49 W9 rear wheel removal

I have 49 W9 that has been weighted to the gills on the rear wheels sometime in its life. We have removed about 1500# from the outside of the wheels and there is about 600# on the inside of each rear left. We can get the right rear wheel to come off but not the left. We have tried heat, port-a-power, tractor and loader, lots of penetrating oil, etc. Still will not budge. Finally we put the weights back on the inside of the right rear, for balance, but would like to get the left off to make easier to move. Any suggestions would be appreciated.
 
Sometimes they don't come off. I moved an I-9 wheel several inches with a pair of 20 ton jacks but no further. I am now faced with the prospect of removing the bull gear and detaching the axle housing, axle, and wheel as a unit. I will then haul the assembly to a shop with a 250 ton press. That should do it.
 
you can try building a puller for it. you'll need a stout steel beam, some 7/8 or 1 inch all thread and a large bolt and nut for the center of the puller. drill and mount the large bolt thru the center of the beam, then drill the ends so the all thread can pass thru the beam and thru the wheel weight mounting holes in the cast hubs. tighten up the all thread, then start tightening down the center bolt to put pressure on the axle stub. keep spraying banging and heating and tightening the center bolt. you may get it to pop loose. like wardner said, they are a devil when they are froze on.
 
Go with Glennster's idea. I must have been confusing W-9 with W-6 rear ends. W-9s don't have detachable axle housings. You would have a hard time finding a press that could handle the entire rear end of a W-9.
 
Dad and I wrestled with the same thing on a WD9. We finally built a puller that allowed a 20 ton jack to be approximately 18" away from the heat and rigged up four tiger torches, applying heat to the inside of the casting. The paint had long since burned off the hub when it decided to give up with a heck of a bang and started moving about 1/2" inch at a time. We darn near used 100 lb. bottle of propane on the job before it came off. We were a bit concerned that it may overheat and weaken the axle, but although it cooked the seal, and the grease was smoking and bubbling real good it didn't get hot enough to burn.

After reading your post I went up to the shop to see if the puller contraption was still there because I might need it when I pull the hubs on my WD9. Couldn't find it. Which translates into: I'll need it.

They can be a bear.
 
No, you're right the '9's (Milwaukee built) don't have removeable axle quills like the smaller tractors, but you can separate the rear "banjo' housing from the transmission housing and then take off the bull gear retaining capscrew and pull the axle and outer bearings and seal out of the housing and then get it with the stuck wheel center intact up in a big arbor press and "punch it out". Might have to go to a shipyard or locomotive shop to find a big enough press....(not trying to be funny).
