3.4.1 Removing Old Components

1. Based on your motorcycle model and the old component's mounting location, first wipe the old component and surrounding areas with a cloth to remove surface grease, dust, and debris, facilitating identification of removal points.
2. Using appropriate tools, slowly remove bolts, nuts, clips, and other fasteners securing the old component. During disassembly, note the position and quantity of each fastener to prevent loss or misplacement. (Taking photos for reference is recommended).
3. If fasteners are seized or rusted during removal, spray a small amount of rust remover on the connection point. Wait briefly before attempting removal. Never force the parts, as this may damage bolts, threads, or motorcycle components.
4. Gently remove the old part. Note its installation orientation, angle, and connection relationships with surrounding components to serve as a reference for installing the new part. After removal, clean the mounting surface and connection points with a cleaner to remove residual oil, debris, and rust, ensuring the installation surface is flat and clean.
5. Store the removed old parts, bolts, nuts, etc., properly. Do not discard them carelessly to facilitate future recycling or comparison during installation.

3.4.2 Installing New Components

1. Ensure the installation orientation and angle of the new component match those of the old part. If the component has installation markings (e.g., "Front," "Rear," "Left," "Right"), strictly follow these markings during installation to prevent incorrect orientation.
2. Slowly position the new part into the mounting location. Adjust its placement to ensure a snug fit against the mounting bracket and surrounding components. Verify there is no looseness or misalignment, and prevent interference with other parts (e.g., for cable-type components, ensure cables move smoothly without kinks or snags; for brake components, ensure friction surfaces make proper contact).
3. Reinstall all fasteners (bolts, nuts, clips, etc.) in the reverse order of disassembly. Hand-tighten each connection until it is just loose. After confirming all connections are correctly installed, use tools to gradually tighten them to specification.
4. Exercise controlled force during tightening. Use a torque wrench to tighten to the manufacturer's specified torque (refer to the product specification sheet for exact values). Avoid over-tightening, which may damage threads, fittings, or motorcycle components. Similarly, insufficient tightening may cause loosening and compromise safety.
5. If fittings include accessories (e.g., seals, gaskets), ensure these are properly seated. Seals must lie flat without distortion or damage to prevent leaks or loosening.
6. After installation, gently shake the component to verify secure mounting with no looseness or abnormal noises. For brake, steering, or transmission components, manually test flexibility to ensure smooth operation without binding or sticking.
