How do you replace the fan bearings?

[BluevanACD2005]

I am working my my engine rebuild, and am at the point of replacing all the little odds and ends. I am trying to replace the fan bearings, but am unsure of how to get it apart without breaking it. There are no obvious clips that hold the shaft in. I tried pressing the shaft out, but again did not want to break anything so I stopped.

In searched the forum and google but didn't find anything related to this.

Has anyone replaced these before?
