380900903 XCMG GR2605 motor grader rake teeth

Core Functions and Roles

1. Soil Handling: Directly contacts soil, gravel, and other materials to loosen, turn, and break up soil, improving the smoothness of the working surface and adapting to the preparation needs of different soil textures.

2. Wear and Impact Resistance: The teeth are made of high-strength wear-resistant material with a reinforced surface treatment, resisting impacts from gravel and soil friction during operation, reducing wear, and extending the service life of individual teeth.

3. Transmission Compatibility: Precisely matches the installation dimensions of the rake tooth assembly, allowing for quick connection to the assembly, transmitting power to the equipment, and ensuring smooth and stable operation.

4. High-Efficiency Operation: Optimized tooth design reduces material adhesion, improving soil clearing and material pushing efficiency, suitable for heavy-duty, high-frequency operation scenarios.

Common Faults and Troubleshooting

– Fault Symptoms: Excessive wear at the rake tooth tips, tooth cracking and deformation, loose tooth roots, material adhering to the tooth body;

– Troubleshooting Points: After stopping the machine, check the tooth body for wear, deformation, and cracking; check the tightness of the tooth root connection; clean the material adhering to the tooth body and assess the degree of wear and corrosion.

Replacement and Maintenance Points

1. Regular Inspection: After operation, check the wear, deformation, and cracking of the teeth. Replace them promptly if the wear exceeds the threshold or cracks appear.

2. Cleaning and Maintenance: After operation, promptly clean the soil, sand, and other materials adhering to the teeth to prevent corrosion and adhesion that could affect subsequent operations.

3. Installation Specifications: During installation, ensure precise alignment with the rake tooth assembly and tighten to the specified torque to prevent loosening and detachment.

4. Working Condition Adaptation: In harsh working conditions (high sand and gravel, hard soil), shorten the inspection cycle and replace damaged rake teeth promptly to ensure equipment operating efficiency.
