The Wacker Neuson is a genuine OEM Clockwise Fan 3.50 x 1.50 Left Hand designed for the CRT48 series ride-on concrete trowels. This part is sourced directly from Wacker Neuson, meaning it meets the exact dimensional and rotational specifications of the original component installed at the factory. Fitment covers a wide range of CRT48 variants including the CRT48-35L, CRT48-35V, CRT48-34V, CRT48-33K, CRT48-37V, CRT48-57K, and associated Power Steer, Dual-Fuel, Electronic Steering, and EU-specification models. When you need a verified direct replacement for your ride-on trowel's cooling fan, part number is the correct OEM choice.
Key Features
- Correct Rotational Direction: — Left-hand, clockwise configuration matched exactly to the CRT48 fan housing — installing the wrong rotation causes inadequate airflow and overheating.
- OEM-Specified Blade Geometry: — At 3.50 x 1.50 inches, blade pitch and diameter are engineered to deliver the airflow volume the CRT48's engine cooling system requires at operating RPM.
- Genuine Wacker Neuson Part: — Manufactured to OEM specification; no guesswork on material grade, blade count, or hub fitment — it installs the same way the original did.
- Broad CRT48 Series Coverage: — A single part number covers CRT48-35L, CRT48-35V, CRT48-34V, CRT48-33K, CRT48-37V, CRT48-57K, and multiple sub-variants including Power Steer and EU-spec models.
- Engine Protection Through Proper Cooling: — A damaged or incorrect fan reduces cooling efficiency, leading to elevated engine temperatures and accelerated wear on seals, gaskets, and internal components.
The cooling fan on a ride-on concrete trowel draws air across the engine to regulate operating temperature during sustained finishing work. Because trowel engines run at steady RPM for extended periods, consistent airflow is critical — a fan that is worn, cracked, or installed in the wrong rotational direction will underperform and allow heat to build up in the engine bay. The left-hand, clockwise orientation of the Wacker Neuson 5000115940 is specific to the CRT48 platform; using a fan with incorrect rotation or the wrong blade dimensions will move less air than the system requires, shortening engine life and potentially causing thermal shutdown mid-pour.
