Question Stuck Spline Shaft

anyone have any suggestions of how to remove a cast hub and spoke wheel off of a six spline axle shaft? The tractor is a 1929 Twin-City KT, So far we have busted the outer flange while trying to pull it off with a 10-ton porta-power, which can be welded. we cut a slice down the shaft, still nothing. lots of heating and cooling..dual torches, dry ice. Finally we have the entire assembly off of the tractor...bull gear, axle bearings, cover plates. Now that we have it ALL off the machine, what can we do? We're afraid of using a press because the bull gear cover plate is too close to the hub and would only be able to press against the plate and not the hub. Any suggestions would be greatly appreciated,

Question Re: Stuck Spline Shaft

What are you trying to save - the Flywheel? the Shaft? or both? How is the wheel placed on the shaft to begin with-is it a press fit? Does a bolt clamp the wheel to the spline? Does a set bolt anchor the spline to the hub by direct pressure? Interferance fit? A lot of questions, I know, but we need to know answers before we can help you, as different techniques are used depending on your answers to our questions too!

We got it apart! We had the wheel on its side and up on blocks. Packed the hole in the end of the axle with dry ice and alchol until the hub got frosty. Drove on the axle end with a two inch brass bar and a sixteen pound sledge. It fought us the whole way. What was holding it on looks like old grease that had turned into a black carbon cement.

Reading about your ordeal makes me wonder if you may have encountered an old time "fix" for a loose spline joint. You'll have a better idea after the parts are cleaned up.......
