Allis "M" radiator rebuild/ rust electrolysis

 I ended up using a random long skinny rod, kroil, av gas, and air. after i got most of the tubes cleared enough I roughed up the coating of the rod and put it in my drill, running it back in forth while adding kroil. Now they are all clean and clear and hoping theirs no leaks. Not gonna lie might end up using stop leak if it does, since repair would probably cause more damage.

As for the bolts the worst was the lower outlet. I babied them when attempting to remove them gently rocking back and forth. I fought with getting it removed for hours. I couldnt use much heat because the soldier ect. I tried using a soldiering iron and propane torch, heating it a few times. Also used a super thin hack saw to slice through the gaskets (which were like the hardest epoxy or something. All so i could get drift between it and the radiator and help loosen everything. Ended up losing the battle that night but the next day my stepdad took a endmill to it and between a little beating, prying and wiggling back in forth it came off. VICTORY!! 

Thanks, it sure is! Even in the desert after 80 yrs, rust is one heck of an opponent.

Im really not looking forward to working on the steering clutches if they don't free up. 

Thanks for the advice I'll make sure to keep a eye on the temps. The fins seem ok, just green from the years. They are thin, but I think it will still work for what were using it for. (going to the yearly tractor show and maybe to pull something) It will probably get run a handful of times a year just to keep things moving ect.

I made some new brackets. It was fun since the old ones were stretched and the bolts dont all line up on the same plane. Then i took a burr to the rust and clean as much as i could without messing with the sealling surface. Still to scared to remove that since it might take to much of the sealing surface away. I also used a large square of sand paper and a flat piece of particle board to get the sealing surface as flat and even as possible on the tanks. Its probably gonna take a decent bead of rtv to seal everything. Glad the systems not under pressure. Still debating if we should try to use rust converter and red kote or another sealer. Or if we should just do the rust converter or nothing and run it as is. With how bad the tanks are rotted its hard to put money into them vrs maybe trying to find different tanks.

I also jb welded a piece that had broken of the corner of the top tank. We were going to braze it but since its so old and rusty we didnt want to risk it. Also cast iron is supposedly one of the hardest things to weld/braze and we dont have any experience doing it. So steel jb weld it is.

Also hears a pic of it with the hood and fenders off. Ive posted elsewhere but figure I should put one up.

As for running I dont know if it ever will, but it does crawl back in forth lol The steering clutches are stuck though so no left or right.
