This sealing washer is installed on the front axle of the host tractor. It prevents fluid leakage at the interface between the axle housing and the component it seals. A degraded or missing washer allows lubricant to escape and contaminants to enter the axle assembly, leading to accelerated wear of the internal gears and bearings. The part is manufactured by AGCO to match the original seal groove geometry, ensuring proper compression and sealing force when the mating surfaces are torqued to specification.
