Viscous Fan Clutch for Massey Ferguson 6465-6480 and 7465-7480 Series with SISU Engine SKU: QT64818

When your cooling fan runs constantly, you're wasting 15-20 horsepower that should be working at the PTO or drawbar. A failed viscous clutch either won't engage when you need cooling or stays locked on when you don't. This temperature-controlled clutch automatically engages the fan only when cooling is needed, optimizing both performance and fuel efficiency.

Why SISU-Specific Engineering Matters

• Engineered specifically for SISU engine operating characteristics and engagement temperatures
• Automatically adjusts fan speed based on temperature to reduce fuel consumption and noise
• Returns 15-20 horsepower to your work when cooling isn't needed
• Reduces belt wear and extends component life through smart engagement

A reliable replacement that keeps your high-horsepower Massey Ferguson running at peak efficiency. When your fan operation doesn't match your cooling needs, this is the fix that restores proper thermal management to your SISU-powered tractor.
