How to separate Fan from Alternator
 

Ok I give up! I managed to separate the shroud from the fan/alternator but now I can't separate the fan from the alternator. Any suggestions?

Stack up wood on either side of the alternator such that when you sit the alternator down so that the fan edges rest on the wood the backside of the alternator is a few inches off the ground. Place a couple of folded up rags between the pieces of wood. Lift fan/alternator up about 6 inches, drop, repeat as necessary. Gravity is your friend.

... and do not let the fan fall on a hard floor, as it chips easily!

failing that, try a plastic hammer. don't use a metal one. failing that, i drill a small pilot divot in the center of the shaft and run it thru with an airhammer and pointed bit. they vary in tightness from slip on, to frozen.

Obviously, the best way is to use a hydraulic press with two steel plates
adjacent the alternator supporting the fan. This is basically the only way
on 964/993 alternators without damaging them.

Credit the idiot that replaced the alternator for not using anti-seize grease.

i sprayed pb blaster (lightly) around the shaft too, in addition to what has been mentioned above.

Thanks for the suggestions guys. I'll try the PB blaster and wood block approach first.

It's off! Just took a little banging and a little PB. Thanks again. Can't wait to get the fan and shroud media blasted and powder coated. Got a quote for $85. Does that sound reasonable?

Sounds like a good price. The shroud is PITA to get blasted, so pay a little more if you have to to be sure they get it good and clean.

they're both a pain in the ass to blast, I won't be doing that again any time soon. Good bonding experience I guess
