Causes and diagnosis of incomplete clutch friction plate separation
When the engine is idling, the sound of the gear is difficult to hang on the clutch friction plate pedal. If you are unwilling to hang up, completely shut down the engine when the clutch friction plate pedal is not fully relaxed.
Reason: The free stroke of the clutch friction plate pedal is too large, making it difficult to adjust the inner height of the release lever. The separation lever is improperly adjusted so that the inner end is in the same plane or the inner end is not too low; in individuals with improper adjustment of the limit screw of the dual clutch friction plate pressure plate, the separation spring is fatigued or broken, the height is insufficient, and the transmission pin or axial movement The clutch friction plate drive window is inflexible and the pressure center plate is inflexible; the driven plate is warped, the friction plate is cracked or the rivets are loose; the new friction plate is too thick or the drive plate is wrong; the small hole in the spline and the no. One shaft; the hydraulic control mechanism of the clutch friction plate is leaking, there is insufficient air or oil. The elastic force of the diaphragm spring is weakened, and the engine support is worn or damaged. The engine crankshaft and the transmission input shaft are not aligned.
Diagnosis and troubleshooting: Check the pedal free travel of the clutch friction plate. If the free travel is excessive, check the oil storage tank for insufficient hydraulic operating mechanism or air in the pipeline and perform necessary elimination; check the height of the inner end of the friction plate separation lever. The low friction plate release lever or not on the same plane, adjust, or check the top of the drive plate, if there is no problem, continue to check; check whether the moving plate is twisted and deformed, the rivets are falling off, and whether the driven plate axial moving box is replaced or repaired .
