This needle roller bearing supports the gearbox countershaft in agricultural tractors. It is a caged full-complement bearing that handles radial loads from the meshing gear teeth. The bearing sits between the shaft journal and the housing bore, maintaining gear alignment under load. A worn bearing produces gear whine and axial play that can lead to tooth chipping or shaft fretting. This original AGCO part is manufactured to the same internal clearance and cage geometry as the bearing fitted during gearbox assembly, so no selective shimming is required during installation. Press the bearing into the housing bore and seat it against the shoulder before inserting the shaft.
