 I have already removed 3 wheels, but the last one does not want to go down, it is very seared. How is this wheel removed? 
 A method that is several dozen years old:
 Pour the kerosene, leave it for an hour, pour it again and after another hour it should come off easily. You can "help" it by lightly tapping it with a wooden or rubber hammer.
 You can moisten with some rust remover, but it is quite risky due to the aggressive ingredients that the rust remover contains (WD40, etc.).
 I used to have a Spanish spray called Caramba, it was very good but unfortunately it's over ...
