Description
When your fan’s either roaring constantly or leaving your tractor running hot, you know the viscous clutch has quit doing its job. This smart part automatically adjusts fan speed based on what your engine actually needs – engaging fully when you’re working hard in summer heat, but freewheeling during light work or cold starts to save fuel and reduce noise.
What You’re Getting
- Temperature-activated coupling that engages the fan only when cooling is needed
- Saves 10-20 horsepower that would otherwise be wasted driving a locked fan
- Quieter cab operation during normal work – no more constant fan roar
- Precision-sealed design prevents fluid loss that causes gradual failure
- Direct replacement for your John Deere – no modifications needed
Built for Real Farm Work
Your 2955, 3050, 3055, and 3350 tractors handle everything from loader work to heavy field operations. Whether you’re baling hay on hot afternoons or doing light transport work, this clutch automatically adjusts cooling to match the workload. When you’re pushing hard, it locks up for maximum airflow. During easier tasks, it freewheels to return power to your PTO or drawbar where you need it.
Made to Last
Inside this clutch is temperature-sensitive silicone fluid that thickens as heat increases, progressively engaging the fan. The sealed construction prevents the fluid loss that makes old clutches either stick engaged or quit working altogether. Heavy-duty bearings handle the constant speed changes and rotational forces these tractors demand.
Installation Notes
Never store or handle this clutch upside down – the internal fluid needs to stay in position. Check your fan blades for damage before installing, since a bent fan will destroy a new clutch quickly. The unit should spin easily when cold and gradually engage as the engine warms up to operating temperature.
