This oil seal is installed on the front axle of the host tractor or vehicle. It prevents lubricant leakage and keeps contaminants out of the axle housing. A worn or hardened seal allows oil to weep past the rotating shaft, which can lead to bearing damage from insufficient lubrication. The manufacturer replicates the original seal’s lip geometry and material compound to maintain the correct interference fit with the shaft. On installation, ensure the seal bore is clean and free of burrs, and lubricate the seal lip before pressing it into place.
