**Before installation, clean the mounting hole and outer diameter of the sleeve. Use a special press to cold press the sleeve in place. Do not strike the end face to prevent deformation.**
**After installation, ensure an interference fit (0.015-0.025mm) and a clearance fit (0.010-0.020mm) with the pin to ensure smooth and unobstructed rotation.**
**After assembly, check for coaxiality ≤0.02mm. Apply lithium-based grease promptly after installation.**
**For disassembly, use a special puller to remove the lug. When replacing, check the pin and mounting hole for wear. If wear >0.05mm, repair or replace the lug.**
