231-6984 A C Compressor — Cat 320C

This A/C compressor is the heart of the vehicle's air conditioning system, responsible for circulating refrigerant to cool the cabin. It is built to meet stringent OEM performance and durability standards, providing efficient cooling unlike a worn compressor that may produce insufficient cooling or excessive noise. Operators will typically notice a lack of cold air, unusual noises from the compressor pulley, or a burning smell when this unit begins to fail.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first sign of a failing A/C compressor is usually a noticeable decrease in cooling performance, with the cabin air not getting as cold as it should. This can progress to include loud grinding or squealing noises from the compressor pulley area, and potentially a refrigerant leak. If the compressor fails completely, the air conditioning system will cease to provide any cooling, leading to discomfort for the operator and potential heat-related issues for onboard electronics.

Installation Tip

Ensure the A/C system is properly evacuated of all refrigerant before removing the old compressor to comply with environmental regulations and safety standards. Never overtighten the compressor mounting bolts, as this can warp the compressor housing.

Service Note

Flush the A/C system thoroughly and replace the receiver-drier and expansion valve or orifice tube when replacing the compressor.
