Clutch overhaul? How do I change the clutch?

The clutch is dynamically balanced to ensure uniformity and prevent centrifugal force from shaking.

1. Clutch disc detection

Visual inspection. The appearance of the clutch driven disc should be free of obvious scratches, oil stains and damage. The rivets must not be exposed, the torsion damper springs must not be damaged or broken, and the spline drum must not be loose.

If there is oil on the driven disc, it means that the transmission oil seal may be leaking and should be inspected. If the driven disc is damaged or the fracture position is different, the driven disc should be replaced in time.

Rivet depth inspection. Check the rivet depth of the driven disc with a vernier caliper. The minimum depth between the upper surface of the rivet and the surface of the friction plate was selected for the test. When the rivet depth is less than and the friction disc reaches the limit of use, the driven disc assembly should be replaced.

Second, clutch pressure plate detection

Visual inspection. The clutch pressure plate should be free of ablation, visible scratches, damage, and breakage. When the above situation occurs, it should be replaced.

Clutch pressure plate flatness detection. Check the flatness of the platen with a feeler gauge and ruler. Place the vertical face of the ruler on the platen through the center of the platen and test it with a feeler gauge of millimeters.

The gap gauge fails, and the flatness of the pressing plate is qualified; Otherwise, the pressure plate is warped and should be replaced in time. Flatness inspection, which should be checked multiple times from different angles to ensure the accuracy of the inspection.

Clutch pressure plate wear and sag detection. Signs of wear can be seen by looking at it. Use vernier calipers to detect wear dents. The depth of the depression must not be exceeded. If it is exceeded, it should be replaced in time.

3. Diaphragm spring test

Check the wear width of the diaphragm spring. Vernier calipers are used to measure the wear width of the contact surface between the inner end of the diaphragm spring and the separating bearing. If the measured actual wear width is greater than 5mm, it means that the diaphragm spring is overwhelmed and should be replaced in time.

Check the inner end jaws of the diaphragm spring. Measure the distance of the diaphragm spring inner jaw from the plane with a vernier caliper. The height difference shall not be exceeded. If the deformation is too large, the diaphragm spring should be replaced in time.

Detection of diaphragm spring force. Use a special tool to test the diaphragm spring force. Due to the different models and standard values, the maintenance manual shall prevail. If the measured spring force is less than the standard value, the diaphragm spring should be replaced in time.

5. Inspection of the separation bearing.

The bearing separation inspection is mainly an inspection.

Fourth, the clutch hydraulic system exhaust.

The exhaust of the clutch system requires the cooperation of two people. One person repeatedly presses the clutch pedal in the car, and the other loosens the release screw at the clutch pump position. If there is foam oil or no oil flowing out, then there is air in the hydraulic system.

Tighten the release screw, press the clutch pedal repeatedly, and release the exhaust screw. until the liquid is spit out smoothly and uninterrupted. After exhausting, check the oil level in the tank and adjust the clutch pedal to normal.

During the exhaust process, check the hydraulic system for air leaks or air leaks. Or determine the extent and location of the leak depending on the state of the oil.

Stability of rotation and whether there is abnormal noise. When the separating bearing rotates, there should be no jamming and abnormal noise, otherwise it should be replaced.

First of all, from the appearance of the inspection, then rivet depth inspection, clutch pressure plate inspection, to observe whether there are obvious scratches, damage and breakage, you can check the problem.

It can be handed over to a professional person for maintenance, this kind of thing is more complicated, and ordinary people have no way to overhaul it well.

Drive the car directly to the repair shop, and then let some professional staff check the car, so that the clutch failure can be repaired.

1. First unscrew the fixing screw of the clutch pressure plate.

2. After the fixing screw of the clutch pressure plate is unscrewed, the entire clutch can be taken down.

3. Take off the clutch plate on the clutch.

4. Install the new clutch plate on the clutch.

5. Install the clutch back in place to complete the operation of the source.

Are you talking about how car clutches are replaced? The replacement of the clutch depends on the type of gearbox you have, if it is a manual gearbox, it is relatively simple, you only need to disconnect the lead mountain connection between the gearbox and the transmission shaft, and you can see the manual clutch to replace him in the whole set.

To disassemble the clutch, it can be replaced by disassembling it completely.

The reason for clutch overhaul is that the clutch is made up of friction materials, which can lead to wear and tear due to long-term use and friction. When the clutch plate and clutch pressure plate are worn to a certain extent, the hydraulic components in the clutch system have oil leakage problems, and the seals of the master cylinder, slave cylinder and connecting pipeline are damaged. An oil leak can cause the clutch to malfunction and need to be serviced.

There is a mismatch between the engine and transmission, and the clutch is subjected to additional stress, leading to wear failure. The failure of the clutch drive plate pressure plate also caused the clutch to fail.

The causes of clutch overhaul are wear, oil leakage, speed mismatch, drive plate, and pressure plate failure.

Clutch introduction.

The clutch is an important component in automobiles and other mechanical drivetrains, where it connects and dissolves the power transfer between the engine and the transmission. The working principle of the clutch is that when the driver presses the clutch pedal, the clutch master cylinder transmits the pressure through the connecting rod and rod, so that the release device exerts pressure on the pressure plate. This separates the pressure plate from the flywheel, disconnecting the engine from the transmission and shifting gears.

When the driver releases the clutch pedal, the release reduces the pressure of the bucket, allowing the pressure plate to re-engage with the flywheel and reconnect the engine to the transmission.

Hello pro-clutch overhaul and adjustment clutch main parts overhaul: driven disc (friction plate, clutch plate, face piece) overhaul (1) damage form: wear, ablation, cracking, oil stain, rivet loosening, and posture steel plate warping deformation.

Maintenance method: (2) Mild oil stain: visual inspection; Wash with gasoline and dry.

Slight hardening and ablation: Careful visual inspection of the shed; Sand with an abrasive cloth.

How to repair the clutch of the car:

1. Check whether the free stroke of the clutch pedal is too large and adjust;

2. Check whether the high disappearance of the separation lever is consistent and whether it is too low. Toggle the release fork under the car, so that the front end of the release bearing gently leans on the inner end of the release lever, rotate the clutch for a week to check, if the inner end of the release lever can not be in contact with the release bearing at the same time, the height of the release lever is inconsistent, and the balance should be adjusted. If the separation lever height is the same, but the separation is still incomplete, the lever height should be checked.

Adjust each separation lever to the same height, if it can be completely separated, it means that the original adjustment is not appropriate or too worn. After the disengagement lever is adjusted, the free stroke of the clutch pedal must be readjusted;

3. If the separation is still incomplete after the above adjustment is normal, the clutch should be removed, and the clutch should be checked to check whether the driven disc is reversed, whether the axial movement is difficult, whether the main and slave disc is warped, whether the separation lever screw is loose, and whether the floating pin falls off;

4. For the clutch of the newly riveted friction plate, check whether the driven disc and friction plate are too thick. If it is too thick, a gasket can be added between the clutch hall cover and the flywheel;

5. For the clutch of hydraulic transmission, in addition to the above inspection, it should also be checked whether the brake fluid is missing, whether the pipeline is leaking and the air in the hydraulic system should be discharged.
