Разборка и ремонт вентилятора Soler&Palau silent-100 cz

Disassembly and repair and replacement of the fan bearing 624z. The fan worked for more than 5 years and the bearing hummed. I myself found how to fix it on only one resource, but I did not find a video on Youtube. Although initially I also looked on Youtube, unfortunately, only empty reviews. See fix it and you will succeed! As I did ..) Write if the video helped you and fixed your fan. God help and remember "The eyes are afraid and the hands are doing" ...)))
