1985 125M axle drum FROZE, wont budge!

Hello . What would prevent the removal of the brake drum off a 85 red 125M ? Do I need a puller ? The Axle wont even turn at all. I have the rear brake componants disconnected too btw

So far I have noticed the brake shoes in the rear drum are not moving a bit. The brake arm is also very frozen so that makes me think the arm is the primary cause of the problem. I guess for now Ill have to work on getting the brake arm free. But it just makes it even MORE difficult when I cant see the brake cam thru a hole in the drum !! Any suggestions ?? Heat? PB blaster? Pipe wrench? Hammer ?
Earlier I used a hammer and punch on the drum to maybe make it turn a smidge , NOTHIN. I even put a 18 inch pipe wrench on the flange of the brake drum and nothin! I mean it is FROZE!
This is torture and its the only thing keeping me from the first test ride on my new machine !Help!

Penetrating oil all over any part of the cam that you can access and then wait. Might take a day or two sometimes and multiple applications but that's how it goes. I wouldn't use heat until you've tried the penetrating oil. Try tapping the brake arm with a deadblow or a wood block back and forth (lightly) after it's been soaking in that oil.

I accidentally broke a drum once beating on it with a punch so be careful with that

Yes sir we got it !!I have now learned all about the rear axle and ( I think ) all the components . I got it all back together ( correctly ) and even got to take it for a spin before the new brakes and bearings come in ! Pretty darn happy !! Thanks all you 3 wheelin maniacs ! Iron chop !!
