PS3 accepting disks but not reading them. Also maybe GLOD?

So, I recently bought a PS3 fat CECH-K01 off of Mercari, and after cleaning it and ridding it of YLOD, I decided to turn to the problematic disk drive. It will accept my disks, but won’t read them. I’ve opened the disk drive up, and discovered that the mechanism is a bit wonky. The black bar on the side doesn’t connect to the black gear unless I move it, but I can’t do that when the top cover is on. It also doesn’t help that the PS3 has video output issues. I was very excited to fix this, so help with either of these problems would be very much appreciated. Thanks!
