When your clutch starts slipping during heavy field work or you can't get clean gear shifts when operating your PTO equipment, it's time for a proper clutch replacement. This LUK split torque clutch assembly gives you the heavy-duty performance your Massey Ferguson was designed to deliver, whether you're pulling a disc or running a grain elevator. What You're Getting Complete LUK 12-inch assembly with pressure plate, disc, and release bearing for one-stop installation Split torque design lets your PTO operate independently of the transmission clutch - crucial for stationary work Cable-operated system provides direct, responsive clutch control without hydraulic complications OEM-quality construction that handles the torque and heat your tractor dishes out 1 5/8 inch spline with 25 splines matches your input shaft perfectly Built for Real Farm Work This assembly fits the workhorse tractors in Massey Ferguson's lineup - the 300 series utility models like the 362, 365, 375, and 390, plus the heavier 4200 and 4300 series tractors that handle serious field work. The split torque system is what makes these tractors so valuable for mixed operations where you need to run PTO equipment while parked. Made to Last LUK has been building clutches for decades, and this isn't some budget replacement. The pressure plate provides consistent clamping force, the disc material handles heat without glazing, and the whole assembly is engineered to work as a system. You'll get thousands of hours out of this setup when installed properly. Good to Know This is major mechanical work - the tractor needs to be split between engine and transmission for installation. Most folks have their dealer or a qualified shop handle this job since proper alignment and torque specs are critical. The input housing seal kit (part 63458) is highly recommended while you're in there to prevent future leaks.
