Oil Shaft Seal | GX160, GX200 | 25x41x6B

The Wacker Neuson Shaft Seal is a genuine OEM component designed for a wide range of Wacker Neuson equipment, including BFS735 floor saws, CT36-5A and CT30 walk-behind concrete trowels, PT2A trash pumps, GP2500A and GV2500A portable generators, WP and VP series single-direction vibratory plate compactors, BPU reversible vibratory plate compactors, and BPS series vibratory plates. As a genuine OEM part, the is manufactured to the exact specifications of the original seal, ensuring a proper fit and consistent sealing performance across every compatible machine. This shaft seal is a high-demand service item that spans multiple Wacker Neuson product families, making it a practical stock item for fleet operators and service technicians. Always verify your model and machine number before ordering to confirm compatibility.

Key Features

• Exact OEM Sealing Specification — Manufactured to the original lip geometry and material grade, maintaining proper shaft-to-housing sealing integrity under both static and dynamic conditions.
• Drop-In Replacement Across Multiple Machine Families — Fits directly into the original seal bore with no rework required, covering floor saws, concrete trowels, trash pumps, generators, and vibratory plate compactors.
• Broad Fitment Coverage — Compatible with BFS735 floor saws, CT30 and CT36 walk-behind trowels, PT2A trash pumps, GP/GV generators, WP/VP/BPU/BPS vibratory plate compactors, and select internal vibrator power units.
• Protects Internal Components From Contamination — A properly seated shaft seal prevents oil, grease, or fluid loss and blocks dust, water, and debris from entering the housing — both of which accelerate bearing and gear wear when the seal fails.
• Genuine OEM Quality Assurance — Sourced directly through Wacker Neuson's parts supply chain, this seal meets the same dimensional tolerances and elastomer compound specifications as the part originally installed at the factory.

A shaft seal is a precision ring fitted around a rotating shaft where it passes through a housing, gearcase, or pump body. Its job is twofold: it retains lubricating oil or grease inside the housing while simultaneously blocking external contaminants — dirt, water, and debris — from reaching the bearings and internal gears. When a shaft seal wears, cracks, or hardens with age, you'll typically see oil weeping around the shaft exit point, which leads to lubricant starvation in the housing and accelerated wear on bearings and rotating components. On equipment like trash pumps and concrete trowels, a failed shaft seal can also allow water or slurry to migrate inward, causing corrosion damage that far exceeds the cost of the seal itself. Replacing the seal at the first sign of leakage is the most cost-effective way to protect the drivetrain of any machine in this product family.
