This oil seal ring fits the front axle housing of the host tractor. It sits at the axle shaft exit point, retaining lubricating oil inside the hub and preventing dirt and moisture from entering the bearing cavity. A worn or hardened seal allows oil to weep past the shaft, leading to bearing lubrication loss and eventual hub damage. This component is manufactured to match the original seal's lip geometry and interference fit, so it seats correctly in the housing bore without modification. On installation, ensure the sealing surface on the shaft is clean and free of grooves; lubricate the seal lip before pressing it into place.
