What are the reasons for the clutch not disengaging?
2 Answers
The reasons for the clutch not disengaging are: 1. Excessive free play in the clutch operating lever; 2. The clutch intermediate plate is too rough or distorted; 3. Uneven clutch spring force; 4. Deteriorated engine oil with excessive viscosity or too high oil level; 5. The clutch housing is stuck on the transmission main shaft; 6. Failure of the clutch release mechanism. The clutch is located in the flywheel housing between the engine and the transmission. The clutch assembly is fixed to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the transmission. During driving, the driver can depress or release the clutch pedal as needed to temporarily separate or gradually engage the engine and transmission, thereby cutting off or transmitting the power input from the engine to the transmission.
I've encountered the issue of the clutch not disengaging several times, which is mainly due to some mechanical component problems. The most common possible cause is severe wear of the clutch disc. Over time, it wears down like sandpaper, and once it becomes too thin, it tends to get stuck and won't disengage. Additionally, there could be issues with the clutch pressure plate. If it's warped or cracked, the uneven pressure prevents proper release. The release bearing also needs checking—this part is located inside a small housing, and if it's aged or rusted solid, it directly hinders the disengagement action. For hydraulic clutches, the hydraulic system should be inspected—low fluid levels or air bubbles can make the pedal feel soft and unresponsive. Operational errors might also lead to this, such as not fully depressing the pedal when parking, which accelerates wear over time. It's advisable not to attempt DIY repairs; take the car to a repair shop for inspection. Safety first—don't let a small issue turn into a major problem by delaying.
