(1) When the car starts, the clutch pedal is depressed and the free stroke is exceeded, but it is still difficult to shift gears; if it is forced into gears, but the clutch pedal has not been fully lifted, the car will move forward or backward and cause the engine Turn off the fire.

　　(2) It is difficult to shift gears during driving, or the gears cannot be engaged, and the gear clashing in the transmission occurs.

　　The main reasons for incomplete clutch separation are:

　　①The free stroke of the clutch pedal is too large;

　　②The inner end of the separation lever is not on the same plane, and the individual separation levers are deformed, broken, and worn seriously;

　　③The clutch driven disc is warped, the rivet is loose, or the new clutch friction plate is too thick;

　　④The front and back of the clutch driven disc are installed in reverse;

　　⑤The clearance between the keyway of the driven disc hub and the spline tooth of the first shaft of the transmission is too small or jammed, causing difficulty in movement.

　　The diagnosis method for this kind of failure is: drive the car to a flat road, place the gear lever in the neutral position, and depress the clutch pedal. If there is only the driver, you can use a wooden stick to press down the clutch pedal and push it down. Hold (pull up the brake handle to make the hand brake work). In the hole under the flywheel housing, use a screwdriver to push the clutch plate. If you can push it gently, it means that the clutch can still be cut off. If you can’t push it, it means that the clutch cannot be separated.

　　The main reason for poor clutch separation is that the free stroke of the clutch pedal is too large. Furthermore, after replacing the clutch driven disc, the cleaning of the first shaft of the transmission was neglected and there were impurities, which caused the clearance between the driven disc hub and the first shaft to be too small, the moving resistance was large, and the clutch was not separated well. When purchasing the clutch driven plate assembly, the user should check for warpage and its thickness should meet the standard. If it is warped or too thick, it should be replaced.
