This oil seal is installed in the drive system of the host tractor. It retains lubricating oil within the axle housing and prevents the ingress of contaminants from outside. The seal sits at the rotating shaft interface, where its lip maintains contact with the shaft surface to form a dynamic barrier. A leaking seal allows oil loss and contaminant entry, which can lead to bearing or gear damage. The seal is manufactured by Corteco to match the original housing bore and shaft dimensions, ensuring the correct interference fit and lip pressure for reliable sealing. On installation, inspect the shaft surface for scoring and lubricate the seal lip before pressing it into the housing.
