Agco - 716100420051 - Half Ring of Clutch Shaft Massey Ferguson

This clutch shaft half-ring is a locating component that secures the clutch shaft within the drivetrain assembly. It sits in a machined groove on the shaft, preventing axial movement while allowing the shaft to rotate freely. The half-ring is a precision-formed part that must match the groove dimensions exactly to maintain correct clutch engagement and disengagement timing. A worn or incorrectly seated half-ring can allow the shaft to shift axially, leading to clutch drag, incomplete disengagement, or premature release bearing wear. As an original component from the drivetrain manufacturer, it is formed to the same groove profile and hardness as the part it replaces, so no shimming or modification is needed during installation.
