The Wacker Neuson 5200021713 is a genuine OEM Bearing Housing designed for the APT4T and APT4S pump series, including Surge Brake, Electric Brake, and Cold Weather configurations. As a direct OEM replacement sourced from Wacker Neuson, this part meets the original design specifications for the pump's rotating assembly and shaft support system. It is compatible across multiple APT4T and APT4S variants, making it a versatile stocking part for operators and service technicians running these trailer-mounted pumps. Always verify your machine's model number before ordering to confirm fitment.
Key Features
- Genuine OEM Construction — Manufactured to the original design tolerances that govern bearing seat diameter and housing alignment, ensuring the bearing seats correctly and rotates true within the pump assembly.
- Drop-In Replacement — Matches the original housing geometry and bolt pattern, so it installs directly into the pump's bearing support cavity without modification to surrounding components.
- Broad APT Series Compatibility — Fits APT4T (Surge Brake and Electric Brake) and APT4S (w/Skid) variants, including Cold Weather-configured models, covering a wide range of trailer pump setups in one part number.
- Protects Pump Shaft Integrity — A correctly seated bearing housing keeps the shaft aligned and supported under load; a worn or cracked housing allows shaft deflection that accelerates bearing failure and can damage the pump impeller.
- Backed by Wacker Neuson OEM Sourcing — Supplied as genuine Wacker Neuson inventory, so the material grade and dimensional spec match what left the factory originally.
The bearing housing is the structural component that locates and retains the main shaft bearing within a pump's drive assembly. It holds the bearing in precise alignment so the impeller shaft spins concentrically under the stresses of continuous pumping operation. When the housing cracks, wears out of round, or corrodes, the bearing loses its proper seat, leading to shaft wobble, premature bearing failure, seal damage, and ultimately pump shaft failure — making timely replacement critical to keeping the unit in service.
