This rear axle bearing bushing is an original AGCO component designed for installation in the rear planetary gear of the host tractor. It functions as a wear surface between the rotating shaft and the stationary housing, maintaining correct gear alignment within the final drive assembly. A worn bushing allows shaft play that leads to gear tooth misalignment and increased noise from the planetary set. The bushing is machined to the same inner and outer diameter tolerances as the original assembly, which eliminates the need for selective fit or shimming during installation. On reinstall, ensure the bearing journal and housing bore are clean and free of burrs to avoid distorting the bushing.
