The hydraulic throwout bearing, also known as the hydraulic release bearing, is a key component in the clutch system, and its setup and installation are critical to the proper operation and performance of the clutch. The following is a detailed analysis of the hydraulic throwout bearing setup:

I. Composition of hydraulic release bearing

Hydraulic release bearing is mainly composed of housing, piston, seals, hydraulic oil and other auxiliary components. These components work together to achieve clutch separation and combination through the hydraulic principle.

Second, the working principle of hydraulic release bearing

1. Initial state: when the clutch is not operated, the hydraulic release bearing is in the initial position, and the hydraulic oil is sealed inside the bearing to form a certain pressure.

2. Separation process: when the clutch pedal is pressed, a mechanical or hydraulic transmission device, the hydraulic release bearing exerts an outward thrust. This thrust pushes the piston inside the bearing to move outward, compressing the hydraulic oil and increasing its pressure. As the oil pressure rises, the hydraulic oil enters between the clutch pressure plate and the friction disc through a specific oil circuit, forming an oil film that separates the pressure plate from the friction disc, thus realising the separation of the clutch.

3. Combination process: When the clutch pedal is released, the thrust force disappears, the compression spring or other elastic element inside the hydraulic release bearing releases energy and pushes the piston to move inward, the hydraulic oil is discharged and returns to the initial position. At this time, the clutch pressure plate and the friction plate re-contact and transfer power, the clutch to achieve the combination.

Hydraulic throwout bearing setup points

Hydraulic throwout bearing setup preparation and installation

1. Identify components: Understand the main components of the hydraulic throwout bearing setup, including the bearing itself, hydraulic piping, bleeder valve, and main cylinder connection.

2. Protect hydraulic lines: Create a protective cover for hydraulic lines, such as a rubber hose, to prevent friction and premature failure.

3. Bleeder Valve Location:Make sure the bleeder valve is located on top of the hydraulic throwout bearing to ensure proper bleeding of the system.

4. Mounting the bearing:Replace the drive bearing retaining bolt with the stud provided and slide the bearing onto the bearing retaining shaft, making sure the stud is between the two fittings on the release bearing to prevent rotation.

5. Adjust for proper clearance:Use clutch alignment tool to verify proper alignment and adjust bearing height, provide shims using necessary clearance between bearing and clutch fingers.

6. Route hydraulic lines: Make sure they do not contact the rotating clutch or flywheel.

7. Connect to Master Cylinder:After securing the transmission and driveline, connect a line from the master cylinder to the input line of the hydraulic bearing.

Testing and Maintenance

1. Test the clutch system:After installation, test the clutch by shifting gears and observe if there is any abnormal noise or vibration to ensure smooth operation of the system.

2. Periodic Inspection:Periodically check the resistance or roughness of the bearing rings and replace the bearings if necessary.

3. Piston and Seal Maintenance:Disassemble and inspect pistons and seals for damage, clean them before reinstallation, and replace seals with recommended kits if needed.

Advantages of hydraulic separation bearings

1. High precision and stability: Hydraulic release bearings realise the separation and combination of the clutch through hydraulic principle, which has high precision and stability.

2. Long service life: the lubrication of hydraulic oil reduces friction and wear, prolonging the service life of hydraulic release bearings.

3. Low noise: the smooth operation of the hydraulic system reduces noise generation and provides a more comfortable driving environment.

4. High load capacity: hydraulic release bearings can withstand large axial and radial loads to meet the needs of high-performance clutches.

In summary, there are many aspects to setting up a hydraulic release bearing. By following these detailed steps, you can ensure that the hydraulic throwout bearing is set up correctly for more comfortable and efficient clutch operation. Hydraulic throwout bearings play a vital role in the smooth operation of your vehicle's clutch, and proper setup and installation is important to ensure proper clutch operation and improved vehicle performance.
