This friction disc is a wear component inside the tractor gearbox. It transmits torque between the clutch pack and the planetary gearset, engaging and disengaging power flow to the driveline. The disc is made from a high-grade friction material bonded to a steel core, designed to withstand the shear loads and heat generated during clutch engagement. A worn disc will cause slipping under load, delayed engagement, or gear clash during shifts. This original AGCO part is machined to the same thickness and tooth profile as the original assembly, so no shimming or adjustment is required during installation. On reinstall, ensure the mating surfaces are clean and free of oil residue.
