This rubber bushing functions as the cushion element in the cab suspension system. It isolates the cab structure from chassis vibrations, reducing transmitted shock and noise to the operator station. The bushing sits between the cab mounting bracket and the chassis frame, compressing under load to dampen vertical and lateral movement. A worn bushing allows metal-to-metal contact, which produces audible rattling and increases vibration felt at the operator seat. Manufactured by AGCO, this bushing is formed to the original mold geometry. The rubber compound matches the original durometer, so the suspension maintains its designed spring rate and damping characteristics without requiring shimming or adapter plates. On installation, inspect the mounting bracket for corrosion or deformation before seating the bushing.
