4020 rear hub bolts

Trying to loosen rear wheel hub bolts in order to remove wheel from the axle. Bolts must be rusted in tight. Have tried 3/4" breaker bar and snipe, as well and 3/4" and 1" impact. Can not get them to come loose. Heated the wedge on the inside of the wheel around the bolt threads, still no luck.

Anyone have any ideas on how to get these out!!??
 
Had a 12 foot cheater and two guys trying to get em loose on my
4020 broke the heads off everyone even after heating and beating
for a week straight after the heads were gone the real fun began
I spent another week beating on the bolts to get them out this
was on a daul hub dad made a special jig that I could stick a
bolt through like a punch to drive on the broken off bolts
 
Your problem is probably that the shank of the bolt
is rusted solid in the wheel not just the threads.
I have twisted them off even after beating and heating.
If your torch is large enough try heating the wheel area
where the bolt goes through.
 
I twisted the heads of a 60 wheel once, didn't take much, anyway I drilled a 3/8 hole through the bolts and then drove around with pressure on the push bolts and it came loose after a short time. I have a long bit to drill it. Do the inside bolts come loose?
 
Take your torch and cut the washer in half then drive out the
pieces. Then the bolt may be rusted in but it will not be
tight,and will be less likely to twist off.
 
3/4" bolt, 7/8" hole. The space fills up with field installed locktite. Cut all the heads off on a 4250 once and
drilled the remains out. First experience with a mag drill. Then I still had to rebuild the transmission.
 
D- is probably right, they do rust badly there try heating that end of the bolt up,,it will expand some and maybe crack the rust loose, let it cool back down before you put the socket back on...some times you need to use near every trick in the book to get them loose,,I had a bad one on a 4320 last week..
 
I have drilled them out with me holding the drill straight and my helper running a ratchet strap through the wheel and over the end of the drill,,kinda "Hill-Billy" ,,but effective...
 
Todd1969's idea is good, that way you can hit the heads with a hammer to shock them a bit and can try running them in a little with an impact.
 
Cut the lock washers out then use an air hammer on the sides of the bolt heads to shake the rust from between the bolt and hub. The vibration from the hammer will work the rust out. Do not use any lube for this step as it will make the rust sticky and not come out as fast. Dry it will look like smoke coming out around the bolt.
 
Thank you for the helpful advice! Might have to do like TimS said and use every trick for the other side!

I was able to get 2 of the 3 bolts out. Hammered on heads and then breaker bar and 4’ snipe was able to get them to move. Then impact back and forth to finally come out. 3rd one I twisted the head off with snipe bar.
Tightened up pusher bolts then threaded bolts back in loose and pounded on them to get wedge loose. Was able to air hammer on the broken bolt and it luckily slid through with the wedge.

On to the other side likely Monday!
 

I moved the wheels on an old 4020 LP a couple weeks ago. It always helps when the bolts come out and the pusher-bolts work.

Usually the star-wheels are stuck..and this 4020 was no exception. I could not get either star to turn...however if you can get a wedge pushed...you have it whipped. Can take the wedge opposite the star-wheel all the way out and let the tractor down a touch...move the wheel whichever way and jack it back up. May require an assistant...and just don't let the wheel/tire fall off the axel and kill ya!

Just saying...I've had Deere wheels that I never did get to move. I never promise the customer anything when it comes to getting a wheel moved.....Have sometimes had to remove an entire final-drive...tire and all to change load-shaft seals
 
I used your opposite wedge removal trick on a 50 a couple of days ago. The little pinion gear was locked up tight.
 
Has anybody had any luck buy soaking the bolts
and where ever you can get the oil to go in the
cracks in the wedges months in advance of the
actual day you want to try and move the wheels
