Viscous Fan Clutch for New Holland T4020-T4050/T4.75V-T4.105U & Case Farmall/Quantum Series Tractors

Description

Ever notice how your fan sounds like a freight train even on a cool morning, or worse yet, your temperature gauge starts climbing when you’re pushing hard in summer heat? That’s your viscous fan clutch telling you it needs attention. When it’s working right, you’ll barely notice it – the fan runs quiet when it’s cool and kicks in strong when things heat up, saving you fuel and horsepower while keeping your engine happy.

What You’re Getting

• Temperature-activated design that engages only when cooling is actually needed
• Saves 5-10 horsepower during normal operation compared to a locked-up fan
• Smooth, progressive engagement that won’t shock your belts and bearings
• Sealed construction with calibrated silicone fluid for years of maintenance-free operation
• Direct replacement for factory clutch – no modifications needed

Built for Real Farm Work

This clutch fits the workhorses of many operations – New Holland’s versatile T4 series and those reliable Case Farmall and Quantum tractors. Whether your T4030 starts the day doing cool morning chores then heats up pulling a heavy implement, or your Farmall 95U switches between light transport and heavy field work, proper cooling management makes all the difference in fuel costs and engine life.

Made to Last

Inside this clutch is precisely calibrated silicone fluid that responds to temperature changes throughout its service life. The robust sealed construction prevents contamination that would throw off the clutch’s response, while heavy-duty bearings handle the constant speed variations and rotational forces these hardworking tractors dish out.

Installation Notes

Handle this clutch with care – never store it on its side or upside down as the silicone fluid can migrate and affect operation. Clean your fan mounting surfaces thoroughly and check for bent blades that cause vibration. The clutch should spin freely when cold but show increasing resistance as the engine warms up. If you’re replacing due to overheating issues, check your radiator and water pump too.
