    Posted: 09 Jun 2023 at 5:02pm
I received my new OEM light switch for my 1952 CA from B&B today.  One minor issue is that with my control box from the CA, the hole measures ~0.422 (7/16) inch.  The ferrule on the switch measures ~0.549 inches (1/2+) inch.  I can bore the hole out a bit or mod the ferrule on the switch to fit in the hole.  Have others found this issue?  B&B had not heard of this ever occurring before.  Did older tractors have a slightly smaller hole/ferrule?  Are people just going ahead and boring the hole out and not bringing the "issue" up?

...or should there be some sort of gasket?  The stem is really short, so seems like it would need to be a pretty thin gasket.

Aha.  The ferrule is removable and can be inserted into the hole first.  I thought it was for mere alignment.  Very odd design though.  The switch control rod plops out of its hole and is a bit awkward to install that way.  Virtually impossible to get a wrench on that nut :(  

So...it's a bezel instead of a ferrule.  If they had used the word bezel, I'da got it right away :)
