[without breaking it?]

Me and a relative have been trying to get the brake drums off a 1941 International. We've tried penetrating oil, heating the hub, attaching a large three-jaw puller to the outside of the brake drum and all those things at once, but none of these really work. So does anyone know what might work?

Thanks!

Hotter heat? Map or oxy? a propane torch wont do shit!. 41 international what? They are probably junk anyway and can be replaced..

hmmmm. this will sound dumb. but have you tried (while the car is still on stands) get a jack under the drum. and try and lift it and lower it enough to break it loose? yeah a sledge can weigh a good 10-20lbs but a car weighs alot. more force might work

In order: mallet, hammer, torch, on the INNER diameter where the lugs are (put lug nuts on loosely to protect the threads from hammer strikes), not the OUTER braking surface which isn't rusted on.

Lastly see if it has a couple of threaded holes you can put screws into and turn until it pops off. Discovered them on my Z's thoroughly rusted rotors, and it was much easier than the prior methods we tried.

You can see them in this picture (two smaller holes that aren't the 5 lug nut holes):

Same on my 66 chevelle last time I had to use the two screw holes. I actually added them to the new drums since they worked so well

Did you go through the access hole in the back of the dust cover and turn the starwheel to back off the pads away from the drum? If the pads are on the drum, it's not coming off. Also, I'm not familiar with the old internationals, but be aware some drums are held in by wheel bearings (crap design) and some drums have a screw/bolt in the front alongside the wheel studs holding the drum to the axle shaft.
If none of those apply then it honestly sounds like you're doing all the right stuff, so just turn it up a notch. More heat, bigger hammer, more liquid wrench, bigger puller.

I know how. will send pic of tool I made to do it tomorrow if I have time. In the mean time pick up one of those pistol grip air hammers (they're cheap). Also you'll need a welder.
