Pulling a running gear apart

Hello, I am looking for any suggestions on pulling apart an older running gear. I am in the process of refurbing it and I can't get it apart. I have pulled all the pins/bolts that held the center beam together but it is rusted/frozen together yet. I have also tried to hook it to a tree and pull it with my tractor but I don't want to break it either.. I have put PB blaster around the tube as well to try to help loosen it and used a large pipe wrench to try to turn the back side portion to loosen it.

Only other thing I thought of was trying to heat it and see if it will come loose. The problem with that is I only have a small burnzomatic torch that you normally only use to water pipe work. So I don't know if I can get it hot enough to matter or not.

I am trying to shorten the gear. Its a bit longer than I want at the moment and I would like to take 1 or 2 feet out of its length to help it turn a bit tighter.

If anyone has any other ideas let me know.

HI Guys

Took multiple folks advise. Went out and bought a MAPP gas torch since I have no oxy/act torch handy. hooked my super A to one end and chained the other to my JD Compact. Heated it for abou 5 minutes with the torch. Broke my chain 3 times trying to pull it apart before I decided to get my logging chain... Its heavy so its always the last option. then yanked her apart!

Thanks for the tip on the Mapp gas and all the other helpful hints.

Now we have to disassemble the rest of it. repaint. and put her back together before spring.

Would depend on how bad I wanted that joint apart... If I really wanted to get it apart, then probably heat, or some nipping with a torch if the pipe is burred up. Otherwise I'd be tempted to cut the pipe in a convenient location with a cutting wheel, measure out how much I want to remove, cut that out, and then join the pipe back together. That would also depend on what I had at hand to jig the pipe for welding it straight. Otherwise, heat and force. I'm crude like that.

Thanks for the replies so far guys! I'll just keep at it. Might check into the MAPP gas and see what that is like as well. I'll probably jack the back end up as mentioned first and try to get it gonig side to side if I can maybe. I'll have to reinsert some of the pins.

Thanks again!

You need to get an acetylene/oxygen torch to put plenty of heat on it. You could get a small cylinder of mapp gas. It contains acetylene gas
and will burn hotter. Home Depot has the cylinders. Plumbers use this too. Hal

Had the same problem this summer when I made one longer. I jacked it up so the rear wheels where off the ground and then pushed down on each wheel so as to make the pipe turn inside the other tube. At first it didn't want to turn and I had to lift with a chain hoist on one side then the other but after doing that a few times it came loose. Once you get things moveing I would pull it all the way apart and clean up the pipes as best as you can. I know you can't clean the inside of the one but you can clean the out side and that helps a bunch. Then before you slide it back togeather grease it up good so its less likely to rust up as bad again

In addition to the rust and dirt, there are probably some burrs around the holes where the pins went through due to the constant back and forth movement that occured when ever the wagon was used. Keep fighting it, you will eventually win. You might try hooking the rear of the gear to something solid, hook your tractor to the tongue, and gently pull on it while someone else works on that center reach with a hammer and a large pipe wrench.

Heat will help. Even a small propane torch. Put tension on it. Heat it up and let it cool, squirt some oil on. Tap it Repeat. It will come eventually

use a come a long, hang the back end of the gear in the tree so the front of the gear is suspensed a couple inches off the ground. spray the tube up real good with pb blaster, then tap the tube with a hammer to work the oil in it. you may have to keep at it for a few days to get the oil to penetrate thru, keep tappin and wiggling the gear till it slides apart. i did this with an old david bradley running gear.
