The Wacker Neuson 5200020073 Oil Cooler Complete is a genuine OEM component designed for the APT4T and APT4S series self-priming pump units, including Electric Brake, Surge Brake, and Cold Weather configurations. As a direct factory replacement, this assembly maintains the precise thermal management performance the hydraulic system depends on. Sourced directly from Wacker Neuson, part number 5200020073 ensures an exact match to the original unit installed at the factory. Compatible models include the APT4T Pump with Electric Brake, APT4T Pump with Surge Brake, APT4S Pump with Skid, and their corresponding Cold Weather variants.
Key Features
- Genuine OEM Thermal Specification: — Engineered to the same heat-dissipation capacity as the original, maintaining hydraulic fluid temperatures within the operating range required for consistent pump output.
- Complete Assembly Replacement: — Supplied as a complete cooler unit, allowing direct swap-out without sourcing individual sub-components or fabricating adapter fittings.
- Broad APT4T and APT4S Compatibility: — Fits Electric Brake, Surge Brake, and Cold Weather variants across both the APT4T and APT4S pump families, covering a wide range of trailer-mounted configurations.
- Protects Hydraulic System Integrity: — A functioning oil cooler prevents heat buildup that accelerates seal wear, degrades hydraulic fluid, and leads to pump performance loss or component failure.
- Cold Weather Configuration Ready: — Verified fitment on Cold Weather-spec machines, ensuring compatibility where thermal management demands differ from standard operating configurations.
The oil cooler in a hydraulic pump system is responsible for dissipating heat generated by the hydraulic drive circuit during operation. Without adequate cooling, hydraulic fluid temperatures rise rapidly, breaking down fluid viscosity, accelerating wear on seals and internal components, and ultimately causing the pump drive system to overheat and shut down. A worn or leaking oil cooler compromises the entire hydraulic circuit, making prompt replacement critical to maintaining consistent pump performance and protecting downstream components.
