Hello, I recently acquired a spare motor for my Silverado.  It was sold as operable, but it arrived with the outer fan housing dented to where it slightly rubs on the fan.  Ordinarily I'd just disassemble, remove the dent, and reassemble, but the auction images didn't show that the fan housings are badly rusted.  I was able to separate them from the front bearing plate, but I likely will destroy them separating them from one another.  I've done it before after days of soaking in penetrating oil, but these are much worse.  I tested the motor using the fans and fan housings from an AE motor I'm servicing, so I could be sure it's in good running condition before I request assistance here.

I *could* just leave the motor in a partially-assembled state until I need it, and then pull the needed parts from the dead motor, but I'd rather have this one complete and ready to go.

I will appreciate any assistance you can provide.  As an aside, I think it's so cool how these and other parts interchange in motors that were made so many years apart.  This should mean that any motor from the AE through the early Silverado could be a donor.  Please correct me if I'm wrong on that point.  The stationary fans are different, but the motor runs fine with the AE parts.

If you can help, please email me at the address in my profile.

Thanks,

Joel

Unfortunately, I just ruined the armature of the AE motor.  Instead of the usual aluminum sleeve behind the rear fan, there is a washer that should've just slid off of the shaft, but wouldn't.  I bent the shaft trying to remove it so I could remove the front bearing cap.  This explains why a former owner greased the heck out of an obviously bad bearing and left it in place.  I had no such trouble when I did the same repair to my working AE.  This was to be a spare motor, and it wasn't in the best condition, so I don't feel too badly.
