Wacker Neuson 5002004455 Shaft Seal 55 X 70 X 8, 1B

The Wacker Neuson Shaft Seal 55 X 70 X 8, 1B is a genuine OEM component designed for the BS65-V, BS650, and BS65Y series variable speed vibratory rammers. Sourced directly from Wacker Neuson, this seal carries the same material grade and dimensional tolerances as the original part installed at the factory. It fits across multiple configurations within the BS65 rammer family, including 280mm/11in shoe variants, making it the straightforward choice for scheduled maintenance or field repair. Confirm your model number before ordering to ensure a correct match.

Key Features

• OEM-Grade Seal Integrity — Manufactured to Wacker Neuson's original compression and material specifications, delivering the same sealing performance as the part your machine shipped with.
• Correct Dimensional Fit — The 55 x 70 x 8mm profile seats directly into the original bore without modification, ensuring proper lip contact and shaft alignment on installation.
• Broad BS65 Series Coverage — Compatible with BS65-V, BS650, and BS65Y variable speed rammers equipped with the 280mm/11in shoe, covering a wide range of production configurations within this rammer family.
• Protects Drive Components — A properly functioning shaft seal keeps lubricant where it belongs and blocks contaminants from entering the drivetrain; a worn seal allows oil loss and ingress that accelerates internal wear.
• Genuine Wacker Neuson Part — Supplied as an authentic OEM replacement, so you can be confident in traceability and consistency when servicing rammers on active job sites.

A shaft seal creates a dynamic barrier between a rotating shaft and the surrounding housing, retaining internal lubrication while preventing dirt, moisture, and debris from entering the assembly. In a vibratory rammer, where the drive mechanism operates under repeated high-impact loading, maintaining this seal is critical — lubricant film on the shaft surfaces directly affects how smoothly internal components move and how long they last. When a shaft seal begins to leak or fail, oil escapes the housing, the shaft runs dry, and bearing and gear wear accelerates rapidly, often leading to more extensive and costly drivetrain damage if left unaddressed.
