How It Works
The drive belt runs between the primary (drive) clutch and secondary (driven) clutch. As engine speed changes, the clutches adjust the belt's effective diameter, providing seamless gear ratio changes without a conventional gearbox. This continuously variable transmission (CVT) design allows the engine to operate at its most efficient RPM.
Common Failure Symptoms
A worn or damaged belt may cause slipping, loss of power, belt squeal, fraying, or cracking. Symptoms include poor acceleration, sluggish climbing, overheating of the CVT system, or a complete loss of drive. Regular inspection for glazing, cracks, or uneven wear is recommended.
Installation Notes
Installation requires removing the CVT cover and may involve loosening the clutch assembly. The belt must be seated correctly on both pulleys with proper tension. Always follow the factory service manual for your specific model. Using an OEM or high-quality replacement ensures correct fit and durability.
