I have a post war ZW transformer and my dog ate the right large handle. I have a new handle to replace the one that the dog ate. but I can't figure out how to take the handle off. Does anyone know how to remove and replace the handle?

Use a 4-40 X 1" screw to "run in" on the hole in the center of the dome portion of the handle. See figure 1.

Thanks for your help. What holds the new handle on after you have drilled the center hole with a 4-40 X1 inch screw?

It’s a friction fit on the shaft. The handle has a 4-40 nut imbedded in it so when inserting the machine screw, it pushes against the shaft to remove the handle. The screw is only used to remove the handle.

You don't drill the center hole, you just use the screw to remove the handle.
@360RPMHere's a link to Tranz4mr's step by step guide to ZW _Handle Replacement which may be helpful.
Thank you for the info on removing the ZW handle. I went to the hardware store and asked for a 4 X 40 X 1 inch screw and they had no idea what I was asking for. Pardon my ignorance, but what is a 4 X 40 X 1 inch screw.
If you can't find the screw go on the trainz web site and type in ZW parts they have the entire right-hand assembly.

4-40x1 is a number 4 screw, 40 threads per inch, 1” long. Find a better hardware store, an old school one.
360RPM,
a 4-40 screw is a number 4 machine screw with 40 threads per inch.
If you have an Ace Hardware in your area you should be able to find the screw there.

I see Jon answered you question as I was typing.
I thought dogs only ate ‘homework’ ?

Or find a clerk with gray hair and ask them.
will the same procedure using the 4-40 x1 work for the ZWC handle?
