What are the four causes of clutch slippage?
2 Answers
Here is a detailed introduction to the causes of clutch slippage: No free travel: The clutch pedal has too little or no free travel, causing the release bearing to constantly press against the release lever. Oil contamination on the driven plate: This reduces the frictional force on the surface of the driven plate. Severe wear: The friction lining of the driven plate, the pressure plate, or the working surface of the flywheel is severely worn, or the connection between the clutch cover and the flywheel is loose, reducing the clamping force. Driven plate failure: The friction lining of the driven plate is contaminated with oil, burnt, surface hardened, has exposed rivets, or is uneven, reducing the frictional force. Weak or broken pressure springs, or weak or cracked diaphragm springs, reduce the clamping force.
Four major causes of clutch slippage, which I've frequently encountered after years of driving. First, excessive wear of the clutch disc – over time, the disc becomes thinner, leading to insufficient friction, resulting in slow acceleration and jerky movements. Second, oil contamination – when oil drips onto the disc surface during repairs, causing slippage, especially noticeable in rainy weather. Third, improper adjustment, such as a loose clutch cable or incorrect pedal height, affecting transmission efficiency. Fourth, issues with the hydraulic system, like hydraulic fluid leakage or pump failure, commonly seen in modern vehicles. I recommend checking the clutch disc thickness during regular maintenance to detect and replace it early, avoiding breakdowns on long trips. If you experience difficulty shifting gears or weak acceleration during daily driving, stop and check immediately; don't push it. Severe clutch slippage can damage the flywheel, and repairs can be costly – safety first.
