Always verify the belt dimensions and model compatibility with your scooter's service manual before installation.
3. Installation Guidelines
Installation of a CVT belt requires specific tools and mechanical knowledge. It is highly recommended that installation be performed by a qualified technician or an experienced individual following the scooter's official service manual.
General Steps (Consult your scooter's service manual for detailed instructions):
- Ensure the scooter is on a stable stand and the engine is off and cool.
- Remove the CVT cover to access the variator and clutch assemblies.
- Carefully remove the old belt, noting its orientation.
- Clean any dust or debris from the variator and clutch pulleys.
- Install the new Bando CVT Belt, ensuring it is correctly seated on both pulleys. Pay attention to any directional arrows on the belt.
- Reassemble the CVT cover, ensuring all fasteners are tightened to the manufacturer's specifications.
- After installation, perform a test ride at low speeds to confirm proper operation before full use.

4. Operating Considerations
The CVT belt is designed to provide smooth and continuous power delivery. After installation, allow for a brief break-in period (typically 50-100 miles) where aggressive acceleration and high speeds are avoided. This helps the belt seat properly within the variator and clutch pulleys, optimizing its lifespan and performance.
5. Maintenance
Regular inspection and timely replacement are crucial for the longevity and performance of your scooter's CVT system.
- Inspection: Periodically inspect the belt for signs of wear, cracking, fraying, or glazing. Refer to your scooter's service manual for recommended inspection intervals.
- Cleaning: Keep the CVT area clean and free of dust, oil, and debris. Contaminants can reduce belt life and efficiency.
- Replacement: Replace the belt according to the manufacturer's recommended service schedule, or sooner if signs of excessive wear are observed. A worn belt can lead to reduced performance, slippage, and potential damage to other CVT components.
6. Troubleshooting Common Issues
If you experience issues with your scooter's drive system, consider the following common problems related to the CVT belt:
- Slipping or Loss of Power: This often indicates a worn or glazed belt, or contamination (oil/grease) on the belt or pulleys. Inspect and replace if necessary, and clean the CVT components.
- Unusual Noises (Squealing, Grinding): Can be caused by a worn belt, misaligned components, or foreign objects in the CVT housing. Disassemble and inspect the CVT system.
- Poor Acceleration or Top Speed: May suggest a worn belt that is not engaging properly, or worn variator rollers. Check belt condition and other CVT components.
- Vibration: Could be due to an unevenly worn belt or unbalanced CVT components.
For persistent issues, consult a professional mechanic.
