The Talking Machine Forum — For All Antique Phonographs & Recordings

I recently bought at auction a Genola toy phonograph, not running. I want to pull the motor out. This requires that I get the turntable off. There lies my problem. The spindle top screws off--no problem. I think the turntable is a friction fit, such that I should be able to pull it off. It doesn't want to budge. Before I apply more force, I thought I'd check with the Froum to see if anyone has serviced one of these machines. Is that turntable in fact a friction fit? Any suggestions or cautions before I proceed?

Here are some pictures:

It shouldn't be a friction, or press, fit. It's probably just corrosion. Try putting a couple drops of penetrating oil, (not WD-40), where you removed the spindle top screw, (not down the threaded hole, but where the shaft and turntable meet). Let it soak in for a while, then put the screw back in, but do not thread it all the way down. Leave it backed off a turn or two. While supporting the turntable edges, tap on the spindle screw with a rawhide mallet or wooden hammer. Just several sharp "raps". Don't go nuts or you may bend the screw. This should help to break the turntable loose. Notice if after a few taps, the gap under the spindle screw has closed up due to the shaft being driven down.

P.S. You'll probably get some oil on the felt...

I shall give that a try . . .

PS: Thanks!

Brilliant! Profound! I will remember this. The idea is to back the spindle stop screw off a bit so's when you give it a tap, you're driving the spindle down independent of the turntable. Here's a picture.

Thanks, JerryVan. You're my hero.

Great news! Happy to help. Not every day I get to be a "hero"!

I've dismantled the motor. Everything was coated with a thick layer of very viscous grease, for example here:
The mainspring seems fine (I haven't opened the barrel). I think the grease was no longer acting as a lubricant but a deterrent. It has since been cleaned off. After cleaning one of the wheels, I found a trademark stamped into the wheel:
I have high hopes with a good cleaning this machine will once again do what it was designed to do, make music.

I think at least you'd better open the barrel to see how is the grease in the spring. You could find it nice, or you could find a black thick cake that prevents a smooth sliding of the spring, actually detracting a lot from the spring power.

Genola motor now running. And, Inigo, I had to remove the mainspring, not only to clean the spring and the barrel, but also to see why the spring was slipping and/or why the arbor was not catching the innermost hole in the mainspring. The problem was the pin on the barrel arbor; I adjusted how far it protruded so that the mainspring could get hooked and stay hooked.

The motor is quite simple. It consists of the mainspring barrel with a large concentric gear. This gear then engages with the pinion on another gear that turns the spindle. Finally there is the governor and a simple speed control mechanism. Runs quietly.

If any one wants a picture of the assembled Genola motor, please ask. I will take several before I put the motor back in the housing, which will probably be tomorrow.

The trademark stands for General Industries, Elyria, OH.

Thank you for the bit of info.

I thought Heineman made Heineman motors. Was there more than one manufacturer?
