The 11N6-90040 A/C compressor is a new aftermarket replacement for the cabin air conditioning systems used on selected Hyundai 7-Series excavators and wheel loaders. The compressor label identifies the unit as a DKV-14C with compressor part number 506221-0470.

Known applications include Hyundai R210LC-7 and R210NLC-7 excavators, together with HL730-7, HL740-7 and HL757-7 wheel loaders. Machine production versions may use different compressor configurations, so the original unit should still be checked before ordering.

Fitment Checks Before Ordering

Compare the original compressor number, DKV-14C body design, 24V clutch, mounting points, single-groove pulley, electrical connector and refrigerant port arrangement with the product photos.

For accurate identification, provide the Hyundai machine model, serial number, original compressor label and clear photos showing the pulley, connector, mounting brackets and refrigerant ports.

A/C System Checks Before Installation

Before replacing the compressor, inspect the refrigerant circuit for leakage, contamination and metal debris. Flush the system when required and inspect the receiver drier, expansion valve, hoses and condenser before installing the new unit.

Confirm the oil specification and total system oil quantity before installation. After fitting the compressor, evacuate the system, perform a leak test and recharge it with the correct amount of R134a refrigerant.
