When stepping down or relaxing the pedal, there is a "rustling" sound, and you should check whether there is a free stroke. If the abnormal noise disappears after adjusting the free stroke, the working condition of the release bearing can be further checked. If it is not serious, it can be continued to be used and replaced during maintenance.

When the pedal is lightly pressed (eliminating free stroke), there is a "rustling" sound, which is usually a damage to the release bearing. This is because the inner end of the diaphragm spring is in contact with the release bearing. If the disengaging bearing is in good condition, it should not be stepped down on the basis of the light pedal, if there is a similar collision, impact of the abnormal sound, usually caused by the clutch cover bolt loosening.

When the pedal is pressed to the bottom, there is an abnormal sound of "bang, bang", which means that the driven disc is damaged or the spline is worn.

When the car starts and the clutch is semi-disengaged, there is an abnormal sound, indicating that the driven disc shock absorbing spring is damaged or the driven disc hub rivet is loose.

After inspection, it was verified that the abnormal noise is most noticeable when the car starts. The clutch was dismantled and inspected, and it was found that two of the shock absorber springs of the driven disc were broken. Replace the clutch driven disc, and the abnormal noise disappears.

Driving safety has a lot to do with the clutch, if there is an abnormal noise, it is recommended to detect it as soon as possible.

This may be caused by a malfunction of the clutch's disengaging bearing, and when this happens, the clutch's disengaging bearing needs to be replaced. The clutch belongs to the transmission system of the car, and the clutch can be connected or disconnected from the engine and transmission, and the clutch is installed between the engine and the transmission.

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

There is this sound after the clutch is stepped on, and the sound is no longer after it is released, this is a problem with the clutch release bearing, and the clutch release bearing will rotate after the dry friction clutch is stepped on, and the clutch release bearing needs to be replaced.

Questions. Disconnect the bearing, the clutch plate pressure plate has been replaced or ringing.

Then you need to check the inside of the gearbox to check the bearing in the gearbox to see if there is any problem.

Questions. Which bearing?

Bearings inside the gearbox.

Questions. Isn't the clutch gearbox disengaged? Why is it a gearbox?

Although it is said to be separated, there is still a slight rotation in this gearbox.

Questions. It's not a thrust plate on the back of the engine.

This one is not, this thrust tablet doesn't make this sound.

Questions. Could it be something else?

There is also the need to check this clutch fork. It is to see if there is friction between this fork and this release bearing after releasing it.

Questions. Good.

The occurrence of this phenomenon is due to the slight wear and tear of the clutch pedal support shaft due to long-term use, and it is generally enough to apply some lubricant to the support shaft.

Hope it helps, hope!

This phenomenon is caused by the wear and tear of the clutch pedal support shaft due to long-term use, and it is generally enough to apply some lubricating oil to the support shaft. Or if the release shaft of the clutch fails, the clutch release bearing will be replaced. Personal insights!

This situation is likely to be caused by the lack of oil on the clutch pedal, you can oil the clutch pedal connection, if there is a clutch cable, you can fill the cable with oil.

Some vehicles always make a sound similar to "squeak" when pressing the clutch pedal, and many car owners will think that the clutch is faulty. This phenomenon occurs because the clutch pedal support shaft is slightly worn due to long-term use, which can be alleviated by applying some lubricant to the support shaft position.

1. Gently step on the clutch pedal, when the clutch release bearing and the release lever are in contact, there is an obvious "rustle" sound, which can be judged to be the clutch release bearing. In this case, the release bearing can be greased.

If it still rings after adding grease, it is the damage of the separating bearing, if the separating bearing has stagnation or the axial clearance is too large, the new bearing should be replaced. If the wear of the inner ring of the bearing is greater than that, and the entire bearing is idling on the separator sleeve, the bearing and the separating sleeve should be replaced.

2. Press the clutch pedal to make a "whoosh" metal friction sound. If there are ablation marks or sparks at the contact between the clutch release bearing and the release lever, it means that the clutch release bearing does not rotate or is damaged, and the bearing should be replaced.

3. When the engine is idling, the clutch has a "bang" sound, and the accelerator is stepped on slightly. There is no change in the sound, it may be caused by the breaking of the separation lever screw, and the damaged part should be replaced.

4. When the engine is idling, the clutch has a "gurgling" impact sound. The sound above medium speed weakens or disappears, and then step on it again.

When the clutch pedal is lowered, the sound also disappears, indicating that the clutch friction plate rivet is loose or the keyway of the driven disc is worn.

In this case, the bottom cover of the flywheel housing (or clutch chamber) can be removed, and when the engine is turned off, the transmission is put in upper gear, the clutch pedal is pressed, and the keyway is checked for clearance with the cone toggle disc. If the gap is large, it needs to be repaired or replaced with a new part.

5. If the clutch pedal is all lifted, there is noise or intermittent knocking sound. The reason for this may be that there is no clearance between the clutch release bearing and the release lever.

In this case, the free stroke of the clutch pedal is adjusted, i.e. there is no clearance between the release bearing and the release lever. It may also be that the return spring is soft, broken, elongated, falling off, etc., which causes the free sliding of the release bearing and the contact of the release lever, which should be repaired or replaced as appropriate. Notes:

1. The clutch must be cleaned before installation to remove anti-rust grease and debris.

2. The clutch can be installed coaxially or sub-shaft, the axial direction must be fixed, the active part and the driven part are not allowed to have axial channeling, and when the sub-shaft is installed, the coaxiality between the active part and the driven part of the shaft should not be greater.

