The Wacker Neuson Water Pump is a genuine OEM water pump designed for the BL744ch, BL744h, BL742h, BL744c, and BL744 EX Backhoe Loader series. As a factory-sourced component, it meets the exact specifications of the original part fitted to these machines at the time of manufacture. This OEM designation means you're getting the same part built to the same tolerances — no guesswork on compatibility across the BL700-series lineup. If your backhoe loader is showing signs of overheating or coolant circulation loss, the is the correct direct replacement to restore proper cooling system performance.
Key Features
- Genuine OEM Cooling Performance — Engineered to deliver the correct flow rate and pressure for the BL700-series cooling system, maintaining consistent engine temperature under load.
- Direct-Fit Installation — Matches the original mounting configuration and port dimensions of the factory water pump, allowing a straightforward swap with no machining or adaptation.
- Broad BL700-Series Compatibility — Fits the BL744ch, BL744h, BL742h, BL744c, BL744 EX, and BL742 EX Backhoe Loaders, covering the full range of this Wacker Neuson loader family.
- Protects Engine Longevity — A fully functioning water pump keeps coolant circulating efficiently through the engine; a worn or failed pump leads to overheating, potential head gasket damage, and costly engine repairs.
- Factory Part Number Assurance — Ordered and supplied under OEM part number 5100032589, so you can be confident you're sourcing the exact component specified by Wacker Neuson for these models.
The water pump is responsible for circulating coolant through the engine block and radiator, regulating operating temperature and preventing heat buildup during work cycles. On a backhoe loader like the BL700 series, which operates under sustained hydraulic and engine loads, a properly functioning water pump is essential to keeping the engine within its safe temperature range. When the pump begins to fail — through bearing wear, impeller damage, or seal deterioration — coolant flow is reduced, engine temperatures climb, and the risk of serious internal engine damage increases significantly.
