What are the symptoms of clutch slipping failure?

[VanNoah]

The symptoms of clutch slipping failure: 1. When starting the car, completely releasing the clutch pedal does not allow the car to start or makes starting difficult; 2. During acceleration while driving, the vehicle speed does not increase with the rise in engine RPM, and the engine's power is not fully transmitted to the drive wheels, resulting in weak driving force; 3. When fully loaded and going uphill, the slipping is more obvious, and in severe cases, a burning smell from overheating friction linings may occur. Causes of clutch slipping: 1. The clutch pedal free play is too small or nonexistent, causing the release bearing to frequently press against the diaphragm spring, keeping the pressure plate in a semi-engaged state; 2. Reduced elasticity of the diaphragm spring; 3. Excessive wear or hardening of the friction disc, contamination with oil, or exposed rivets; 4. Loose connecting bolts between the clutch and flywheel; 5. Improper adjustment of the release levers.
