Those rollers are pretty badly worn... for sure.
I just fixed my 2046... looks like the same issue ...but, I could be wrong. On mine the roller *plate*... the metal piece that holds the rollers was *not* secured tightly to the insulator underneath it. Whether this is the correct fix or not I don't know... but, once I aligned my roller plate with the insulator... I pulled the roller plate out about an inch, wiped the roller plate and insulator with Q-tips and some alcohol (I did not go nuts with this... just got the grease off) and used contact cement to glue it back together. Now it sits on there tight and the rollers do not wiggle around or get stuck when raised up towards the insulator. She is a little BEAST!
I think I'm good for another 67 years (the 2046 was purchased Christmas 1953).
