The Wacker Neuson 5200021743 is a genuine OEM Bearing Housing designed for the APT8T and APT8S submersible pump series, including Cold Weather variants. Sourced directly from Wacker Neuson, this part carries the same specifications as the component installed at the factory, ensuring a correct drop-in fit within the pump assembly. Compatible across the full APT8T and APT8S lineup — covering Surge Brake, Electric Brake, skid-mounted, and Cold Weather configurations — this housing supports the rotating shaft assembly that keeps these pumps running at full capacity.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's exact tolerances for the APT8 pump family, ensuring the shaft and bearing seat align correctly and maintain proper load distribution throughout operation.
- Direct-Fit Replacement — Matches the original mounting points and interface dimensions of the APT8T and APT8S pump housings, allowing straightforward installation without modification.
- Broad APT8 Series Coverage — Fits the APT8T Surge Brake, APT8T Electric Brake, APT8S with Skid, and all corresponding Cold Weather variants, making it the correct choice across the APT8 platform.
- Protects Shaft and Bearing Integrity — A failed or worn bearing housing allows shaft misalignment and accelerated bearing wear, leading to pump vibration, seal failure, and eventual pump seizure. Replacing it promptly restores correct shaft support and extends pump service life.
- Verified Part Number — Order with confidence using Wacker Neuson part number 5200021743, cross-referenced against all listed APT8T and APT8S machine configurations.
The bearing housing is a structural component within the pump's rotating assembly that locates and supports the main drive shaft bearings. It holds the bearings in precise alignment, transferring rotational loads away from the shaft and into the pump body so the impeller can move water efficiently without excessive vibration or wear. When the bearing housing becomes cracked, corroded, or worn beyond tolerance, bearing movement increases, shaft alignment is lost, and the seals around the shaft begin to fail — allowing water ingress that can damage the motor and bring the pump out of service entirely.
