This product is a genuine quality Hisun CVT Wet Clutch Cover One Way Bearing, part number 21220-004-0000 / 21220-f39-0000. This one way bearing (also known as overrunning clutch) is installed inside the CVT wet clutch cover and is a critical component of the CVT transmission system. It allows power transmission in one direction while freewheeling (overrunning) in the opposite direction, ensuring proper CVT operation for smooth starting and seamless shifting.
Over time, the one way bearing may experience needle wear, spring failure, or seizing, leading to clutch slippage, noise, or hesitation during startup. Timely replacement of a damaged one way bearing is essential for restoring CVT performance and driving experience.
🔧 Genuine Quality Assurance: Manufactured strictly according to Hisun OEM technical standards using high-strength steel and precision bearings. Dimensions, hardness, and assembly precision are identical to the original parts, ensuring perfect replacement and reliable durability.
