Incomplete clutch disengagement is a behavior that causes severe wear to the car, with specific manifestations and causes as follows: 1. Incomplete clutch disengagement exhibits the following two phenomena: (1) When starting the car, pressing the clutch pedal beyond the free travel still results in difficulty shifting gears; if forced into gear, the car moves forward or backward before fully releasing the clutch pedal, causing the engine to stall. (2) Difficulty shifting gears while driving or inability to engage gears, accompanied by gear collision noises in the transmission. 2. The main reasons for incomplete clutch disengagement include: (1) Excessive free travel of the clutch pedal; (2) The inner ends of the release levers are not on the same plane, with some levers deformed, broken, or severely worn; (3) Warped clutch driven plate, loose rivets, or newly replaced clutch friction plates that are too thick; (4) The clutch driven plate is installed backward (front and back reversed); (5) The keyway of the driven plate hub and the spline teeth of the transmission's first shaft have insufficient clearance or are stuck, making movement difficult.
