This engine oil seal is an original AGCO component designed to prevent lubricant leakage from the crankshaft or camshaft opening in the engine block. It sits in the bore between the rotating shaft and the stationary housing, maintaining a fluid-tight barrier that keeps oil inside the sump and contaminants out. A worn seal allows oil to weep or drip, which can lead to low oil pressure and accelerated bearing wear if not addressed. The seal is manufactured to the same bore and shaft interface dimensions as the original assembly, ensuring it seats correctly in the housing groove without requiring shimming or modification. On installation, inspect the shaft surface for scoring and lubricate the seal lip before pressing it into place.
