Built for Real Farm Work
Your Ford New Holland 40 series tractor—whether it’s a 5640 utility model or a big 8340 row-crop machine—depends on that Dual Power system for smooth on-the-go shifting. When you’re pulling a planter through tough ground or running a loader all day, being able to shift between high and low ranges without stopping keeps you productive and the work moving.
Made to Last
These sealing components are built to handle the 240-260 PSI operating pressure that makes the Dual Power system work. The materials resist oil breakdown and temperature extremes, so they’ll keep sealing properly through long seasons of hard use.
Installation Notes
This is a transmission-apart job that’s best left to someone who knows their way around a Dual Power system. Make sure to clean all the mating surfaces thoroughly and use fresh transmission fluid when you put it back together. Proper bleeding of the hydraulic system after installation is critical for smooth operation.
