What is the cause of clutch pedal jitter?

Cause of failure 1) The rear end face of the inner end of the separation lever is not in the same plane, the compression spring is uneven or broken individually, and the pressure plate has grooves.

2) The pressure plate and the driven plate are warped and deformed, the rivets of the friction plate are exposed, the surface of the friction plate is oiled, and the spline groove of the driven plate and the first shaft spline tooth of the transmission are seriously worn.

3) Loose fixing bolts of the engine suspension, transmission and flywheel housing, clutch cover, flywheel, etc., will cause the clutch to tremble at the start of the car.

Fault judgment and troubleshooting.

The engine is running rapidly, hang a low gear, and then slowly lift the clutch pedal to start, if the car shakes, it is the clutch shuddering.

1) Step on and lift the clutch pedal, check whether the separating bearing is flexible in advance and retreat, if it is astringent, it means that there is oil between the separating bearing and the conduit, and it should be cleaned.

2) Check whether the inner end of the separation lever is in the same plane, if not, it should be adjusted according to the regulations.

3) Check the fastening of the connecting bolts of each part, if there is any looseness, it should be tightened according to the specified torque.

4) Check whether the main and driven disc are warped and deformed, the friction surface is grooved and the friction plate rivet is exposed, if so, it should be repaired. Spring breaks should be replaced, and uneven elasticity should be arranged or replaced symmetrically.

Failure of the clutch or failure of the clutch release bearing or fork. It is advisable to check this section.

It is advisable to check whether the fixing screws at the connection under the lower clutch pedal are loose, which is generally the case.

Reasons for clutch pedal looseness:

1. The separation bearing is worn or stuck; Separation lever pins and pin holes are loose due to wear; The transmission pin and pin hole are loose due to wear.

2. When judging the clutch sound, you should step on the clutch pedal lightly, so that the release bearing is in contact with the release lever, and the sound heard at this time is the sound of the separation bearing, which may be caused by the lack of oil in the bearing or the loose damage of the bearing.

3. Continuously step on and relax the clutch pedal, and the clutch sounds when it is engaged or separated, which can be judged according to the severity of the sound, which is due to the loose wear of the separation lever pin hole and the supporting pin, or the loosening of the rivet of the driven disc assembly, and the failure of the shock absorber.

4. After stepping and relaxing the clutch pedal, and then stepping on the accelerator pedal, if there is an intermittent collision soundcode, it is the failure or break of the return spring of the disconnecting bearing.

5. When the double-plate clutch steps on the bottom of the pedal to the bottom of the clutch, it makes a "click, click" sound, which is caused by excessive wear and tear between the middle pressure plate hole and the transmission pin.

The reasons for the shaking of the pedal of the clutch shirt are as follows: 1. It may be that the pressure distribution of the clutch of the car is uneven, or the spring is loose or disconnected, and the pressure level is wrong, so the clutch is unstable; 2. It may be that the clutch compression spring is too large, which causes or disturbs the trembling of the clutch; 3. The stagnation of parts such as the separation sleeve and the separation fork shaft, resulting in the clutch trembling; 4. It may be that the lining of the moving disc is oily or cracked, or the jitter caused by the thickness of the driven disc is different; 5. It may be the clutch shake caused by the bending of the main and slave disc and the inconsistent height of the separation lever; 6. Loose fixing bolts of engine suspension, transmission, flywheel housing, clutch cover, flywheel, etc., will cause the clutch to tremble at the start of the car.

Clutch pedal jitter can be caused by damage to the release bearing or excessive wear of the tension plate in the center of the platen. 1.The release bearing is in direct contact with the pressure plate, and if the release bearing is stuck, the pedal will shake when the clutch is pressed, and only by replacing the release bearing can the problem be completely solved.

Replace the separation bearing to disassemble the gearbox down, must always touch the cherry to check the shrapnel of the platen, if the pressure plate is seriously rusted or worn, the pressure plate must also be replaced, otherwise it can not completely solve the problem. 2.Clutch pedal jitter is the most tolerant of the clutch in the cable type clutch is easy to appear, because the tension of the cable adjustment leads to the direct connection between the release bearing and the pressure plate, if it is a hydraulic clutch, when the clutch is not stepped on, the release bearing and the pressure plate will maintain a certain clearance to prevent the release bearing from rotating.

The cause of clutch pedal jitter: damage to the release bearing, excessive wear of the pressure plate. 1.

If the pedal shakes when he presses the clutch pedal after Qisun attacks the vehicle, it means that the release bearing is damaged, or the surface of the pressure plate is abnormally worn. It can only be solved by replacing the corresponding accessories. For example, if the release bearing is damaged, replace the release bearing, and replace the pressure plate in time if the wear of the pressure plate is too large.

2.The reason for the damage of the separation bearing is the lack of grease lubrication inside the separation bearing, or the separation bearing has been in contact with the pressure plate. After starting the vehicle, the pressure plate has been rotating, if the release bearing has been in contact with the pressure plate, it will cause the release bearing to rotate all the time, and the long-term rotation will cause the separation bearing to heat up, and the internal butter will liquefy and flow out, and finally cause damage due to lack of grease lubrication.

Generally, if the separation bearing is damaged and not repaired in time, it will lead to excessive wear of the pressure plate, and eventually lead to the clutch plate not being separated.

Common points of failure for clutch pedal shake:

It may be caused by a malfunction of the disengagement bearing in the vehicle's clutch system.

It may be caused by a malfunction of the clutch plates in the vehicle's clutch system.

It may be caused by a malfunction of the clutch pressure plate in the vehicle's clutch system.

This may be caused by a malfunction of the clutch pedal in the vehicle's clutch system.

The specific construction and sale collapse is exhausted, and the dry circle is quickly checked for defeat and loss.

The reasons for the jitter of the clutch pedal are: 1. The rear end face of the inner end of the separation lever is not in the same plane, the compression spring is uneven or broken individually, and the pressure plate has grooves; 2) The pressure plate and the driven plate are warped and deformed, the rivets of the friction plate are exposed, the surface of the friction plate is oiled, and the spline groove of the driven plate and the first shaft spline tooth of the transmission are seriously worn. 3) Loose fixing bolts of the engine suspension, transmission and flywheel housing, clutch cover, flywheel, etc., will cause the clutch to tremble at the start of the car. 4. The positive pressure distribution between the main and slave discs is uneven. Often the uneven elasticity of the compression spring of the engagement clutch, the inconsistent adjustment of each separation lever or the uneven finger end of the diaphragm spring separation will make the compression time inconsistent, the pressure plate will be unevenly stressed, and even the pressure plate will be skewed, resulting in poor contact between the main and driven discs, causing the clutch to shake.

1.This may be caused by uneven clutch pressure distribution.

2.It may be caused by the excessive elasticity of the clutch spring.

3.The main and slave disc is bent, and the disconnect lever is inconsistent, causing the clutch to tremble.

4.It is also possible that the lining of the driven disc is oily or cracked, or the thickness of the driven disc is different and causes jitter. It depends on what the reason is, and this has to be dismantled to see what the reason is! It is recommended to go to the repair shop to check, I hope it can help you.

If the clutch pedal shakes, it means that there is a problem or fault inside the clutch, and you need to ask professional maintenance personnel to repair and solve it.

The clutch is worn, but changing the clutch is always better.
