Viscous Fan Clutch for Massey Ferguson 6480-6499 & 7480-7499 High HP Series Tractors

Description

When your high-horsepower Massey Ferguson starts running hot or you notice the fan roaring constantly even in cool weather, it’s time to replace that viscous fan clutch. This temperature-sensitive component is the brain of your cooling system, automatically engaging the fan when needed and freeing up valuable horsepower when it’s not. Your big MF deserves cooling that’s as smart as the rest of the machine.

What You’re Getting

• Precision viscous coupling that responds to actual temperature conditions – it knows when to work hard and when to take it easy
• Saves fuel and increases available power when cooling isn’t needed – every horsepower counts when you’re pulling heavy implements
• Progressive engagement prevents shock loads on belts and bearings – your drivetrain will thank you
• Sealed unit maintains calibration throughout service life – no adjustments or maintenance required
• Direct replacement for high-horsepower 6400 and 7400 series models – bolts right in place of the original

Built for Real Farm Work

This viscous fan clutch fits Massey Ferguson models 6480, 6485, 6490, 6495, 6497, 6499 in the 6400 series and 7480, 7485, 7490, 7495, 7497, 7499 in the 7400 series. These high-horsepower tractors generate significant heat and require precise cooling management. Whether you’re running a big disc, pulling a wide planter, or powering a heavy baler, this clutch ensures your cooling system works as hard as you do.

Made to Last

Inside this clutch is specially formulated silicone fluid that thickens with heat to engage the fan progressively. This intelligent operation can free up 10-15 horsepower during normal operation compared to a direct-drive fan. The robust sealed construction prevents contamination that would alter the clutch’s carefully calibrated response, ensuring years of maintenance-free operation.

Installation Notes

When installing, never lay the clutch on its side or upside down – this can cause the silicone fluid to migrate and affect operation. Check fan blade condition and balance – a damaged fan will quickly destroy a new clutch. The clutch should spin freely when cold but show increasing resistance as it warms. Installation typically takes about an hour.
