380906553 XCMG GR2605 motor grader air duct cover

380906553 XCMG GR2605 motor grader air duct cover

380906553 is an original factory-installed air duct cover for the XCMG GR2605 motor grader. It’s used to seal and protect the air ducts of the cab’s air conditioning system and the entire machine’s cooling system, ensuring proper airflow guidance, dust and water protection, and improving air conditioning efficiency and component lifespan.

Core Functions and Roles

Fixed at the duct opening, it forms a sealed airflow channel, preventing air leakage and ensuring efficient air conditioning/heating and engine cooling.

It blocks construction dust, sand, rainwater, and oil from entering the duct, protecting core components such as the fan, evaporator, and heater core.

It also functions as an inspection port, facilitating disassembly and cleaning of the duct, and replacement of internal filters and the fan, reducing the workload of disassembling the entire machine.

The original factory dimensions and clip/bolt hole positions are precise, perfectly fitting the duct and sealing strips without resonance or abnormal noise.

Key Technical Parameters

Replacement and Maintenance Points

Disconnect the power and air supply before disassembly to avoid damaging the fan blades during operation; clean debris around the duct.

During installation, clean the sealing surface, reinstall the new sealing gasket, and tighten the bolts/clips evenly diagonally to prevent localized deformation.

Regularly check the cover’s fixing status. In dusty conditions, it is recommended to clean the duct monthly and check the gasket wear at the same time.
