This oil seal is installed on the front axle of the host tractor. It prevents lubricant leakage from the axle housing and keeps contaminants from entering the bearing cavity. The seal sits between the rotating shaft and the stationary housing, relying on a flexible lip to maintain contact under normal operating conditions. A worn seal allows oil to weep past the lip, which can lead to bearing damage if the lubricant level drops. The seal is manufactured by Corteco to match the original housing bore and shaft dimensions, so no modifications are needed during installation. Ensure the sealing surface on the shaft is clean and free of grooves before fitting the new seal.
