Wacker Neuson 5000086312 Ring Seal

The Wacker Neuson 5000086312 is a genuine OEM Ring Seal designed for the BS50-2, BS60-2, BS70-2, BS65-V, BS500, BS600, BS700, BS52Y, BS60Y, BS65Y, BS45YA, and MS52 and MS62 gasoline vibratory rammer series. This is a direct OEM replacement sourced through the Wacker Neuson parts program, meaning it meets the same specifications as the original component installed at the factory. With coverage spanning dozens of individual machine configurations — including "i" fuel-injected variants, EU-spec units, and "plus" models — part number 5000086312 is a high-volume service item across the BS rammer lineup. Confirming your machine number against the fitment list before ordering ensures a precise match.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to the same material grade and compression specification as the original ring seal, ensuring the sealing surface performs as designed under the dynamic loading conditions of a vibratory rammer.
• Drop-In Replacement — Installs directly into the same bore and seat as the original, with no machining or fitment adjustment needed to restore a proper seal.
• Broad BS Rammer Coverage — Fits an extensive range of Wacker Neuson BS-series rammers including BS50-2, BS50-2i, BS60-2, BS60-2i, BS70-2, BS70-2i, BS65-V, BS500, BS600, BS700, and legacy BS52Y, BS60Y, and BS65Y models, as well as MS52 and MS62 variants.
• Prevents Fluid Loss and Contamination — A worn or damaged ring seal allows oil or fuel to migrate where it should not, leading to performance loss, increased wear on surrounding components, and potential mechanical failure if left unaddressed.
• Fuel System Integrity — In fuel-related applications, a correctly seated ring seal is critical to preventing leaks and maintaining the safe operation of the rammer — particularly important on fuel-injected "i" series models where system pressure must be maintained.

A ring seal is a precision-formed sealing element that sits between mating components to prevent the passage of fluids or gases across a joint or bore. In a vibratory rammer like the Wacker Neuson BS series, ring seals are used at critical junctions within the fuel, oil, and internal mechanical systems to keep fluids contained and contamination out. When a ring seal degrades — through heat cycling, chemical exposure, or age — it loses its ability to maintain a proper barrier, which can result in leaks, pressure loss, or internal contamination that accelerates wear on nearby parts. Replacing a failed ring seal promptly with a correct OEM part restores the sealed system to proper working condition and protects the surrounding components.
