Cross Reference Numbers

Common reference numbers may include 11Q6-90040, 11Q690040, 11Q6-90041, 11Q690041, A5W00258A, 715618, 11WC-90070 and 11WC90070.

These numbers should be used as reference numbers only. A/C compressors with similar part numbers may have different pulley diameter, clutch type, groove type, port layout, oil specification or mounting configuration. Final fitment should be verified by the old compressor label and machine serial number before ordering.

Application and Fitment Reference

This 11Q6-90040 / 11Q6-90041 Hyundai A/C compressor is mainly prepared for Hyundai excavator references such as R220-9, R330-9, R210-9 and R320-9. Public supplier references also list related Hyundai 7-series and 9-series crawler excavator applications, including models such as R140LC-9, R160LC-9, R210LC-9, R250LC-9, R300LC-9, R320LC-9 and R330LC-9 series.

Because Hyundai excavator A/C compressor configurations may vary by machine version, production year and previous repair history, the model list should be treated as a fitment reference. Please confirm the original compressor part number, voltage, pulley groove, clutch diameter, mounting points, hose port position and machine serial number before purchase.

Technical Notes

Public supplier references commonly list this compressor as a V5 type compressor with 24V voltage and 1PK / single-groove pulley. Some references list a pulley diameter around 130 mm, while other compressor catalogs list about 132 mm. Please compare the physical dimensions with the old compressor before ordering.

Oil type and oil quantity should follow the compressor label and the machine A/C service procedure. Do not mix oil specifications based only on online cross-reference numbers.

Common Failure Symptoms

• No cabin cooling: the A/C system runs, but outlet air is not cold.

• Compressor clutch does not engage: possible causes include low refrigerant pressure, pressure switch fault, fuse or relay fault, wiring issue, clutch coil failure or compressor damage.

• Abnormal noise: bearing wear, belt misalignment, low lubrication or internal compressor damage may cause noise.

• Oil or refrigerant leakage: inspect hose joints, O-rings, rear ports, compressor body, shaft seal and service valves.

• Repeated compressor failure: contamination, blocked condenser, incorrect oil amount, failed receiver drier or poor system flushing may damage the replacement compressor.

Troubleshooting Before Replacement

Before replacing the compressor, inspect the complete A/C system. A compressor failure may be caused by other system problems rather than the compressor itself.

• Check refrigerant pressure and confirm whether leakage is present.

• Inspect compressor clutch operation, belt tension and pulley alignment.

• Check A/C fuse, relay, pressure switch and wiring connector.

• Inspect condenser airflow, receiver drier condition, expansion valve and evaporator for blockage or contamination.

• Confirm the correct refrigerant, oil type and oil quantity before installation.

Installation and Maintenance Notes

• Recover refrigerant properly before removing the old compressor.

• Cap all A/C lines after removal to prevent dust and moisture from entering the system.

• Flush the A/C system if the old compressor failed internally or if metal particles are found.

• Replace the receiver drier or accumulator when installing a replacement compressor.

• Check whether the expansion valve should be replaced according to system condition.

• Use the correct refrigerant and compressor oil specified for the machine and compressor.

• Evacuate the system, check for leaks and recharge with the correct refrigerant amount.

• After installation, run the A/C system and check cooling performance, clutch engagement, abnormal noise and leakage.

Fitment Check Before Ordering

To reduce wrong orders, please send the machine model, serial number, old compressor part number, compressor nameplate photo, clutch and pulley photo, rear port photo and mounting photo before quotation. This helps confirm whether 11Q6-90040 / 11Q6-90041 is suitable for your Hyundai excavator.
