The Wacker Neuson is a genuine OEM Shaft Seal designed for a range of Wacker Neuson equipment including PTS4V centrifugal trash pumps, GPS9700 and GPS8500 portable generators, GS8.5V and GS9.7V portable generators, and RD11V and RD880V double drum vibratory rollers. Sourced directly from Wacker Neuson, this seal is manufactured to the exact material and dimensional tolerances of the original component. It installs as a direct replacement with no modification to the housing or shaft required, making it a straightforward service part for scheduled maintenance or unplanned repairs. Confirm your model and machine number against the fitment list before ordering to ensure is the correct seal for your application.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's original lip-seal specifications, ensuring correct compression against the rotating shaft and sustained leak-free operation.
- Direct Housing and Shaft Fit — Engineered to the exact bore diameter and shaft diameter of the original application, seating squarely into the housing bore without machining or shimming.
- Wide Fitment Coverage — Verified for PTS4V trash pump variants, GPS8500 and GPS9700 portable generator families, GS8.5V and GS9.7V generators, and RD11V and RD880V double drum vibratory rollers.
- Prevents Fluid Loss and Contamination — A correctly seated shaft seal keeps lubricating oil or pump fluid contained while blocking dirt and moisture ingress — a worn seal leads to lubricant loss, overheating, and accelerated bearing wear.
- Genuine OEM Traceability — Supplied under Wacker Neuson part number 5000081018, giving you confidence that the part matches the original engineering specification for each listed machine.
A shaft seal sits at the point where a rotating shaft exits a housing — such as a pump casing, gearbox, or crankcase — and its job is to create a dynamic barrier between the inside and outside of that housing. On trash pumps like the PTS4V, it prevents water and abrasive slurry from migrating into the bearing cavity while keeping lubricant from escaping into the pump volute. On generators and rollers, it retains oil around the rotating shaft interface and stops external contamination from entering critical running surfaces. When a shaft seal wears or hardens with age, the first signs are weeping oil around the shaft exit or water in the oil — left unaddressed, bearing failure and major component damage typically follow.
