This oil seal fits on the front axle of the host tractor, where it retains lubricant and excludes contaminants from the hub or differential area. It sits between the rotating shaft and the stationary housing, forming a contact seal that prevents oil leakage and keeps dirt from entering the bearing cavity. A worn seal allows lubricant to weep past the lip, which can lead to bearing damage and eventual axle failure if not replaced. The seal is manufactured by Carraro to match the original assembly's lip geometry and housing fit, so no additional shimming or adapter rings are required. On installation, ensure the seal lip faces the lubricant side and that the housing bore is clean and free of burrs.
