The clutch does not disengage completely.

Release Date: 2014-11-25

Summary: Incomplete clutch disengagement manifests in the following two ways: (1) When starting the vehicle, even after depressing the clutch pedal beyond its free play, shifting gears remains difficult. If you force a gear into place before fully releasing the clutch pedal, the vehicle may lurch forward or backward, causing the engine to stall. (2) During driving, gear changes are hard to execute or impossible, accompanied by clashing noises from the transmission gears. The primary causes of incomplete clutch disengagement include: ① Excessive free play in the clutch pedal; ② Misalignment of the inner ends of the release levers—individual levers may be deformed, broken, or severely worn; ③ The clutch…

　　Incomplete clutch disengagement manifests in the following two ways:
　　(1) When starting the vehicle, depressing the clutch pedal beyond the free play still results in difficulty engaging a gear. If you attempt to force the gear into place but have not yet fully released the clutch pedal, the car may lurch forward or backward, causing the engine to stall.
　　(2) Difficulty shifting gears while driving, or failure to engage a gear, accompanied by gear‑clashing noises within the transmission.
　　The main causes of incomplete clutch disengagement are:
　　① The clutch pedal free play is too large;
　　② The inner ends of the release levers are not in the same plane; some release levers are deformed, fractured, or severely worn.
　　③ The clutch driven plate is warped, the rivets have come loose, or the replacement clutch friction plates are excessively thick.
　　④ The clutch driven plate has been installed with the wrong side facing outward.
　　⑤ The keyway in the driven‑disc hub and the spline teeth on the transmission’s first shaft have too little clearance or are seized, making shifting difficult.
　　The diagnostic procedure for this type of malfunction is as follows: Drive the vehicle onto a level surface, place the gearshift in neutral, and depress the clutch pedal. If only the driver is present, use a wooden rod to hold down the clutch pedal and keep it depressed (while simultaneously pulling up the handbrake lever to engage the parking brake). Then, insert a screwdriver into the opening beneath the flywheel housing and gently push on the clutch disc. If you can move it with ease, the clutch is still able to disengage; if it cannot be moved, the clutch is unable to fully disengage.
　　The primary cause of poor clutch disengagement is excessive free play in the clutch pedal. Additionally, after replacing the clutch driven disc, failure to clean the transmission’s input shaft can introduce contaminants, resulting in an overly tight fit between the driven‑disc hub and the input shaft. This increases friction and resistance to movement, leading to inadequate clutch disengagement. When purchasing a clutch driven‑disc assembly, users should inspect it for warping and verify that its thickness conforms to specifications; if warped or excessively thick, it must be replaced.
