I'm a bit confused about exactly which part you're trying to get off now. Are you trying to get the axle shafts out? Some of those old axles have cone shaped bushings under the nuts or bolts that hold on the axle shafts. They are #1142 in Mark's picture above. Once everything is tight, those suckers really get wedged in there. They look like this:



The best way I've found to get them to loosen up and pop out is to tap on the side of the flange of the axle shaft. If you follow the arrow from #1144 in that picture, smack the tar out of it right there with a brass mallet all the way around it's diameter. That's usually enough to loosen them up and get them to work out of the tapered holes.

You can also swat the center of the end of the axle shaft two or three times with a hammer. The cone washers will bounce out far enough to be able to pull them off of the studs with a pair of pliers.

If your holes are centered pretty well in those flathead screws, I'd just go after them with an 82 countersink and remove the heads altogether. Forget about the threaded part.

So in my stupidity I managed to shear both adjustment bolts, the big ones with the springs behind them, and now the drum wont turn at all. Guessing I adjusted the shoes all the way out and then sheared the bolts.


Scale of 1-10 how screwed am I?

Twenty. I don't see an easy way out now. You're out a backing plate now regardless, unless there is enough adjustment left on the anchor bolt eccentrics to back off the brake shoes. Even that is going to be iffy.

Those top adjustment bolts turn cams that adjust the shoes toward the drum. Since you twisted the bolts off, you may be able to take a punch and drive the cams in and out of the backing plate so the shoes will collapse inward. I have quite a few of those backing plates if you are in need of one. Again, I would not make any more attempts to remove the drums from the hubs, to keep from damaging them. I would remove the hubs and drums as an assembly.

Will they remove the drums without damaging them?

They're the most highly regarded classic car/truck brake shop in the area so I'd bet if anyone could it would be them. Let's find out!
