Multiquip 67991 14" Fan Only

The Multiquip 67991 is a genuine OEM 14" Fan Only designed for Whiteman ride-on power trowel models STXD6i, HTXD6i, STX55Y6, and STX55J6. As a direct OEM replacement sourced through Multiquip's authorized parts program, this fan is manufactured to the same specifications as the original component installed at the factory. Sourcing the correct fan for your ride-on trowel ensures proper airflow to the engine and drivetrain, keeping your machine performing at its rated capacity on the finishing floor. Verify your model code before ordering — this part is confirmed to fit the STX and HTX series hydrostatic trowels listed above.

Key Features

• OEM-Matched Airflow Performance — Built to the exact blade pitch, diameter, and hub spec of the original 14" fan, ensuring the correct volume of cooling air reaches the engine under full load.
• Direct Drop-In Replacement — Mounts using the same hub interface as the factory fan, so installation on compatible STX and HTX series trowels requires no modification to brackets or fasteners.
• Confirmed Fitment for STX and HTX Hydrostatic Trowels — Verified for STXD6i, HTXD6i, STX55Y6, and STX55J6 Whiteman ride-on power trowels.
• Protects Engine and Hydraulic Components — A correctly functioning fan maintains operating temperatures within spec; a cracked, bent, or missing fan blade leads to overheating and accelerated wear on the engine and hydraulic system.
• Genuine Multiquip OEM Part — Supplied under part number 67991, this is an authentic Multiquip component, not a generic substitute, ensuring material grade and balance match what the machine was designed around.

The cooling fan on a ride-on power trowel draws air across the engine and surrounding drivetrain components to manage heat generated during extended finishing runs. On hydrostatic trowels like the STX and HTX series, maintaining proper operating temperature is critical to protecting the hydraulic system that controls both blade pitch and machine drive. When a fan becomes cracked, unbalanced, or broken, cooling efficiency drops sharply, which can cause the engine to run hot, reduce hydraulic performance, and ultimately force unplanned downtime in the middle of a pour.
