The Wacker Neuson Water Pump is a genuine OEM component designed for the CRT36, CRT48, and CRT60 series ride-on concrete trowels. As a direct OEM replacement, is manufactured to the same specifications as the original part, ensuring correct installation and consistent engine cooling performance across the full range of compatible machines. This water pump fits an extensive lineup of CRT models including the CRT36-24A, CRT36-25, CRT36-26A, CRT48-33K, CRT48-34V, CRT48-35L, CRT48-35V, CRT48-37V, CRT48-57K, and CRT60-66K through CRT60-74LX — covering both standard and Power Steer configurations. Whether you're servicing a 915mm/36in or 1220mm/48in ride-on trowel, the Wacker Neuson is the correct part for the job.
Key Features
- Genuine OEM Cooling Circuit Integrity — Manufactured to original Wacker Neuson specifications, maintaining proper coolant flow rate and impeller geometry for the engine cooling system in CRT ride-on trowels.
- Direct-Fit Replacement — Matches the original mounting flange, port sizing, and shaft dimensions for a bolt-on installation with no rework to existing hose connections or engine brackets.
- Broad CRT Series Coverage — A single part number covers CRT36, CRT48, and CRT60 models across multiple build variants including standard, Power Steer, Dual-Fuel, and EU-specification configurations.
- Sustained Engine Temperature Control — A correctly functioning water pump keeps coolant circulating at the right flow rate; a failed or worn pump leads to engine overheating, which can cause costly mid-pour shutdowns on time-critical flatwork operations.
- Engine Protection Compliance — Maintaining proper coolant circulation is essential to safe engine operation; using the correct OEM pump prevents overtemperature conditions that can trigger engine protection shutdowns or cause internal engine damage.
The water pump circulates engine coolant through the cooling system, drawing heat away from the engine block and cylinder head and dissipating it through the radiator. On ride-on concrete trowels like the CRT series — where the engine operates under sustained load during finishing runs — consistent coolant flow is critical to keeping the engine within its safe operating temperature range. When a water pump begins to fail, symptoms include coolant leaks at the pump housing, rising engine temperature readings, and ultimately engine overheating; left unaddressed, a failed pump can cause significant internal engine damage and force costly unplanned downtime on the slab.
