Early VV-IV Phonograph Questions

[benjaminh]

What I was actually thinking is getting a round coupler nut, epoxying it on, and pulling out the extension with that. I realize that this probably mean rendering the extension useless, but I really don't think that loctite will hold well enough to do the trick. I've reached inside, and the extension is on pretty tight.

Does anyone know the exact thread size for this machine? The serial number is on the first page...

I was thinking of one of their epoxy products like this:

Sure that product might work, but from the quick research I just did, it might prove rather difficult to “undo”. If someone has the thread size, I'd prefer potentially sacrificing a nut and the extension, than a crank and the extension.

Here are two pictures of the tonearm -bracket connection. Are there supposed to be bearings, or did the early ones not have them?

I have that model and the turntable should just lift right off..

This one uses the early style motor which is also used on some of the early external horn machines, and not as common of a motor.

Also, you should be able to use pliers and grab around the extension bar, also make sure you have the correct flat crank for the machine.

No bearings on this early IV setup. Just clean it good and use a light grease to seal for air leaks and lubrication.

Well the extension bar certainly can't be just grabbed by a pair of pliers. I've tried many times with a pair of needle nose pliers (the only ones that can remotely fit) with no luck. Unfortunately, the platter doesn't just lift out either. I've gone through many rounds of penetrating oil, and trying to knock the center spindle through with a mallet, with absolutely zero success. I'm going to try heat, and if that doesn't work, I don't know what will.

With this early IV you should be able to remove the back bracket and using the hole in the case get to parts of the motor.

Loosen the set screw in the spindle gear so you can pull the turntable and spindle out together.

Then you can work one the spindle and turntable on the work bench. Use a torch flame or press if its still stubborn.

So if I remove the gear circled in red in the image below, the spindle and shaft should lift out?

Yes that is what will happen. Loosen the set screw that holds the gear to the spindle. Then the turntable and spindle will pull up out of the gear, leaving the gear behind in the case.

Note that the gear could be stuck on the spindle from old grease and oil. But it won't be rusted and can be broke lose.

Very important make sure the motor is run down with no tension on the main spring.
