This air conditioning compressor circulates refrigerant through the tractor cabin's cooling loop. It is belt-driven from the engine and compresses low-pressure vapor into high-pressure gas that then flows to the condenser. A worn or leaking compressor reduces system pressure, leading to insufficient cabin cooling and potential damage to the drier or expansion valve. This compressor is manufactured by TCCI, which supplies original equipment for this application; its mounting flange and pulley alignment match the original assembly, so no bracket modifications are needed. On installation, replace the receiver-drier and O-rings at all connections, and evacuate the system before charging.
