ZW - how to remove BC dial (handle))

Are you asking or telling?

As far as I know, the inner dials are fixed to their shaft and are not removable.
Same goes for the wiper arm on the other side.
The entire assembly is removed as one piece.
You have to remove the whistle / direction control and all the stuff under it.
Then the assembly lifts out.
If you have not removed the outer handle, it will come out too.
I think I have one of the assemblies in by shop, do you need a photo?

I took the dial off of a shaft once.
The shaft was heavily knurled underneath the plastic (not splined). It was definitely made NOT to be disassembled.  (of course they could have modified the assembly over the years)

CW - asking.  I was thinking that the bushing would help hold it together.  Maybe CA glue?   A picture would be great !   Thanks Art

Here are a couple of pictures. Note the diamond pattern on the end of the tube. The control dial goes there. With a pattern like that, I am guessing that the handle was molded around the shaft.
The second photo shows the whole assembly (wiper arm is bad).

Why do you want to separate the handle from the shaft?
I don't see how it could slip out of place. If anything was to slip, I would think it would be the wiper end. But I have not heard of one slipping there either.

Thank - you for the photos. I see what you mean.  How could it move. (?)  Could the arms be installed wrong? Is there a correct way to have them lined up be for pin is reinstalled ?    Art

The arm is also fixed to the tube. (see the pictures again). I suppose that joint could loosen and slip. But I don't think I have heard of that being a problem.

Thank you for your input.  I held the BC arm and tried to move the BC dial - only slight movement was noted. Please see the enclosed photo which clearly shows  some type of movement must've happened. How did you remove your BC Dial from the arm?    Any other ideas to repair this problem ?

Not all the tubes have a diamond pattern. Some have a straight knurl on them that might come off. The dial is not a BC dial. It is either a "B" or it is a "C". It looks like the C dial is on the B side. They are labeled on the dial next to the numbers.  Something like "voltage post BU".  Are you sure it is the correct dial assembly for that side of the transformer?

The dial is on the right side or the numbers would be backwards.  The 20 is in the correct position for the right side.  If it were the left side, the 20 would be on the other end of the string of numbers.

Look at the position of the roller arm compared to the dial. The dial is at max voltage. The arm should be all the way towards the terminals. The positioning of the roller arm and the dial is out.
If the tube on this transformer is like the one David pictured, then the dial may be in the wrong position. If the dial is locked in place (and cannot be removed), then I guess the arm did move on the tube.

 How did you remove your BC Dial from the arm?


It was a destructive removal resulting in a broken dial. The arm was bad anyway. I wanted to see how to get the dial and shaft apart. Don't remember exactly what I did, but it resulted in a broken dial.
I guess I kept the shaft as a reminder that the pieces don't come apart.

Good to know for us beginners who think something 'outa come apart/off.  Ain't necessarily so!!
