The Wacker Neuson is a genuine OEM O-Ring 2.5 X 1.7 designed for the BS-series vibratory rammer lineup, covering a wide range of models including the BS50-2, BS50-2i, BS60-2, BS60-2i, BS70-2, BS70-2i, BS500, BS600, BS700, BS52Y, BS60Y, BS45Y, BS65-V, and BS650 rammers. As a direct OEM replacement sourced through authorized Wacker Neuson supply channels, part number meets the same material and dimensional standards as the original component installed at the factory. This O-ring serves critical sealing duties within the rammer, and using the correct-specification part helps maintain fluid integrity and consistent machine performance. With fitment spanning standard, oil-injected, variable-speed, and high-altitude rammer configurations across multiple generations, this is a high-demand service part worth keeping on hand.
Key Features
- Correct Durometer and Dimensional Spec — Manufactured to the precise 2.5 x 1.7 cross-section required for a proper seal seat in Wacker Neuson BS-series rammer assemblies.
- Genuine OEM Part — Supplied as an authentic Wacker Neuson component under part number 5000074544, ensuring material composition matches the original seal specification.
- Broad BS-Series Compatibility — Fits a wide range of BS vibratory rammers including BS50-2, BS60-2, BS70-2, BS500, BS600, BS700, BS52Y, BS60Y, BS45Y, BS65-V, and oil-injected and high-altitude variants.
- Maintains Fluid Seal Integrity — A correctly seated O-ring prevents oil or fuel seepage that can lead to contamination, power loss, or accelerated internal wear in the rammer engine and drive system.
- Covers Multiple Configuration Types — Compatible with standard vibratory, oil-injected, variable-speed, and high-altitude rammer builds, making it a versatile stock item for service technicians maintaining mixed BS-series fleets.
An O-ring is a precision-molded elastomeric seal used at joints, ports, and mating surfaces throughout a rammer's engine and drive assembly to prevent the passage of fluids or gases between components. In a vibratory rammer like the Wacker Neuson BS-series, these seals are critical at fuel system connections and internal lubrication points, where even a minor leak can compromise engine performance or cause oil contamination. When an O-ring hardens, cracks, or deforms from heat and age, it loses its ability to maintain a consistent seal — resulting in weeping joints, loss of oil pressure, or fuel odors that signal it is time for replacement.
