This bearing bushing is a wear component within the three-point linkage of the host tractor. It provides a low-friction pivot surface between the linkage arms and their mounting pins, allowing the hitch to articulate under load. Wear at this bushing introduces play in the linkage, which reduces the precision of implement height control and can cause uneven load distribution across the hitch arms. The bushing is manufactured by AGCO to match the original housing bore and pin diameter, so no reaming or shimming is required during installation. Replace the bushing when free play at the pivot point exceeds the service limit.
