    Stuck wheel

    I've got 4 wheels that are not moving in the tone generator. I was able to prop up the TG a couple of inches and observe the movement by shining a light underneath. I've read through the threads and the recommendation is to use Naphtha or Alcohol to clean up the TG.
    If there is only 4 wheels with a problem it seems that i should treat the problem locally. So my question is should i use a syringe with Naphta on the stuck wheel? or on the gear next to it or spray the general area? It looks like the inside of a clock and i'm guessing it is fragile.

    I just put my finger on the non-turning wheels and force them to spin. they typically will free up and work. I also am not opposed to spraying WD-40 on them to help get them going. Then, followup with a good oiling. One way to know they are really free is they should have side to side motion that is very easy easy. Done.

      If you can prop the TG up enough to get to the wheels, just put a couple drops of Hammond oil on the bearings and rotate with your finger to free them up.
      Each set of 2 tonewheels has bearings on either side. The main shaft has a series of bearings along it's length.
      That should fix it.
      While you are at it, go ahead and put a drop of oil on all the other wheel and main shaft bearings...there are a lot of them.
      If you have not already, oil the TG when you have it back together and you should not have any more issues.

      If you are interested, this video shows a TG in detail.

          They are freely moving now. Thanks again for the great advice

            Sorry to hijack your thread,but I've been trying to get some information regarding the main shaft in the generator.
            I recently got a B3 that had sat unused for many years. I've been oiling it faithfully and making some progress as far as getting the start motor to engage and turn for a short time time before binding. The run motor side of the generator has yet to turn when this is happening and I manually manipulate the axle until I would meet with moderate resistance. Friday when I was doing this the axle finally seemed to spin freely,however the start motor side remains resistive and it feels as though there's no mechanical connection between the two sides. I know there are spring couplings all through the shaft,could I possibly have one that's failed?

              It is not uncommon for one of the spring couplings to either break or become dislodged.
              Forcing one end to turn if the other end is stuck can cause this.
              If you can rotate one side more than one revolution without the other end moving at all, it sounds like the coupling is broken.

              Unfortunately this is not an easy fix.

                Gee, Bob, I had seen that video before, but not all the way through. This time, I finished it and was hyperventilating (brown bag) watching you drive the pickup rod into the wheels, and unroofing those delicate threads in the oil trough. Even then, it amazed me how robust the pickup and gears are.

                I like to tinker, but I will not ever, ever tinker in that area, which is over 60 years in my old B3, and is doing just fine, thank you.

                Thanks for the anatomy lesson.

                  Thanks for the info,Bob. It didn't seem to be a good sign to me,either.
