Frozen shaft in model E cylinder machine

[bangster]

Newbie here.  My regular gig is repairing clocks, but I've recently serviced a few spring-driven phonographs, and so have been brought a couple more.

This cylinder machine says model E (a previous D has been cancelled.  Its main shaft (not sure of nomenclature) is frozen tight.  Will not turn even a little bit. I decided it needs to be driven out. I removed all setscrews I could find, and used a brass drift & hammer on the left end. After much effort, it budged about a quarter inch then  seems not to want to budge more.  I decided I'd better seek advice.

So I'm seeking it.  What's the proper way to go about removing this shaft?  And what pitfalls should I look for along he way?

First off, what model phonograph do you have? Triumph, Home, Standard, or Gem? Pictures would help.

Your problem is most likely with a frozen pot metal bearing: this will have to be carefully broken out before you can remove the mandrel shaft.

Home, it says on the i.d. plate.

You might try putting the mechanism in the freezer overnight, this might help in freeing up the shaft. I would avoid any attempt to hammer the shaft out for fear of breaking

the stanchions. I have used a drill and a smallish bit to slowly break down the bearing, they are widely available and only a few bucks.

Thanks jeeprod. I'll figure out something.

I had the same issue on one of my machines. I carefully with a very small screwdriver chipped out the old bearing. Once about halfway done the rest popped out the other side. New bearing installed and back up and running. Good luck!
