This cab mounting spacer bushing positions the cab structure on the tractor chassis and maintains the correct gap between the mounting bracket and the frame rail. It sits at each cab-mount point, distributing clamping load from the mounting bolt across the bushing face. A worn or collapsed bushing allows cab movement that transfers vibration into the operator station and can cause misalignment of the cab-to-chassis seals. This original AGCO part is machined to the same height and bore tolerance as the factory-installed bushing, so no shimming is required during replacement. On reinstall, clean the mounting surfaces and torque the cab-mount bolts to the specification for the host tractor.
