The Wacker Neuson 5200021730 is a genuine OEM Bearing Housing designed for the APT6T and APT6S series self-priming trash pumps. As a direct OEM replacement sourced from Wacker Neuson, this component is manufactured to the same specifications as the original part installed at the factory. Fitment covers the full APT6T and APT6S lineup, including Surge Brake, Electric Brake, Cold Weather, and Skid-mounted configurations. When your pump's bearing housing shows wear, scoring, or damage, replacing it with the correct OEM part restores proper shaft alignment and protects the internal rotating assembly.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original material and dimensional specifications, ensuring the housing bore maintains correct tolerancing for the pump shaft and bearing assembly.
- Drop-In Replacement — Matches the original mounting pattern and bearing seat geometry of the APT6T and APT6S pump housings for a straightforward swap during scheduled service or emergency repair.
- Broad APT6 Series Coverage — Fits APT6T Surge Brake, APT6T Electric Brake, APT6T Cold Weather, APT6S w/Skid, and APT6S Cold Weather configurations under a single part number.
- Shaft and Impeller Alignment — A correctly seated bearing housing keeps the pump shaft running true, preventing premature impeller wear, vibration, and seal failure that a worn or cracked housing can cause.
- Verified Part Number — Part number 5200021730 is confirmed against the Wacker Neuson APT6T and APT6S parts documentation, so you can order with confidence that this is the right component for your machine.
The bearing housing is a structural component that supports and locates the main shaft bearings within the pump assembly. It holds the bearings in precise alignment so the impeller spins concentrically within the pump casing, which is essential for maintaining flow efficiency and seal integrity. When the bearing housing cracks, corrodes, or wears at the bearing seat, shaft runout increases — leading to accelerated bearing failure, mechanical seal leakage, and reduced pumping performance.
