Philco 37-10 Vernier Dial Disassembly
#1

I am working on a Philco 37-10, a smaller brother of the big 37-116 which both have the teledial. The vernier does not rotate smoothly. It feels like it has flat spots on the bearings. I tried to use penetrating oil to loosen up the grease but the flat spots are now more noticeable. ;-)
I tried to do my research and saw a number of good articles as always on the ARF as well as Philco forums:

I would like to take this thing apart and see the condition of the bearings and perhaps replace them. From one post it appears that Mark Oppat may have bearings for this drive assembly. The posts make mention of a clip which I do not see anywhere (see photo below). I do see a pin I believe at the red arrow in the photo but pushing it in has no effect. I wanted to see if that is indeed what is holding this together before I do anything stupid and force it. Appreciate it if anyone can comment on this and help out.

Lou, the pin doesnt go in, you need to pull it out. Use a magnetic pickup tool or similar and the pin should come out. Put this assembly on a towel to catch all the small parts that will fall out.

I bought a small rare earth strong magnet and that pulled the pin out nicely. So thanks for the advice. Now cleaning everything and hope those bearings are still good. Luckily I did this in the den and not my shop because some pieces like that spring went flying and I had to find them in the rug with that magnet ;-)
I do not think there was a bearing between the know of the vernier shaft and the head of that rivet looking pin that goes atop the spring... I hope. If so I will need to keep looking for another bearing.
