Wacker Neuson 1000225658 Seal Kit Gear Pump

The Wacker Neuson Seal Kit Gear Pump is a genuine OEM seal kit designed for the WL50 Articulated Wheel Loader. As a direct Wacker Neuson OEM part, the delivers the exact material grades and dimensional tolerances required to restore proper hydraulic gear pump sealing on the WL50. This kit covers the seals needed to bring a leaking or worn gear pump back to full operating condition, helping you keep the WL50's hydraulic system running at the pressures it was built for.

Key Features

• OEM Seal Material Grade — Genuine Wacker Neuson seals are manufactured to the exact compound and hardness specifications of the original gear pump seals, ensuring correct compression and long-term integrity under hydraulic pressure.
• Complete Kit for Gear Pump Rebuild — Includes all seals required for a full gear pump reseal, so you have everything on hand before teardown begins.
• Direct Fit for WL50 — Engineered specifically for the WL50 Articulated Wheel Loader (Cab), confirming correct sizing and seal profile without modification.
• Restores Hydraulic System Pressure — Worn or damaged gear pump seals cause internal bypass, pressure loss, and sluggish loader or hydraulic attachment response. A fresh seal kit brings pump output back to spec.
• Fuel and Fluid Compatibility — OEM seals are formulated to resist hydraulic fluid degradation, maintaining their sealing properties over extended service intervals in demanding loader applications.

The gear pump seal kit contains the internal sealing elements that prevent hydraulic fluid from bypassing or leaking past the rotating gears inside the pump. When these seals are in good condition, the pump maintains the flow and pressure the WL50's hydraulic circuits depend on for lifting, steering, and attachment operation. As seals age or are exposed to contaminated fluid, they harden, crack, or deform — leading to internal leakage, reduced hydraulic power, and potential pump failure if left unaddressed. Replacing the seals with a genuine OEM kit like the 1000225658 restores pump efficiency and protects the broader hydraulic system from the wear caused by low-pressure operation.
