SOLVED! ( ... or almost ...) How to safely remove the impeller from a Grundfos UPS32-80 180?

No idea if these will be helpful? This is one I destroyed whilst dismantling (was used in a marine fish tank)

Really need the next page to put parts to numbers.

It wouldn't be as simple as this would it?

I thought I observed that the bearings are in the "sleeve" of the stator so, if the shaft of the "old" is fine, it is very likely that changing the rotor from the "old" to the "new", everything will be solved . I'll wait for spring to come ... or until the "crack" occurs.
Thanks a lot,

This is what I was afraid could happen, thank you, SpecialK, now I know what I can't do.

Thank you all very much for your suggestions, comments and images, now I have all the necessary information to know what not to do and what I can try to do.
Merry Christmas and a Happy New Year, if we can say that.
