What are the common problems when using the locking sleeve structure slack adjuster?

1. Improper slack adjustment
Problem manifestation: The sleeve body of the Locking Sleeve Structure Slack Adjuster is not aligned with the end face of the sleeve cover (such as the brake shoe adjuster needs to be flush with the end face), resulting in low drilling accuracy or elastic pin riveting offset. If the wheelbase or input and output axial position of the intermittent divider is improperly adjusted, it may cause vibration, abnormal noise or even transmission failure.
Cause: Manual adjustment error, worm gear wear or self-locking mechanism failure.
Maintenance suggestion: Use special tooling (such as V-type support seat and clamping assembly) to fix the sleeve to ensure that it is rotated in place; calibrate the axial position regularly to avoid unauthorized adjustment by the user.

2. Seal failure and medium leakage
Problem manifestation: The sliding surface of the cylinder compensator is corroded or the sealing ring is aged, and it still leaks after the bolts are tightened; the brake seal is worn and causes brake fluid leakage.
Cause: High temperature environment accelerates the aging of sealing materials, lubrication pollution or failure to clean the oil port during installation.
Maintenance suggestions: Regularly check the sealing device and replace the sleeve or seal ring with severe corrosion in time; strictly clean the oil circuit during lubrication to avoid impurities.

3. Wear caused by insufficient lubrication
Problem manifestation: The needle bearing in the sleeve of the locking sleeve structure clearance adjuster is stuck, the worm drive resistance increases, and even reverse impact occurs.
Cause: The lubricating oil is not replaced according to the cycle (the first 1000 hours, and then every 3000 hours or every year), the oil viscosity does not match or the lubrication points are not fully covered.
Maintenance suggestions: Use high temperature resistant grease, clean oil stains and iron filings regularly; complex structures can use oil injection lubrication system.
