What is the reason for the clutch not retracting and unable to shift gears?
2 Answers
The reasons for the clutch not retracting and unable to shift gears are: 1. Air entering the clutch pipeline system; 2. Dirty clutch fluid with impurities causing severe internal wear of the clutch master cylinder or blockage of the return oil hole; 3. Insufficient or broken clutch return spring tension; 4. Excessive wear gap of the clutch linkage push rod. Precautions for clutch use are: 1. The clutch must be thoroughly cleaned before installation to remove anti-rust grease and debris; 2. The clutch can be installed coaxially or on separate shafts, and must be fixed axially; 3. When a wet electromagnetic clutch is working, lubricating oil must be added between the friction plates; 4. For the power supply and control circuit, the clutch power supply is DC 24 volts; 5. When installing a jaw-type electromagnetic clutch, a certain gap must be ensured between the end face teeth to prevent grinding during idling.
I've encountered the issue of the clutch not springing back and being unable to shift gears several times myself, and it feels quite tricky. The main reasons could be a leaking clutch master or slave cylinder, causing insufficient pressure in the hydraulic system, so the spring can't pull it back after being depressed. Or the cable (if it's an older model) might be rusted and stuck, especially prone in humid weather. Additionally, a failed release bearing can cause the clutch to stick and fail to disengage properly. Sometimes, a broken pedal spring can directly lead to weak return. If this happens suddenly on the road, for safety, don't force a gear shift; immediately turn on hazard lights, pull over, and check for oil leaks or unusual noises near the pedal. In most cases, taking it to a repair shop where they can simply bleed the system and replace the fluid will fix it—don't tinker yourself to avoid damaging more components, as driving safety comes first.
