This clutch basket shim set adjusts the axial clearance between the clutch pack and the pressure plate within the drivetrain. The shims sit between the clutch basket and the gearbox input shaft, controlling the stack height that determines clutch engagement timing. A worn or incorrect shim stack causes clutch slip or incomplete disengagement, leading to gear clash and accelerated wear on the synchronizers. As an original AGCO component, the shims are machined to the same thickness tolerance as the original assembly, so no additional shimming or measurement is required during installation. Replace the shims as a set when rebuilding the clutch; verify the clearance with a feeler gauge after installation.
