Here is what the steering parts look like in the Illustrated Parts List:

As you can see, there have been some "tenant's improvements" brought about by a previous owner. The purpose seems to have been to space the steering bevel gear downward, so it would mesh properly with the matching gear sector on the cross-shaft. I can't tell from those pictures why this was necessary. Possibly the bracket that locates the bevel gear has been moved up, or the cross-shaft has been moved down (or even both, who knows?). However, note that the Tractor 5, Tractor 8, and Tractors 10-11 used three different designs of vertical steering shaft, so it is possible that a worn-out shaft has been replaced at some point with one from a different model tractor. This is not a problem in any case - if necessary the improvised spacer on the shaft can be replaced with a proper one, without making other changes to the steering.

To remove the steering column, it clearly cannot be moved upward because the bevel gear is permanently attached to the shaft. It looks to me as if the cross shaft which includes the matching gear sector has to be removed, but let's verify that. Can we see some pictures of the mountings for that cross shaft please? You will have to remove the broken steering wheel, probably with a gear puller.
