Well, I tried to take apart this old dirty Yaskawa servo and that included removing the encoder. Mistake! The encoder hub wouldnt come off- lok-tite. So I gently heated the shaft with a tiny pencil torch. This happened:
Attachment 296252
Attachment 296254
Attachment 296256
It was some type of easily meltable plastic. So can I get a replacement disk? Or am I stuck putting another encoder on there?
Im so sorry...
