According to the vehicle conditions, this type of fault is mostly caused by excessive sludge in the clutch release bearing bushing, poor return, or a broken clutch pedal. The repair method for this situation is to disassemble and clean the transmission. Reasons for the clutch not rebounding: Air mixed into the clutch pipeline system; Clutch fluid is too dirty with impurities, causing severe internal wear of the clutch master cylinder or blockage of the return oil hole; Insufficient or broken clutch return spring tension; Excessive wear gap in the clutch linkage push rod. Precautions for clutch use: The clutch must be cleaned thoroughly before installation to remove anti-rust grease and debris; The clutch can be installed coaxially or on separate shafts, but axial fixation is mandatory; When the wet electromagnetic clutch is working, lubricating oil must be added between the friction plates; The power supply and control circuit, the clutch power supply is DC 24 volts; When installing the jaw-type electromagnetic clutch, a certain gap must be ensured between the end face teeth to prevent gear grinding during idling.
