This shaft seal ring is installed at the output of the front axle and within the brake system of the host tractor. It prevents lubricant leakage from the axle housing and keeps contaminants out of the brake assembly. A worn or hardened seal allows fluid to reach the brake linings, reducing braking effectiveness and potentially causing axle bearing damage. This component is manufactured to AGCO's original specifications, matching the seal groove geometry of the housing to maintain the correct interference fit without additional shimming.
