This ring is a component of the universal transport hitch (TUZ) assembly, used to secure the three-point linkage when towing implements. It sits between the hitch module and the retaining hardware, providing a precise spacing surface that maintains correct alignment of the linkage arms. A worn or missing ring allows play in the hitch assembly, which can lead to uneven load distribution and accelerated wear on the adjacent pins and bushings. The ring is manufactured to the original dimensional tolerance, matching the housing bore and the shaft shoulder so that no shimming is required during installation. When reinstalling the hitch module, inspect the ring for deformation and replace it if the contact face shows any signs of compression or edge damage.
