To check the degree of wear of the separation bearing, the following methods can be taken:

1. Appearance inspection:

Primarily check the housing of the RELEASE Bearing for wear, scratches or cracks. These cosmetic damages may indicate that the bearing has experienced more severe wear.

Check the grease or lubricant of the bearing for leakage or contamination, which may also be an indication of bearing wear.

2. Sound check:

Listen carefully to the sound the release bearing makes while the vehicle is running or being tested. Under normal conditions, the release bearing should be noiseless. If there are rattling, knocking or rubbing sounds, these could be signs of bearing wear or damage.

3. Temperature check:

Use a tool such as a static tester or infrared thermometer to check the temperature of the release bearing. If the temperature of the bearing is abnormally high, it may be due to poor internal lubrication or increased friction, which is usually associated with bearing wear.

4. Friction check:

Where conditions permit, the friction of the release bearing during clutch engagement and disengagement can be checked. If the friction is excessive or erratic, it may be an indication of bearing wear. Please note, however, that this method may require specialised equipment and skills.

5. Clearance check:

Check whether the clearance of the RELEASE bearing exceeds the specified range. Too much or too little clearance may lead to bearing damage or abnormal wear. This requires the use of specialised measuring tools for accurate measurement.

6. Relative rotation check of inner ring and outer ring:

Check whether the inner ring and outer ring of the release bearing rotate flexibly relative to each other. If the rotation is not flexible or there is a phenomenon of jamming, it may be a sign of bearing wear or damage.

7. Measure the diameter: Use calipers to measure the diameter of the release bearing and compare it with the diameter of the new bearing to determine if there is a significant reduction in diameter.

8. Check the lubrication condition: Check the lubrication condition of the bearings. If the grease is black in colour or there are metal shavings, it may indicate that there is wear inside the bearings.

Tools that must be used when replacing bearings

The following tools are usually required when replacing a RELEASE bearing:

1. Bearing extractor (bearing remover):

Used to pull the old bearing off the shaft or seat bore. Commonly used are claw bearing extractor and hydraulic bearing extractor.

2. Bearing hammer:

Used to knock the bearing, in order to break the bearing and seat hole adhesion, easy to take down the bearing. Commonly used hammer and pneumatic bearing hammer and so on. Pay attention to the strength of the use of master, to avoid excessive hammering parts damage.

3. Bearing installer:

Used for mounting new bearings to ensure that the bearings can be evenly and easily pressed into the seat holes during mounting. Commonly used manual bearing installer and hydraulic bearing installer and so on. When choosing, pay attention to its size and accuracy, so as to avoid errors leading to installation difficulties.

4. Measuring tools:

Such as vernier calipers, depth gauge, etc., used to measure the size of the bearing and clearance and other parameters to ensure that the installation of new bearings is accurate.

5.Other auxiliary tools:

5.1 such as bearing special clips, drive shaft remover, oil filter element remover, etc. .

5.2. Wrench: for dismantling and tightening bearing bolts.

5.3. screwdriver: for removing screws that may be present.

5.4. Hydraulic pump or compressor: used to pressurise the clutch hydraulic system to aid the removal and installation of the release bearing.

5.5. Cleaning tools: e.g. cloths, brushes, etc. for cleaning the bearing and housing from dust and dirt.

5.6. Grease or lubricant: for greasing new bearings.

5.7. safety stands or jacks: for supporting the vehicle to ensure safety.

5.8. Hydraulic hose fittings: If hydraulic hoses need to be replaced, hydraulic hose fittings may be required.

These tools can assist in the various steps of the release bearing replacement process and increase the efficiency of the replacement. Please note that when replacing the release bearing, in addition to using the necessary tools, it is necessary to follow the correct procedures and safety practices to ensure safe and effective operation. If unsure of how to proceed, it is recommended to seek professional assistance.
