🔧 CVT Drive Belt · Transmission Belt · Gates Brand

Length 711mm · Width 18mm · Tooth Angle 30°

This is a high-quality CVT drive belt manufactured by Gates, a globally renowned brand in power transmission, with specifications 711 × 18 × 30. Gates belts are world-famous for their exceptional durability, stable performance, and precise dimensions, serving as original equipment for many scooter and ATV manufacturers.

Specification Explanation:

• 🔹 711 = Belt length in millimeters | 皮带长度 (毫米)
• 🔹 18 = Belt width in millimeters | 皮带宽度 (毫米)
• 🔹 30 = Belt tooth angle in degrees | 皮带齿形角度 (度)

This belt fits various scooter and ATV models, making it an ideal replacement for original belts.

This belt fits scooters and ATVs using CVT belts sized 711×18×30, including but not limited to:

• 50cc-150cc scooters
• GY6 engine scooters
• Some small ATV models
• Other vehicles using the same CVT belt specifications

The CVT (Continuously Variable Transmission) belt is the heart of your scooter or ATV's transmission system, with crucial functions:

• Power Transmission: Transfers engine power from the drive pulley to the driven pulley, ultimately driving the wheels.
• Variable Ratio: Provides seamless gear ratio changes as the belt moves between different pulley diameters, eliminating traditional shifting.
• Performance Impact: Belt quality directly affects acceleration response, top speed, and transmission efficiency.
• Safety & Reliability: Poor quality or worn belts can break, causing power loss and creating safety hazards.

• Poor Acceleration: Sluggish throttle response, noticeably slower acceleration.
• Jerky Takeoff: Vibration or shuddering when starting from a stop.
• Reduced Top Speed: Unable to reach normal maximum speed.
• Belt Slippage: Engine RPM increases rapidly during hard acceleration but vehicle speed doesn't match.
• Abnormal Noise: Rubbing, squealing, or other unusual sounds from the transmission case.
• Visible Wear: Upon inspection, belt shows reduced width, uneven side wear, or cracks.

If you experience these symptoms, inspect the CVT belt promptly and replace if necessary.

The 30° tooth angle is a critical parameter of CVT belts, referring to the angle between the belt side and the vertical. This angle must precisely match the pulley groove angle:

• Precise Matching: Only when the tooth angle matches the pulley groove angle will the belt have full contact with the pulley for maximum power transmission efficiency.
• Reduced Wear: Mismatched angles cause poor belt-to-pulley contact, accelerating belt wear and reducing service life.
• Prevents Slippage: Correct angle ensures the belt won't slip at high speeds, maintaining stable power delivery.
• Noise Reduction: Properly angled belts run quieter with less abnormal noise.

🔧 Installation Tip

1. Replacing a CVT belt requires removing the transmission cover. Professional installation or mechanical experience is recommended.
2. Clean the transmission housing before installation and inspect variator, driven pulley, and roller weights for wear.
3. Note belt orientation if directional (many are not), and ensure the belt is properly seated in the pulley grooves.
4. Check belt tension after installation to ensure it's within specifications.
5. After replacement, perform a short test ride to confirm normal transmission operation.
