• Noise or vibration caused by an aged CVT belt
• Reduced performance from a belt that no longer holds proper tension

Installation Notes and Tips

Confirm the belt dimensions, section, and transmission specification before installation. Match the outside circumference and top width to the original belt requirements, and inspect the CVT pulleys for wear, glazing, or contamination before fitting the new belt. Proper belt alignment and clean pulley surfaces help maintain consistent operation after replacement.
