I. Definition of release bearing

Release bearing, also known as ‘clutch throwout bearing’, usually refers to the bearing used in automobile manual gearbox, which is installed between the clutch and transmission. Its main function is to separate the clutch disc from the flywheel when shifting gears, thus enabling switching between different gears. The release bearing is located between the clutch pressure plate and the input shaft of the transmission. When the driver depresses the clutch pedal, the release bearing will be pushed, which makes the clutch pressure plate release the pressure on the clutch disc, and the clutch disc separates from the flywheel, thus interrupting the power transmission.

Second, whether the release bearing noise can drive

If the release bearing is noisy, it may be worn, seized or poorly lubricated, which can have a significant impact on the normal operation of the car. The noise will not only reduce the driving experience, but may also indicate that there is a serious problem with the bearing, which in turn affects the stability of power transmission and even jeopardises driving safety. However, continuing to drive may aggravate the problem and even lead to more serious gearbox failures. Therefore, it is not recommended to continue driving when the release bearing is noisy.

If the separation bearing noise, although the short-term may not immediately lead to the vehicle can not drive therefore, it is recommended not to ignore the problem, should be checked and repaired as soon as possible.

Third, the solution to the separation bearing noise problem

Lubrication:

Check the lubrication of the separation bearing. If the grease is insufficient or deteriorated, it should be supplemented or replaced with new grease. For different types of separation bearings, the lubrication may be different.

Inspection and Replacement:

Fix the inner ring of the separation bearing by hand and rotate the outer ring while applying pressure in the axial direction to check whether there is any blockage or obvious gap feeling. If so, the separation bearing should be replaced with a new one.

When disassembling and inspecting the separation bearing, the separation lever fixing screws and bolts should be screwed down from the transmission case, the separation lever removed, the separation bearing assembly and fixing spring removed, and then the separation bearing pulled off the separation bearing seat with a puller for inspection.

REPLACING THE SEPARATION BEARING: Due to the construction of the separation bearing and the environment in which it operates, the most complete solution in the event of noticeable noise is to replace the separation bearing with a new one. This usually involves separating the gearbox from the engine and is a relatively complex repair process, and is recommended to be carried out by a professional mechanic.

Adjust the assembly:

Check that the assembly height of the release bearing is sufficient to avoid friction between the outer ring and the diaphragm spring contact due to the sinking of the inner ring of the bearing after a long period of operation.

Ensure that the clutch diaphragm spring fingers are on the same plane, so as to avoid the bearing from colliding with the fingers during the rotating time interval to produce abnormal noise.

Repair and replace the relevant parts:

If the release lever pin and the pin hole are loose due to wear, repair the lever pin.

If the drive pin and pin hole are loose due to wear, the drive pin should be replaced.

Regular maintenance: To avoid frequent replacements, the clutch system should be inspected and serviced regularly to ensure that the release bearing is properly lubricated.

Inspection of related components: Sometimes the noise may not only be due to the release bearing, but may also be due to problems with the clutch pressure plate, clutch disc or other related components. A thorough inspection is needed to determine the exact cause of the noise.

Professional Repair: If you are unable to determine the problem yourself, you should take your vehicle to a professional repair shop for inspection and repair.

What maintenance is required after the separation bearing noise has disappeared?

After solving the noise problem of the separation bearing, in order to ensure the performance of the vehicle and prolong the service life of the related parts, the following maintenance measures can be taken:

1. Regularly check the lubrication condition:

   - Regularly check the lubrication condition of the release bearing to ensure that the grease is sufficient and clean.

   - Add or replace the grease at the intervals recommended in the vehicle maintenance manual.

2. Check the clutch system:

   - Regularly check the condition of the clutch disc, clutch pressure plate and clutch cover.

   - Verify that the clutch operates smoothly and that there is no abnormal wear or looseness. 3.

3. Transmission fluid change:

   - Change the transmission fluid according to the recommended intervals in the maintenance manual to keep the interior of the transmission well lubricated.

4. Driving habits:

   - Avoid frequent and rapid gear changes to reduce clutch wear.

   - Shift gears after fully depressing the clutch pedal and avoid prolonged stay in semi-linkage.

5. Cleaning and dust prevention:

   - Clean the gearbox and clutch area regularly to prevent dust and dirt from entering.

   - If any oil leakage is found in the clutch or gearbox, it should be checked and repaired immediately.

6. Listen for sound:

   - Watch for abnormal sounds in the clutch area during driving to detect potential problems in time.

7. Professional maintenance:

   - Follow the maintenance schedule and go to a professional maintenance shop for regular maintenance, where the professional technician will carry out a more comprehensive inspection and maintenance.

8. Record maintenance history:

   - Recording the time and content of each maintenance helps to track the condition of the vehicle and make future maintenance plans.

Through the above maintenance measures, you can ensure that the release bearing and its related parts are in good working condition, prolong their service life and ensure driving safety. Remember, regular maintenance and inspection is the best way to prevent vehicle breakdowns.

Summary

The release bearing is a key component between the clutch and transmission, and its function is to eliminate the heat and resistance generated by friction. When the release bearing makes noise, it may indicate that the bearing is worn, seized or poorly lubricated, which can have a significant impact on the normal operation of the vehicle. Therefore, once noise is detected in the release bearing, stop the vehicle immediately for inspection and take appropriate measures to solve the problem, such as lubrication, checking and replacing the bearing, adjusting the assembly as well as repairing and replacing the related parts. These measures can effectively solve the noise problem of the separation bearing and ensure the normal operation of the car and driving safety.
