1. Platen. 2. Friction disc. 3. The separation bearing (also called the guide bearing) should be replaced at the same time when the 3-piece clutch is replaced, even if the other two pieces are not seriously worn. Because it is very troublesome to lift the gearbox to replace the three-piece clutch set, the labor cost is also high, and sometimes the accessories are not valuable, but the labor is expensive, so it is more cost-effective to replace the ring together than to separate the ring, and it also avoids the repeated disassembly and assembly of the machine. Yep.
Symptoms of a broken clutch three-piece
1. Clutch slips. When the car starts in a low-speed gear, after releasing the clutch pedal, the car cannot start or it is difficult to start; when the car accelerates, the speed of the car cannot be increased with the increase of the engine speed, and it feels powerless to drive, and in severe cases, it produces a burning smell or smoke. .
2. The clutch separation is not complete. When the engine is idling, the clutch can only be disengaged when the clutch pedal is almost bottomed out. Depressing the clutch pedal, you feel difficulty in shifting or the transmission gear makes a harsh slam, or the vehicle starts driving without lifting the clutch pedal after shifting, which indicates that the clutch of the vehicle is not completely disengaged.
3. Clutch noise. After stepping on the clutch pedal, the car clutch will make an abnormal sound when it is disengaged or engaged. If there is a "sand" sound after stepping on it lightly, it means the bearing has abnormal sound; The sound of collision indicates that there is movement before and after the release bearing.
