That's what I was afraid of. When I pulled it out, before I even began to clean it, I thought it really "felt" rough and well, "lumpy".
I know NEVER to put oil in the motor...and I have the specific grease that is used, when any is used.
After I wiped the brush down, it looks and feels corroded and pitted. The machine ran fine at demo, but of course it wasn't a marathon sewing session.
Sure hope the motor isn't compromised....
My hubby is getting pretty good with my machines, between the 2 of us, people here, and repair manuals/ reputable sites, we're learning.
I found this:

But some of it is beyond what I've done. On the other hand, how does one learn??.. by doing...and yes, some trial and error.. Just a bit harder when it's something not easily replaced.
Thanks again everyone for your help.
