It looks like in your pic at your first post on page 1 of this post, that the brake drum was in the wrong position, and was rubbing on the bolt heads on the retainer. Sometimes the setscrew comes loose, or if people don't tighten it enough, and the brake drum moves.
Dale Finch showed this in her post about repairing a brake.
The brake drum has to be put onto the axle shaft until it is against the shoulder on the shaft.
Below is Dale's post.


Also, the bottom dowel pin looks like it is gone, there is a hole there for it. There should be a dowel at the top, and the bottom. They are important to keep the casting from working around on the bolts.
It may be there, and stuck in the hole on the final drive. If so, I would try to remove it and hammer it into the transmission housing hole. They are supposed to be in the trans housing, like the top dowel is.
It is supposed to be tight in the trans case, and slide off the final drive casting.
TM Tractor has a new dowel, if it is gone. Below is their listing. There are pics there of the dowel locations. :)

Slide axle pullers are good for that. You can buy them at a lot of places, or Autozone, O'reilys, etc. loan them. You have to give a security deposit equal to the price of the puller, but it is refunded when the puller is returned in good condition.
If you are not part of the solution,
you are part of the problem!!!
