The Wacker Neuson 5200021779 is a genuine OEM Bushing designed for the APT6S and APT6T series self-priming pumps. Sourced directly from Wacker Neuson, this replacement Bushing delivers the exact dimensional tolerances required to maintain proper shaft alignment and bearing support within these pump assemblies. Confirmed fitment spans the full APT6S and APT6T lineup, including Surge Brake, Electric Brake, and Cold Weather variants. Keeping this component in good working order is essential to preventing premature wear on surrounding pump components and maintaining consistent pumping performance on the jobsite.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Wacker Neuson's original bore and outer diameter specifications, ensuring the Bushing seats correctly without play or misalignment in the pump housing.
- Drop-In Replacement — Matches the original mounting geometry of the APT6S and APT6T pump assemblies, allowing straightforward installation without modification to adjacent components.
- Broad APT6 Series Compatibility — Fits APT6S Pump w/Skid, APT6T Pump with Surge Brake, APT6T Pump with Electric Brake, and all corresponding Cold Weather variants.
- Protects Shaft and Housing Integrity — A correctly fitted Bushing absorbs radial load and reduces metal-on-metal contact; a worn Bushing accelerates shaft scoring and can cause pump seizure.
- Verified Part Number — Order with confidence using Wacker Neuson part number 5200021779, cross-referenced to the full APT6 pump product family.
A bushing is a cylindrical sleeve fitted between a rotating shaft and its surrounding housing or bearing bore. In a pump assembly, it provides a low-friction bearing surface that supports the shaft under radial load and keeps it running true during operation. When a bushing wears out or fails, the shaft begins to run off-center, which increases vibration, accelerates seal wear, and can ultimately cause the pump to lose prime or suffer internal damage — making timely replacement critical to keeping the unit in service.
