OEM Part Number 0JY0-051002
Drive Pulley Spring / CVT Spring
0JY0-051002
Type: CVT Drivetrain Component | Location: Inside Drive Pulley
OEM CVT spring · Determines shift characteristics · Affects acceleration and power delivery
This is a genuine CFMoto Drive Pulley Spring, part number 0JY0-051002. This spring is located inside the drive pulley of the CVT transmission and works in conjunction with the rollers. It controls the clamping force and shift timing of the pulley, directly influencing the vehicle's acceleration characteristics, transmission efficiency, and top speed. Directly replace a worn, fatigued, or broken spring to restore proper CVT shifting behavior and improve the riding experience.
✨ Product Location: Inside the CVT transmission, mounted between the movable and fixed faces of the drive pulley (primary sheave).
This drive pulley spring (0JY0-051002) is compatible with the following CFMoto models:

🔧 Importance of the Drive Pulley Spring
In a CVT system, the drive pulley spring works together with the rollers to determine the transmission's response characteristics. Over time, the spring can weaken due to metal fatigue, leading to sluggish acceleration, take-off shudder, or abnormal RPM behavior. Timely replacement of a worn drive pulley spring is an effective way to restore CVT performance and maintain the vehicle's power delivery.
