This sealing ring is installed at the gearbox shaft exit to prevent lubricant leakage and keep contaminants out of the transmission housing. It sits in the bore between the rotating shaft and the stationary housing, forming a dynamic seal that maintains oil pressure inside the gearbox. A worn or hardened ring allows oil to weep past the shaft, leading to low lubricant levels and potential gear or bearing damage. As an original AGCO component, the seal lip profile matches the original shaft surface finish, so no break-in period or additional shimming is required. On installation, ensure the sealing lip faces the lubricant side and that the housing bore is clean to avoid tearing the lip during assembly.
