Pressure plate faults are usually accompanied by the following symptoms, and it is necessary to confirm whether replacement is required through comprehensive detection:

Abnormal driving experience
Starting shake: When shifting into first gear and slowly releasing the clutch, if the vehicle moves forward or backward or the body shakes, it indicates that the contact between the pressure plate and the friction plate is unstable.
Insufficient power: When accelerating sharply, the engine speed surges but the vehicle speed lags behind, or when climbing a slope, you need to press the accelerator deeply to maintain speed, indicating that the pressure on the pressure plate is insufficient.
Heavy clutch: When the clutch pedal is pressed, the resistance feels increased, which may be due to fatigue or deformation of the pressure plate spring, making it difficult to disengage.
Physical detection method
Visual inspection: After disassembly, observe whether there are cracks, burnings or grooves on the working surface of the pressure plate. If the depth of the groove exceeds 0.3 millimeters, replacement is required.
- Flatness measurement: Place the pressure plate on the flat plate and use a feeler gauge to check the gap. If the flatness error exceeds 0.5 millimeters, it indicates that the pressure plate has deformed.
Spring inspection: Check if the diaphragm spring is broken, burned or cracked. When the wear depth at the end of the separation finger exceeds 0.6 millimeters, it needs to be replaced.
Associated component status
If slippage still occurs after replacing the friction plate, it may be due to insufficient elasticity of the pressure plate spring, resulting in insufficient pressure.
When there are cracks or deformations in the clutch cover, the pressure plate and the clutch cover need to be replaced simultaneously.
