803190351 XCMG GR2605 motor grader lockable air filter

803190351 XCMG GR2605 motor grader lockable air filter

803190351 is an original factory-installed lockable air filter assembly for the XCMG GR2605 grader. Installed in the engine intake system, it combines high-efficiency air filtration with anti-theft and anti-misoperation locking functions to prevent dust from entering the cylinders, avoid malicious damage on construction sites or loosening due to vibration, and ensure long-term stable engine operation.

Core Functions and Effects

Multi-stage High-efficiency Filtration: Filters out dust, sand, and impurities from the air, protecting precision components such as engine cylinders and piston rings, reducing wear, lowering fuel consumption, and extending engine life.

Locked Anti-dismantling and Anti-theft: Integrates a dedicated locking mechanism to prevent filter theft and unauthorized disassembly leading to improper installation, while also preventing loosening of the housing and oil/dust leakage during heavy-duty operations.

Unobstructed Airflow and Pressure Differential Protection: A rational flow channel design minimizes pressure drop, ensuring sufficient airflow; coupled with a blockage alarm, it promptly prompts for filter cleaning/replacement.

Waterproof and Dustproof Sealing: Excellent housing sealing structure resists rainwater and splashing mud, suitable for harsh outdoor working conditions.

Key Technical Parameters

Model: 803190351
Name: Lockable Air Filter (Air Filter Assembly)
Compatible Model: XCMG GR2605 Grader
Material: High-strength engineering plastic shell + composite high-efficiency filter paper element; lock is made of rust-resistant metal
Features: Original factory size, high filtration accuracy, large dirt holding capacity, reliable locking, precise installation interface, compatible with alarm systems, vibration and impact resistant.

Replacement and Maintenance Points

Stop the machine and turn off the engine. Unlock and open the shell according to specifications, remove the old filter element, and clean the inside of the shell. Never use high-pressure air to directly blow on the inside of the filter element.

Replace with new original factory inner and outer filter elements, ensuring the sealing ring is installed correctly and without twisting; reset and lock the locking mechanism.

Maintenance Cycle: Perform maintenance according to the manufacturer’s manual under standard operating conditions. For construction sites with heavy dust, the cycle must be shortened; check and handle immediately when the warning light illuminates.

Avoid using inferior filter elements to prevent filter paper damage that could lead to premature engine wear.
