This set of spacer washers is an original AGCO component for the drive system of the host tractor. The washers are installed between rotating and stationary parts to establish precise axial clearance, preventing unwanted movement that can cause misalignment or premature wear on gears and bearings. A worn or incorrectly stacked set of washers introduces end-play in the shaft assembly, which leads to gear noise and reduced power transmission efficiency. The original part is machined to the same thickness tolerance as the factory assembly, so no shimming or adjustment is needed during installation.
