... You could just pull the fan straight off. Make sure not to oval the hole in the fan. JB weld it back on, like Vinci did. Seems like it worked. Worst case you need a new motor, which at this point (if you listen to these people) you already need one. Take a gamble on it.

I saw
a video on youtube of someone servicing a rainbow......and instead of removing the fans, they took it outside, taped some things up, and turned it on, poured water in the shaft area and the water shot out the back (this is with it running)...He clearly stated in the video that people watching this might get pissed, but someone he knows knowledgeable in rainbows taught him that. I guess pouring water through while it's running somewhat cleans the fans. I don't know. I sure wouldn't do it. But it looked like it worked.

if the upper bearing has come apart it is highly likely that the bracket has been oblonged or Hollowed out meaning that a new bearing will not snugly fit back in place. As stated in replies above it is advised that the fan not be removed and at this point you should get a new or used motor to stick in there as these motors are made to have the minimal done to them... i.e. lower bearing, cleanings and carbons. as for fans. When properly cleaning a rainbow the motor should be torn down and the fans should ALWAYS be properly cleaned to ensure a smooth running machine. Improperly cleaning ( pouring water through a running machine) is dumb and will result in nastiness growing in the machine and also a risk of burning out the board. If you feel that you cannot fix the issue yourself, privately message me and I can see about a rebuild for you at a low cost since I am a rainbow service tech, or take it to your local service center. The JB weld on the cooling fan is by far the dumbest thing I have ever encountered and I have had rainbows come in with fans that have been JB welded into place and they wind up ruining the motor from coming off of the shaft.
Just 2 cents from the technicians point of view.

Rainbow E2 Single Speed Motor Cooling Fan Removal
is fairly easy. I performed a refurb on one back in September 2020. Removed and replaced the fan (and bearings) without issues and the owner (Thomas) has been running it since then. I'm saddened that some "experts" don't understand what "press fit" means.
If I wasn't so pressed for time, I also would have used JB Weld as well.

Yea - I remember you really are against removing the fans at all. I remember you said it makes it worse and it's best to not take the fans off. I remember because a couple of years ago when I dropped my rainbow off at the dealer to have them fix the control board, I left my #. He called me back and I asked if, since he had it there, if he could take the fans off and clean them..He told me they didn't need it. I asked him to do it anyway and he didn't. (LOL) I remember you saying that it's a good thing he didn't because taking the fans off can cause more troubles. The only thing is, I've seen many many people take fans off and clean them and never mention it being an issue.

"Experts"
Exactly. Look. If you're a novice, and everyone's telling you just to buy a new motor... just TRY to fix your old motor. Worst case scenario, you screw it up and need a new motor, which you already needed, so no great loss. And best case, you fix it just fine, and saved yourself the cost of a new motor.
And succeed or fail, you learn something in the process, making you a better human being.