3. When the wet electromagnetic clutch is working, lubricating oil must be added between the friction plates.

4. When the tooth-embedded electromagnetic clutch is installed, it must be ensured that there is a certain gap between the end teeth, so that there is no grinding phenomenon during idling, but it shall not be greater than the δ value.

5. The electromagnetic clutch and brake are Class B insulation, and the normal temperature rise is 40. The operating temperature at the ultimate thermal equilibrium is not allowed to overspeed by 100, otherwise the coil and the friction part are prone to damage.

6. Power supply and control circuit, clutch power supply is DC 24 volts (except for special orders). It is obtained by three-phase or single-phase AC voltage through step-down and full-wave rectification (or bridge rectification), and the unregulated voltage and flat-wave require sufficient power. Half-wave rectifier power supply is not allowed.

Learn to distinguish between abnormal noises that are reasonable sounds.

On the issue of abnormal noise of automobiles, it is difficult for ordinary car owners to distinguish which ones are abnormal noises and which ones are reasonable abnormal noises. Only nearly 20% of the vehicles that went to the repair shop to detect abnormal noises really had problems. In the case of a turbocharged engine, there is a must be a difference between the sound and the sound of a naturally aspirated engine; Models with engine guards may also make noises due to friction; After some car owners come into contact with different cars, it is likely that due to their lack of understanding of mechanical knowledge, they mistake reasonable abnormal noise as a vehicle failure.

Therefore, learn to distinguish the abnormal noise of the car and avoid wasting time and energy.

Second, the identification method of car noise:

In practice, due to the limitations of working conditions, it is difficult to measure the sound of the car with special instruments, and the sound of the car can only be described and compared with the judgment of the sound in daily life. For example, the "rattle" sound caused by the dry friction of the bearing, and the "click" sound similar to the small hammer hitting the cement floor caused by the excessive valve clearance.

1. Correctly distinguish between normal and abnormal sounds.

The vibration of each mechanism in the work of the car will emit a variety of sounds, but the sound does not mean that the car is faulty, in order to avoid unnecessary disassembly, we must first distinguish between normal sound and abnormal noise. The normal vibration sound of each system component (such as the noise on the surface of the engine), the impact sound of the gear when shifting, the air intake sound and exhaust sound of using gas as the working source, and the gear meshing noise are all normal sounds. Abnormal noise (abnormal noise) can be divided into slight noise, general noise and malignant noise according to the impact on the performance of the car.

Slight noise, such as the flashover sound of high-voltage electric leakage, the slight loose sound of rolling bearings, etc., the general volume is small, the degree of wear of the parts is not large, and there is no significant change for a long time, and this kind of fault can still maintain the normal operation of the car without repair.

3. When diagnosing abnormal noise, attention should be paid to creating good auscultation conditions and trying to eliminate the interference of other noises, so as not to affect the accuracy of judgment.

It is best to consciously amplify or reduce the sound, that is, use a screw or other metal rod as a stestological instrument to contact the sound part to amplify the sound, or use a single cylinder fire cut-off to reduce the sound to meet the diagnostic needs. The auscultation site should be kept quiet to minimize human interference.

There are generally two reasons for this, one is caused by mechanical failure, such as a paralysis of the clutch pressure plate or a loose release bearing. There is also a kind of wear and tear caused by parts, such as severe wear of clutch wear plates.

There is a rustling sound when stepping on the clutch, which is generally the cause of the failure of the clutch, and the clutch is slipping or aging, which will make this sound.

The reasons for the abnormal sound when stepping on the clutch are: 1. The clutch plate is worn; 2. The clutch pressure plate spring is broken; 3. The separation bearing is loose; 4. Lack of lubricant. The solution to the abnormal sound of stepping on the clutch is:

1. Replace the clutch plate; 2. Replace the clutch pressure plate spring; 3. Adjust the separation bearing; 4. Replenish lubricants. The working principle of the clutch is: 1. When the vehicle starts, the driver steps on the clutch, the pressure plate is separated from the friction plate, and the pressure plate and the flywheel are not in contact at all; 2. When the vehicle is running normally, the pressure plate is tightly squeezed on the friction plate of the flywheel, and the friction between the pressure plate and the friction plate is larger, and the relative static friction is maintained between the input shaft and the output shaft, and the speed of the two is the same.

This hall is likely to be a fault phenomenon is likely to be the clutch pedal back to pop out of the abnormal sound, you can first use lubricating oil to lubricate the auspicious bureau hidden, if there is still an abnormal sound, you need to replace the clutch pedal assembly.

In addition, when stepping on the clutch pedal, you can clearly hear the clutch part of the abnormal sound, when the moment of relaxing the pedal is more obvious, this fault phenomenon is very local chain may be the clutch pedal back to pop out of the abnormal sound, you can use lubricating oil lubrication first, if there is still abnormal noise, you need to replace the clutch pedal assembly. In addition, when stepping on the clutch pedal, you can clearly hear the abnormal sound of the clutch step, and the moment when the pedal is relaxed, it is more obvious, and the main reasons for this situation are: the clutch pressure plate spring is broken or the separation bearing is loose, the clutch steel plate is broken, the clutch separation lever folding stool is guessed, the wear is excessive or the separation lever adjustment bolt is broken.

Solution: 1. Replace and repair the separation bearing, which has too much resistance due to serious wear and lack of oil.

2. Replace and repair the clutch plate, the clutch plate is seriously worn, resulting in unclear fit.

Bi Zaofeng 3. Replace and repair the wire sleeve, the lack of oil or damage to the wire sleeve leads to high resistance.

The clutch is a common component in mechanical transmission, which can be disengaged or engaged at any time by the drive train system.
