Ok, I just finished with the 301. It's back on its shelf with disc 5 of Instrumentals Complete playing. As I begin to type the theme from Bonanza is playing, about to transition into the theme from Exodus.
First, the instructions McIntosh sent seem to be for an older build of the 301, as getting the top cover off is the same as for the C2300; two screws at the front and the two on the back of the top plate come out, then one side panel is removed. The screws weren't "nailed" in place as they were on the 2300, though.
It was a simple matter to adjust the screws on either side of the CD tray, and by eye at least the tray is now dead center in the slot. I tested it before and after placing the 301 back on its shelf. It sounds about the same as it did before. The scraping noise is gone. Now that it's back in place I'll probably play another disc or two to see if anything changes, and keep an eye on it over the next few days. I just heard a bit of distortion, like static, come from the left speaker (my computer is right next to it). Not sure what that is, unless it's in the recording and I happened to be close enough to hear it.
Anyway, the tray is working properly as of right now. The theme from The Magnificent Seven is playing.
