hydrostatic vibratory rollers in both standard and traction control configurations across multiple machine numbers.
- Protects Fastener Integrity — A properly sized washer prevents fastener pull-through and surface damage at critical joint locations; an undersized or worn washer can lead to loosening under vibration loads typical of roller operation.
- Drop-In Service Replacement — Installs directly in place of the original without rework, supporting efficient maintenance turnaround during scheduled service or field repairs.
A washer serves as a load-distributing interface between a fastener — such as a bolt or nut — and the surface it clamps against. By spreading the clamping force over a wider area, it prevents the fastener from biting into or pulling through the mating material, which is especially important on equipment subject to sustained vibration like a tandem vibratory roller. When a washer deforms, corrodes, or goes missing, the fastener joint can lose clamping tension over time, potentially allowing components to shift or work loose during operation. Replacing a worn or damaged washer with the correct OEM piece restores the joint to its intended clamping specification.
