This oil seal is installed on the front axle of the host tractor, where it retains lubricant and excludes contaminants at the rotating shaft interface. It sits between the axle housing and the hub or planetary gear set, maintaining a sealed boundary that prevents oil loss and ingress of dirt or moisture. A worn or hardened seal allows lubricant leakage, which can lead to reduced gear and bearing life due to inadequate lubrication. Corteco manufactures the seal to match the original housing bore and shaft dimensions, ensuring the interference fit and lip geometry required for proper sealing without additional shimming. On installation, inspect the shaft surface for scoring and lubricate the seal lip before pressing it into the bore.
