The Wacker Neuson O-Ring 1.171 X.116 Dur90 3-916 is a genuine OEM sealing component designed for the RT560, RT820, RT820HT, and CRT60-66K series machines. Sourced directly from Wacker Neuson, this part carries the same material grade and dimensional tolerances as the original, ensuring a correct, leak-free seat every time it is installed. It is confirmed to fit multiple machine numbers across the RT560, RT820, RT820HT vibratory trench roller family and the CRT60-66K ride-on concrete trowel series.
Key Features
- Durometer-Rated Sealing Material — Rated at 90 Shore A durometer hardness, this O-ring delivers the compression resistance and resilience needed to maintain a consistent hydraulic or fluid seal under operating pressure.
- Exact Dimensional Match — At 1.171 in. inner diameter and .116 in. cross-section, this genuine OEM part installs directly into the original groove seat without trimming, shimming, or modification.
- Broad Fitment Across RT and CRT Series — Compatible with the RT560, RT820, and RT820HT vibratory trench rollers and the CRT60-66K ride-on concrete trowel, covering a wide range of machine configurations and serial number ranges.
- Leak Prevention Keeps Hydraulics Performing — A correctly seated O-ring maintains system pressure in hydraulic and fluid circuits, preventing seepage that can lead to component wear or unplanned fluid loss during operation.
- Genuine OEM Part Integrity — As an authentic Wacker Neuson component, part number 5000080735 is manufactured to the same specification as the original, giving you confidence in material quality and service life.
An O-ring is a precision-molded loop of elastomeric material that sits in a machined groove to create a static or dynamic seal between two mating surfaces, preventing fluid or hydraulic oil from escaping under pressure. In trench rollers and ride-on trowels, O-rings are found throughout hydraulic circuits, motor housings, and fluid connections where maintaining seal integrity is critical to consistent machine operation. When an O-ring hardens, cracks, or becomes deformed from age or heat cycling, it loses its ability to hold pressure, resulting in fluid leaks that can compromise hydraulic response and accelerate downstream component wear.
