This oil seal is installed in the wet clutch and gearbox assemblies of the host tractor. It prevents pressurized oil from leaking past the rotating shaft, maintaining the hydraulic pressure required for clutch pack engagement and gear lubrication. The seal sits between the rotating shaft and the stationary housing; a worn seal allows oil to bypass, leading to clutch slip, gear noise, or low system pressure. Corteco manufactures this seal to match the original housing bore and shaft diameter, preserving the interference fit that keeps the sealing lip in contact with the shaft surface. On reinstall, ensure the seal bore is clean and free of burrs, and seat the seal squarely to avoid lip damage.
