What Causes the Abnormal Noise When Depressing the Clutch?

[Ellis]

The reasons for abnormal noise when depressing the clutch are: 1. Worn clutch disc; 2. Broken clutch pressure plate spring; 3. Loose release bearing; 4. Lack of lubricant. The solutions for abnormal noise when depressing the clutch are: 1. Replace the clutch disc; 2. Replace the clutch pressure plate spring; 3. Adjust the release bearing; 4. Replenish lubricant. The working principle of the clutch is: 1. When starting the vehicle, the driver depresses the clutch, causing the pressure plate to separate from the friction disc, at which point the pressure plate and flywheel are completely disengaged; 2. During normal driving, the pressure plate is tightly pressed against the flywheel's friction disc, creating significant friction between them, maintaining relative static friction between the input and output shafts, resulting in identical rotational speeds.
