This bushing is the pivot interface between the lift arm and the three-point hitch linkage. It sits inside the lift arm eye, allowing the arm to rotate freely around the hitch pin during implement raise and lower cycles. The bushing is the wear surface in this joint; as it wears, the clearance between the arm and the pin increases, producing a clunking sound and causing uneven implement lift. This original AGCO component is machined to the same internal and external diameters as the original assembly, so it seats without the need for shimming or reaming. On installation, ensure the bushing is fully seated in the arm bore and lubricate the inner surface before inserting the pin.
