Product Specifications:

OEM Hustler Turf Equipment Part | Application: Hydrostatic Transmission Cooling & Drive | Kit Includes: 7.0" Fan, Pulley Disc, Hub & Lock Nut | Transmission: Hydro-Gear

This genuine factory service kit is designed to replace worn or damaged cooling fans and drive pulleys on select Hustler zero-turn riding mowers equipped with Hydro-Gear hydrostatic transmissions. As a complete dual-side refreshing kit, it delivers the necessary OEM components to restore optimal thermal regulation, safeguard internal transaxle pressures, and maintain consistent power transfer across both hydraulic drive assemblies.

Hardware & Maintenance/Inspection Notice:

• When replacing damaged transmission fans, always inspect the tension level of your pump drive belt, the free spin of the alignment idler pulley, and the structural loading of your tensioner spring.
• Faulty belt tracking, misaligned pulleys, or debris buildup can lead to premature belt wear, blade clipping, or sudden fan blade fracture.
• Need replacement hydro drive belts, idler pulleys, or tension springs? Check our "You May Also Like..." section below for matched genuine service components.

Serial/VIN Verification Reminder: Always confirm exact fitment using your machine's 6-digit model/SKU number tag located on the frame ID label prior to ordering.
