Description
When you’re pulling a big planter in the heat of planting season or pushing through thick hay with your mower, the last thing you need is an overheated tractor or a fan that roars constantly even when it’s not needed. If your 6600 or 7600 series Massey has a fan that’s either stuck on full blast or won’t engage when things get hot, this viscous clutch replacement gets your cooling system working smart again.
What You’re Getting
- Temperature-sensitive viscous coupling that automatically adjusts fan speed based on actual cooling needs
- Frees up 5-15 horsepower when cooling isn’t needed – power that goes back to your drawbar or PTO
- Eliminates constant fan noise during light work or cold morning starts
- Smooth progressive engagement that won’t shock your belts and bearings
- Direct replacement for your factory clutch with no modifications needed
Built for Real Farm Work
Your 6600 and 7600 series tractors pack serious horsepower and modern technology – they deserve cooling management that’s just as sophisticated. Whether you’re running a 130-horse 6613 on the hay ground or pushing a 180-horse 7615 through heavy tillage, this clutch provides maximum airflow when you need it and backs off when you don’t.
Made to Last
Inside this clutch is precisely calibrated silicone fluid that responds to temperature changes throughout its service life. The sealed construction keeps contaminants out and maintains the exact viscosity needed for proper operation. Built to handle the constant speed changes and high rotational forces these big tractors generate.
Good to Know
Never store or handle the clutch upside down – the silicone fluid inside needs to stay in the right position. Check your fan blades for damage before installing, as a bent fan will destroy a new clutch quickly. After installation, you should hear the fan engage gradually as temperature rises, not suddenly kick in at full speed.
