Disc Harrow old disc repair

[cedar21]

The shaft is square (other than where is has been rounded by the discs after it seized up). It runs through a round pipe that is on the inside of the bearing. I am not sure if this is how the disc was made or not, though I have not seen wood bearings that are square on the inside. So far, I have not been able to remove the one bearing I have tried to remove. I have tried to pound out the pipe in the middle, but cannot get anything to move. Might have to resort to a cutting torch.

Agri Supply has lots of parts to help you out

Agi-Supply does not seem to have the outer part of the bearing that goes around the spool for a 1 1/8" shaft, and that is the size I am trying to find. I also am not sure if there may be another sort of bearing that would work. Just looking for some information and ideas from someone more experienced than I am, as this is the only disc I have tried to replace bearings on.
