This air compressor supplies pressurized air to the pneumatic braking and auxiliary systems on the host tractor. It is belt-driven from the engine and mounts to a dedicated pad on the gearcase or engine block. The compressor draws filtered intake air, compresses it in a single-stage piston cylinder, and delivers it through a discharge line to the air dryer and reservoir. A worn compressor will cause slow system pressure buildup, frequent governor cycling, or insufficient brake-release pressure. This original AGCO component is machined to the same mounting flange geometry and pulley alignment as the factory assembly, so no shimming or bracket modification is needed during replacement. On reinstall, replace the intake and discharge gaskets and torque the mounting bolts to the specification for the engine platform.
