Zenith Turntable locked troubleshoot inquiry part 2

First video of my problem: https://youtu.be/Qh5pqC4FG8k

I continue to attempt to troubleshoot my zenith console turntable. I apologize for my complete ignorance of the part names of the turntable.

I later found out that the black wheel I was looking at is called an idler wheel.

I'm beginning to think I'll need to pull the entire turntable out of the console. But I'm curious if anyone has any initial ideas as to the problem
