Suggest try heat (with a propane tourch or heat gun) on the clamping (outside pieces) only - . You have to get the parts quite hot so wear gloves. High heat expands the "clamping" of the corrosion bond and allows the liquid wrench to penetrate the "corrosion bonded" parts. Do this a couple of times. allow to cool - then when hot, striike a sharp blow to the mating parts surfaces - not to hard - just a sharp blow.Then a little twist and it should come off. If you had ever removed a brake drum from a old (1930"s) ford with keyed - tapered axles that was the only way to do it. Its a common practice. Try not to melt the seals (if any) but heat is about the only way to do this. Wear gloves and use the proper precautions. A good machine shop or automotive shop can do this for you also. DON"T use a puller unless you have to as it will distort the parts. Let me know of this works. Assemble with some corrosion preventitive lubricant. Sam in Daly City

Seemed like it would just be a matter of taking out the set screws and
turning it a bit while pulling up on it, but this was not the case.
Basically, I have concluded that it is absolutely impossible to remove
the wheel head. I have tried liquid wrench, letting it soak over night
and then taking the whole top part of the wheel off and putting the main
shaft in a bench vise, and then held the wheel head and pulled up on it
while turning it back and forth for a long time, and It did not move up
at all.
Has anyone out there had to deal with this, and if so, do you have any
advice on how I could remove this wheel head? I know someone who works
at a machine shop but I don't even know what kind of tools they would
have that could do this without damaging the wheel head. I would be very
thankful for any advice out there. Sergio from Laguna was nice enough
but the only suggestions he had were to do what I just mentioned, and it
did not work. Thanks!
