Genuine Air Conditioning Compressor for LiuGong Wheel Loaders 49C9469
Primarily designed for LiuGong medium-to-large wheeled loaders, such as mainstream models including the CLG856H, 856H Max, 855N, 848H, 870H, and CLG835.
FUNCTION
1. Powerful Suction and Refrigeration: During operation, the compressor utilizes its intake valve to forcefully draw the low-temperature, low-pressure gaseous refrigerant-which has just evaporated and vaporized within the evaporator-into its internal chamber, thereby maintaining a continuous flow throughout the entire air conditioning circuit.
2. Gas Compression and Energy Conversion: Driven by a belt connected to the loader's engine, the compressor's internal pistons or rotors forcefully compress the intake refrigerant gas. This process transforms the low-pressure gas into a high-temperature, high-pressure gaseous refrigerant, which is then discharged through the exhaust valve to the external condenser, preparing it for the subsequent heat dissipation and release phase.
3. Rapid Cab Cooling: This compressor is specifically engineered for the cabs of heavy machinery-environments characterized by extensive glass surfaces and high thermal radiation. Leveraging its highly efficient circulation capabilities, the system delivers a cooling output of up to 5.6 kW, enabling it to rapidly lower the temperature inside the operator's cab within just a few minutes, even under the intense exposure of scorching summer sunlight.
4. Dehumidification and Defrosting Functions: Under harsh operating conditions-such as those involving high humidity, heavy rainfall, or significant temperature differentials-activating the compressor rapidly condenses the moisture present in the cab's air, thereby providing a highly effective dehumidifying effect.
Installation Location
Bottom/Side: Immediately adjacent to the engine crankshaft pulley and alternator.
Front: Directly facing the engine's cooling fan blades.
Top: Equipped with a belt tensioner, used to adjust the tightness of the drive belt.

Routine Maintenance Recommendations
1. Regular Cleaning of Condenser and Filters: Construction sites generate a significant amount of dust. It is mandatory to use a low-pressure water spray or compressed air every week to clean the condenser (located at the rear of the vehicle) and the cab's air conditioning filter. Poor heat dissipation leads to excessive system pressure, which can directly burn out the compressor's electromagnetic clutch.
2. Check Belt Tension and Alignment: Inspect the drive belt every 250 operating hours. Firmly press down on the center of the belt with your finger; the optimal deflection is between 10–15 mm. A belt that is too tight can damage the compressor bearings, while a belt that is too loose will cause slippage and overheating.
3. Periodic Operation During the Off-Season: During winter or seasons when cooling is not required, the air conditioning system should be manually activated and run for 5–10 minutes every two weeks. This allows the refrigerant oil to circulate throughout the system, lubricating the internal pistons and rubber shaft seals, thereby preventing refrigerant leaks and internal corrosion.
4. Strictly Prohibited: Starting the Vehicle with the A/C On You must turn off the air conditioning switch (A/C) every time before shutting down the engine. If the engine is started while the A/C is engaged, the immense instantaneous shock generated during startup can easily shatter the internal valves within the compressor.
