I have found that it is very difficult to successfully remove these
insulators whole. But I have done it a couple times. The way I have done it
is to dig out all the tar surrounding it. Then there is a clip holding the
insulator in, once you remove that and you removed all the tar it might just
come out. If your transformer is not potted in tar it's pretty much
impossible to get them out. Good luck.
