The Wacker Neuson 5200021831 is a genuine OEM Mounting Bracket designed for the APT4S and APT4T pump series. This includes the APT4S Pump with Skid, APT4S Pump with Skid Cold Weather, APT4T Pump with Surge Brake, APT4T Pump with Surge Brake Cold Weather, APT4T Pump with Electric Brake, and APT4T Pump with Electric Brake Cold Weather configurations. As a genuine OEM component, the 5200021831 is sourced directly through Wacker Neuson and engineered to meet the exact structural and dimensional requirements of these pump assemblies. When a mounting bracket cracks, corrodes, or loses integrity, it can compromise the stability of the entire pump unit — making prompt replacement with the correct OEM part essential.
Key Features
- Genuine OEM Structural Integrity — Manufactured to Wacker Neuson's exact design tolerances, ensuring the bracket maintains proper load distribution and secure pump positioning under operating conditions.
- Direct-Fit Replacement — Designed to bolt into the same mounting points as the original, covering both Surge Brake and Electric Brake APT4T variants as well as APT4S Skid configurations.
- Broad APT4 Series Coverage — A single part number fits multiple APT4S and APT4T configurations, including standard and Cold Weather pump variants.
- Pump Stability Under Load — A correctly fitted mounting bracket keeps the pump unit firmly secured during operation, preventing vibration-induced misalignment that can accelerate wear on hoses, fittings, and seals.
- Cold Weather Variant Compatible — Verified fitment across Cold Weather-spec models, meaning the bracket is suited to installations where thermal cycling and environmental exposure are additional stress factors.
A mounting bracket provides the structural anchor point that secures the pump assembly to its skid or trailer frame. It bears the static weight of the unit as well as dynamic forces generated during pump operation and transport. When a mounting bracket becomes damaged, bent, or corroded, the pump can shift position, placing undue stress on connected hoses, fittings, and drive components — and creating potential safety and performance issues. Replacing a worn or failed bracket with the correct OEM part restores the pump's secure, stable mounting position.
