This friction disc is a wear component located in the drivetrain and PTO assembly. It transmits torque through friction between rotating and stationary surfaces, allowing the PTO to engage and disengage smoothly. As the disc wears, the friction material thins, which can lead to clutch slip, reduced torque transfer, and eventual failure of the PTO engagement. This original part is manufactured to the same material composition and surface finish as the component it replaces, preserving the original engagement timing and clamp load. On installation, ensure the mating surfaces are clean and free of oil or debris.
