Description

When you’re running your Favorit 500 hard all day—whether pulling implements or running the loader—you need a cooling system that’s as reliable as the rest of the machine. This viscous fan clutch is the brain of your cooling system, automatically engaging the fan when needed and freeing up valuable horsepower when it’s not. If you’re hearing that fan roaring constantly even in cool weather or your temperature gauge is climbing higher than usual, it’s time to replace this critical component.

What You’re Getting

Temperature-activated viscous coupling that provides automatic fan speed control based on actual engine needs
Smart design that typically saves 5-10 horsepower during normal operation compared to a locked fan
Progressive engagement that provides exactly the cooling needed – never more, never less
Hermetically sealed construction that maintains precise calibration for the life of the unit
Smooth operation that extends belt and component life by preventing shock loads

Built for Real Farm Work

Your Favorit 500 series tractor is built for versatility, handling everything from field work to loader operations around the farmyard. These mid-range tractors work hard in varying conditions, making smart cooling management essential. Whether you’re cultivating on hot summer days or doing chores in cool morning air, this viscous clutch adapts to keep your engine at optimal temperature while maximizing fuel efficiency.

Made to Last

Inside this viscous clutch is a precisely calibrated system using temperature-sensitive silicone fluid that remains thin when your engine is cold, allowing the fan to slip and reducing power draw to almost nothing. The robust construction handles the constant temperature variations and operational demands of farm work, delivering reliable performance season after season.

Good to Know

Never turn the clutch upside down or store it on its side, as this can cause the silicone fluid to migrate and affect performance. Before installation, inspect your fan blades for damage or imbalance – a bent fan will destroy a new clutch quickly. After installation, the clutch should spin easily when cold but gradually engage as the engine warms, with fan speed increasing with temperature.
