What Causes Incomplete Clutch Disengagement?

[MacAriana]

Incomplete clutch disengagement is a behavior that causes severe wear to vehicles, with specific manifestations and causes as follows: 1. There are two phenomena of incomplete clutch disengagement: (1) When starting the car, the clutch pedal is pressed down beyond the free travel, but gear shifting still feels difficult; if forced into gear, the car moves forward or backward before fully releasing the clutch pedal, causing the engine to stall. (2) Difficulty in shifting gears while driving, or inability to engage gears, accompanied by gear collision noises inside the transmission. 2. The main causes of 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 individual levers deformed, broken, or severely worn; (3) Warped clutch driven plate, loose rivets, or newly replaced clutch friction plates that are too thick; (4) Incorrect installation of the clutch driven plate (front or back side reversed); (5) The keyway of the driven plate hub and the spline teeth of the transmission's first shaft have too small a gap or are stuck, making movement difficult.
