Product Details

The Gates G-Force Carbon Cord CVT Belt line was developed around carbon cord reinforcement to improve tensile stability under load. On this 40C4340 belt, the carbon cords are paired with a specially formulated adhesion compound to help reduce edge cord pullout and support longer service life. The result is a CVT belt built for automatic transmission systems that need consistent engagement and dependable power transfer.

This part cross-references Dayco HPX5009 and XTX5033 for the same application. If you are replacing a worn CVT belt on a Yamaha or Honda power sport machine, the Gates 40C4340 offers an OE-style replacement path with upgraded belt construction.

What This Belt Helps Address

• Belt slip under acceleration
• Loss of drive response from belt wear
• Edge fraying or cord pullout
• Inconsistent CVT engagement
• Reduced belt life from heat and load cycling

Installation Notes

Verify the belt size, section, and outside circumference before installation. Confirm the CVT system specification for your vehicle and inspect pulleys, clutch faces, and belt alignment at the same time. For fitment-based searches, this part is commonly sought for Yamaha and Honda CVT belt replacement applications, including power sport models that use the RVS-R section and 35 mm top width.

Use the exact part number 40C4340 when matching replacement belts, and compare the old belt dimensions to the listed 44.625-inch outside circumference and 1.375-inch top width.

Quality Assurance

Gates is known for drivetrain and power transmission components, and the G-Force Carbon Cord CVT Belt line uses carbon tensile cord technology with reinforced rubber construction to support consistent performance in CVT systems.
