This flat ring functions as a sealing and spacing element between components in the front axle and drive system of the host tractor. It sits at a joint where two machined faces meet, preventing fluid leakage and maintaining the correct axial clearance between rotating and stationary parts. The ring is compressed during assembly, so its thickness directly controls the preload on the bearing or seal stack behind it. A worn or crushed ring reduces clamping force, which can lead to oil seepage and eventual bearing play. As an original AGCO part, the ring is manufactured to the same thickness tolerance as the original assembly, so no shimming or adjustment is needed during replacement. On installation, ensure the mating surfaces are clean and free of burrs.
