Update: still stuck, but I've learned a couple things. With the gears removed, at the point where the inner tube should slip out of the outer tube (but mine doesn't) I find I can turn the shaft easily. Smooth and nice. I figure that means the inner mechanism, the worm drive and all, is in good shape.
Because it's no longer held in place at the top (and no longer trying to move the stuck inner tube) I can crank it down about an inch, so there's free space between the top of the inner worm drive mechanism and the welded plate that serves as a stop when everything is properly assembled. Which in turn means that I can tap on the foot end and move the inner tube upwards about an inch. Then crank at the top again, make room, tap at the bottom... and so on, gradually compressing the whole rig, pouring in penetrating oil as I go. I'm hoping to free it up with the movement and the oil.
So: I can move it in, but can't pull it out. I'm thinking of trying a come-along on the pulling end if it stays stubborn. Maybe donate it to a tractor-pulling competition, LOL
For what it's worth, the inner tube -- the 30 inches or so that I've had out -- is clean, smooth, in good shape, no rust. That outer tube must be a mess inside.
