Built for Real Farm Work

This clutch disc kit works on a wide range of International Harvester tractors from compact utility models to high-horsepower row crop machines. Whether you’re running a 656 on dairy chores, operating a 1066 in the grain fields, or using a 4186 for heavy tillage work, this kit restores the smooth PTO engagement that makes your tractor productive. These tractors excel at running stationary equipment like grain elevators, feed mixers, and hydraulic pumps where reliable PTO operation is essential.

Made to Last

The friction materials in this kit handle heat better and resist glazing, providing consistent engagement even under demanding conditions. TISCO builds these components to withstand the constant cycling and high torque loads that independent PTO systems face during extended operations. The steel plates are precision-manufactured to maintain proper spacing and oil flow through the clutch pack.

Installation Notes

Installation requires complete transmission separation and specialized alignment tools for proper assembly, with professional installation strongly recommended due to system complexity. While you’ve got the tractor split, check your PTO drive shaft and rear seal for wear. Proper adjustment of both transmission and PTO clutch components is essential for reliable operation and getting the most life from your new clutch pack.
