This seal ring fits the front axle housing of the host tractor. It prevents lubricant leakage and blocks contaminants from entering the axle assembly at the rotating shaft interface. A worn or hardened seal allows oil seepage past the lip, which can lead to bearing damage from reduced lubrication or dirt ingress. The manufacturer machines the sealing lip to the same profile as the original assembly, so it seats correctly in the housing bore without requiring shimming or adapters. On installation, ensure the bore is clean and free of burrs, and lubricate the seal lip before sliding it over the shaft.
