This ring is a sealing component installed in the engine assembly of the host tractor. It sits between two mating surfaces, typically at a joint or bore, to prevent oil or fluid leakage under operating pressure and temperature. A worn or deformed ring allows seepage past the joint, which can lead to gradual pressure loss and contamination of adjacent components. Manufactured by AGCO, the ring is formed to the same cross-section and material specification as the original engine seal, so it seats correctly in the groove without requiring shimming or additional sealant.
