I got a used DM today. When I opened it to clean the bearing I found it was stuck to the axle half. After trying pliers and smacking the crap out of it, I found a post on YYN by sicyo 8) that fixed the problem. Heres my take on it.
Take a yoyo string, preferably an old one your not going to use again and wrap it one or 2 times around the AXLE. screw on the other half till it’s tight, then unscrew. the bearing will be stuck to the other half and will come off it by pulling the string.
can also be used to get it off the non axle side by screwing it on a 2 or 3 turns, then wraping the string around the exposed axle, tighten, unscrew etc etc etc.
Worked great!
Can post pix in necessary .
Apologies in advance if this has been posted already.
