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, it is manufactured to the same specifications as the original, ensuring a correct fit within the assembly it serves. This washer is compatible across multiple serial number configurations of the RD27 family, making it a dependable choice whether you are performing scheduled maintenance or completing a repair. Confirming your machine's model and serial number against the fitment list before ordering is always recommended.
Key Features
- Genuine OEM Construction: — Sourced directly from Wacker Neuson, this washer meets the original dimensional and material tolerances specified for the RD27 roller platform — no guesswork on thickness, inner diameter, or hardness grade.
- Drop-In Fitment for RD27 Assemblies: — Engineered to seat correctly within the fastener stack or bearing interface it was designed for, eliminating the fit issues that come with non-specified substitutes.
- Broad RD27 Series Coverage: — Fits RD27-100 and RD27-120 hydrostatic vibratory rollers across standard and traction control variants, spanning a wide range of machine serial numbers.
- Protects Mating Components: — A correctly spec'd washer distributes load evenly across fastener joints and bearing faces, helping prevent premature wear, fretting, or fastener loosening under the constant vibration loads inherent to roller operation.
- Part Number Confidence: — OEM part number 5000161989 cross-references directly to the RD27 parts catalog, so you can order with confidence that you are receiving the correct part for your machine.
A washer serves as a load-distributing interface between a fastener — such as a bolt or nut — and the surface it clamps against. In vibration-intensive equipment like the RD27 hydrostatic vibratory roller, washers play a critical role in maintaining consistent clamping force by spreading the load over a wider bearing area and protecting softer mating surfaces from damage. When a washer becomes deformed, corroded, or lost during service, fastener joints can loosen prematurely or cause accelerated wear to the components around them, leading to more extensive repairs if not addressed promptly.
