i can buy the entire fan for like 35 bucks on ebay

 

74demon's mentions, parts are available, so you might be able to just replace the blades.
In fact, here's an after-market if you want to go 'mambo' on it. A bit pricey though and
yours wasn't listed. I bet they make one for the F4i, you'll have to talk with them
though, to be sure. There's a contact on the page, if you're interested.

I'm sure there are less expensive alternatives, just thought I'd give
you the option. ;-)

Usually, you can grab the fan blades to keep the motor from turning while you loosen
the nut on the shaft. That's gonna be trickier, if you do go for a blade replacement.
After looking the pics over, probably not worth trying to save. I bet you
can get a full fan replacement on ebay pretty cheap. Do a couple of searches and
you'll know pretty quick, what your best bet is.

At least it'll go back on easier, since you've done the hard part.

Good luck, which-ever way you go, Ern
