Hydraulic throwout bearing for clutches

A hydraulic throwout bearing is a component used in automotive clutch systems to hydraulically disengage and engage the clutch. The bearing is located between the clutch pressure plate and the clutch pedal. When the driver depresses the clutch pedal, hydraulic fluid is pumped to the hydraulic cylinder in which the release bearing is located, generating pressure that pushes the release bearing, which then separates the clutch pressure plate from the flywheel, interrupting the transmission of power from the engine to the gearbox. This design is intended to provide easier handling and smoother clutch action.

Causes of Hydraulic Throwout Bearing Not Engaging

When the clutch hydraulic throwout bearing is not engaging (i.e., the clutch is not engaging), possible causes include:

1. Hydraulic system failure: Insufficient hydraulic fluid, leakage, contamination or damage to hydraulic cylinders, pistons and other components in the hydraulic system may result in hydraulic pressure not being established or transmitted, thus affecting the normal operation of the bearing.

2. Mechanical failure: the internal mechanism of the bearing is damaged, the connecting rod mechanism is broken or loose connection and other mechanical failures, may also lead to bearings can not work properly.

3. Improper operation: Drivers may have improper behaviour during operation, such as half-pressing the clutch pedal for a long time, leading to overheating or increased wear of the clutch, which in turn affects the engagement effect of the bearing.

4. Problems with the clutch disc: severe wear of the clutch disc or improper installation may also cause the clutch to fail to engage properly.

5. Damaged hydraulic cylinder or piston: Internal wear or damage affects its normal operation.

6. malfunctioning control valves or pumps: problems with hydraulic control components that affect the oil pressure supply.

7. Improperly set pedal travel: causing the hydraulic system to not respond properly.

Hydraulic Throwout Bearing Care and Maintenance

In order to keep the clutch hydraulic throwout bearing in good working order and to extend its service life, the following maintenance and servicing measures can be carried out:

1. Regularly check the hydraulic system: Ensure the cleanliness and sufficiency of the hydraulic oil, and replace the aged or polluted hydraulic oil in time. At the same time, check whether the various components in the hydraulic system is intact, if damaged should be replaced in a timely manner.

2. Keep clean: keep the clutch hydraulic release bearing and its surrounding environment clean, avoid dust, dirt and foreign matter into the hydraulic system.

3. Correct operation: The driver should operate the clutch pedal correctly, avoiding half-pressing the clutch pedal for a long time or pressing it frequently. Make sure the clutch is fully engaged or disengaged when starting, shifting gears or stopping.

4. Regular inspection of the clutch disc: Check the wear of the clutch disc regularly, and replace it in time if it is badly worn. At the same time, make sure the clutch disc is installed correctly.

5. Lubrication and maintenance: For parts that require lubrication, regular lubrication and maintenance should be carried out in accordance with the manufacturer's requirements. Pay attention to the use of appropriate lubricants and lubrication methods.

6. System check: Periodically check the hydraulic system for leaks, piping and fittings.

7. Pedal Stroke Adjustment: Adjust the clutch pedal stroke according to the vehicle manual to ensure the correct working pressure.

8. Professional service: When problems are encountered, they should be checked by a professional technician and worn parts should be replaced if necessary.

Summarising

The clutch hydraulic release bearing is an important part of the clutch system, and its working condition directly affects the clutch release and engagement effect. In order to maintain its good working condition and prolong its service life, it is necessary to check the hydraulic system regularly, keep it clean, operate it correctly, check the clutch disc regularly and carry out necessary lubrication and maintenance. At the same time, the driver's standard operation is also one of the important factors to ensure the normal operation of the clutch hydraulic release bearing.
