Wacker Neuson 5000115939 CCW Fan 3.50 x 1.50 RH

The Wacker Neuson is a genuine OEM CCW Fan 3.50 x 1.50 RH designed for the CRT48 series ride-on concrete trowels. This counterclockwise, right-hand fan is a direct-fit replacement sourced from Wacker Neuson, ensuring it meets the exact specifications of the original component. Compatible across an extensive range of CRT48 variants — including the CRT48-35L, CRT48-35V, CRT48-33K, CRT48-34V, CRT48-31V, CRT48-37V, and CRT48-57K — this part covers both standard and power-steer configurations as well as dual-fuel and electronic steering models. As a genuine OEM part, delivers the precise airflow geometry the engine cooling system was engineered to produce.

Key Features

• Correct Rotation and Blade Geometry — Counterclockwise rotation with a right-hand 3.50 x 1.50 blade profile matches the original fan orientation exactly, maintaining designed airflow direction through the shroud.
• Genuine OEM Construction — Manufactured to Wacker Neuson's original tooling and material specifications, ensuring blade pitch, balance, and hub fitment are identical to what left the factory.
• Broad CRT48 Series Coverage — Fits a wide range of CRT48 ride-on trowel configurations including CRT48-35L, CRT48-35V, CRT48-33K, CRT48-34V, CRT48-31V, CRT48-37V, and CRT48-57K variants in standard, power-steer, dual-fuel, and EU editions.
• Sustained Engine Cooling Performance — A properly balanced and correctly profiled fan moves the right volume of air across the engine at all operating speeds, preventing thermal stress during extended finishing runs.
• Balanced for Vibration-Free Operation — Precision blade balancing eliminates vibration at the fan hub, protecting bearings and surrounding drive components over the service life of the trowel.
• Direct OEM Sourced Replacement — Supplied as part number 5000115939 under the Wacker Neuson parts program, giving you confidence in part number accuracy before the order is placed.

The cooling fan on a ride-on concrete trowel draws air through the engine compartment to regulate operating temperature during continuous use. On the CRT48 series, the fan's rotational direction, blade angle, and diameter are calibrated to the engine's airflow requirements — a mismatch in any of these dimensions reduces cooling efficiency and can lead to elevated operating temperatures over long finishing sessions. A worn, cracked, or imbalanced fan blade disrupts airflow and introduces vibration into the drivetrain, which accelerates wear on adjacent components. Replacing a failed fan with the correct Wacker Neuson 5000115939 CCW Fan 3.50 x 1.50 RH restores the intended cooling capacity and smooth operation the CRT48 was designed to deliver.
