I'm working on a Philco model 37-650. By the way it's nice to be back. I've been restoring radios for about six years now and have come a long way since I last visited here. The Phorum appears to have changed a bit (I think) so bare with me as I get used to all the new stuff. Or maybe I was just gone too long.
I need to get into this RF section to change out components and do a thorough cleaning. Someone really chopped this set up even leaving paper caps down inside this section because they couldn't get them out. Capacitor blocks that still had readings within tolerance but new caps were installed in parallel/series with these blocks etc. Real mess. Here's a pic of the RF section. I hope I did it right.

The shaft that goes through all of the bandswitch wafers is secured by a plate on the front of the RF section. I removed the two screws and it appears as if this shaft wants to slide straight out. I understand that I'll have to be careful to not disturb the clocking and the wafers are individually held in with their own hardware. The whole RF section looks like it comes apart in order to get to everything. Question is does this shaft slide straight out without messing anything up? Obviously my first 37-650. Worse Philco RF section I've worked on was a 46-480. Had burned components under it so it had to come out. What a bear. At least there's room here to navigate.
Thanks much,
John
