The Wacker Neuson 5000078849 is a genuine OEM O-Ring Segment designed for the BS-series vibratory rammers, including the BS45Y, BS50-2i, BS52Y, BS60Y, and BS65Y models. As a genuine Wacker Neuson part, the 5000078849 is manufactured to the exact material grade and dimensional tolerances required for a secure, leak-free seal in these machines. Compatibility spans multiple production runs and serial number ranges across the BS rammer family, making this a widely applicable service part. Always confirm your machine's model and serial number against the fitment list before ordering.
Key Features
- Correct Elastomer Specification — manufactured to the precise compound and cross-section profile required for the BS-series rammer's sealing environment, ensuring consistent compression and no fluid bypass.
- Genuine OEM Sourcing — supplied directly through the Wacker Neuson parts network, meaning this is the same O-Ring Segment installed at the factory.
- Broad BS-Series Compatibility — fits multiple variants of the BS45Y, BS50-2i, BS52Y, BS60Y, and BS65Y vibratory rammers across a wide range of production serial numbers.
- Drop-In Replacement — matches the original groove geometry and seating dimensions exactly, so the ring seats correctly without stretching or reshaping during installation.
- Protects Internal Components — a properly seated O-Ring Segment prevents oil or fluid migration between sealed chambers, keeping the rammer's internal assemblies clean and properly lubricated.
An O-Ring Segment serves as a precision sealing element between mating surfaces or housing sections within the rammer. It prevents fluid or lubricant from migrating between chambers, maintaining the correct pressure and lubrication conditions inside the machine. When an O-Ring Segment deteriorates, cracks, or loses its compression set, leaks develop that can lead to lubricant loss, contamination of adjacent assemblies, and accelerated wear on internal components — making timely replacement critical to keeping the rammer running correctly.
