I may have the wrong motor tag but my fan is a GE AOU with a cast iron base and motor housing. Do you still have the cover I need?

If your motor is cast iron and not stamped steel the gearbox cover will be different and made of cast iron. If your motor is stamped steel it will have a pot metal gearbox cover. Form AF2 is for a stamped steel motor and base. Does a magnet stick to the cover on your fan or to the gearbox itself?

The easy thing to do would be to post a photo of the back of your fan with a clear shot of the gearbox and cover along with the oscillating disc under the gearbox. I think that would tell people what you have and what you need. One picture replaces 1000 words (and a lot of guessing).

ok I will put a picture of the one I have today before I send it out to you. how's that?
Steve I dont think weather mine came from a steel AOU to a cast iron type didnt the oscillating gear box's remain relitivly the same size? why change it if it was already perfected to oscillate?

Actually no, Peter. Apparently it does make a difference, I got a parts fan AOU once thinking I could use the cover among other parts off it at the time that I need and the cover was too big. I learned the hard way I guess. Yes, please post a pic of your cover.

Adam, Jeff Arnotes gallery fan is a FORM AF. It has a stamped steel base and motor and a pot metal gearbox and cover cast separately from the motor housing. The oscillation wheel is also pot metal/diecast zinc on stamped steel GE motors of the late 20s and 30s. Prior to the stamped steel motor (first steel motor was a FORM AE in 1925 and those had iron bases still) were Forms AD (1924) and earlier which had cast iron motors and bases. These used a brass oscillator wheel and the cast iron gearbox was cast as part of the motor housing. The cover was also cast iron and I would be surprised it it would fit a pot metal gearbox.

I guess it's possibly you could have an iron motor on a FORM AF stamped steel base but GE didn't make it that way. What I am inferring is that you need a pot metal cover for a pot metal gearbox and a cast iron cover for a cast iron motor/gearbox so, if the motor in your fan has been "backdated" to cast iron, you will need an iron cover.

So you think the motor plate is wrong? How do I properly date my fan so I get the proper motor tag for my specific fan?  Because mine has the same Cat. # on the tag as Jeff's but its for sure cast iron, the fan weighs at least 10 pounds fully assembled.

Steve, I'm gonna try to upload some pics of the inside so you can hopefully tell me if its cast iron or just heavy pot metal

Need more details to tell what Form you have. Looks cast iron to me. If it had rubber feet like it looks it did it would be a 1920 model if the oscillator disc is cast/machined brass and would be FORM V (V5 maybe). If it's a star fan it's earlier. GE used the same catalog number for close to 25 years (75423). Many of the parts were nearly identical for many years also so we have to see the sum of the parts to narrow down the year and FORM letter.

Hey why don't you tell which one it might be I have 2 of them. and Adam why don't you measure how many inch's your gearbox is accross to see if we have a perfect fit.

the one I have is just around 2 1/2 inch wide and the other one is 2 3/8 wide also but both have the round knob.

Steve, when I got the fan it came with a base plate attach and I don't how the lever switch would attach to the base without the base plate and also I noticed there is numbers in the casting under/inside the base. Do they mean anything?

The numbers cast into your base is probably a pattern number of no significance other than to be able to match up an identical base. It looks like you have a cast iron base and stamped steel motor which would be 1925-26 and should be FORM AE unless there might have been a little overlap in the change to the steel base.

If the housing is stamped steel how come the motor came out so much easier then it did in my westinghouse? I thought stamped steel was harder to work on, thats what was making me think it was also cast iron, that and it seems alot heavier then my westinghouse even with the motor out

If you copy the picture, enlarge it, and lighten it up you will see the Motor Housing is in fact a casting. That's why the Stator came out so easy. The Base is definitely cast iron.

John, I don't think so on the motor. I just checked my late AOU FORM AS1 and the motor housing is all magnetic and NOT cast iron so it must be stamped steel. The oscillator gearbox is diecast zinc and non-magnetic and cast separately from the motor housing. The base on my fan is also magnetic stamped steel but the base on Adam's fan is obviously of the cast iron construction. But I bet his motor housing is magnetic and not cast iron leaving only stamped steel as the possibility. Cast iron AOUs have the gearbox cast as part of the rear motor housing instead of separately cast as with the stamped steel motors.

Enlarged picture of Adam's Motor Housing. It looks to me to be cast or a very thick "stamped" housing. Also, the last time I checked, cast iron was magnetic but maybe you have a different cast iron.

Maybe Adam has a motor from a Hunter AOU style which was made of pot metal sometime during the 20s and maybe 30s. without a whole fan and good photos it's hard to tell what's what.

I agree that motor housing does look like it's cast or something.

An easy way to tell a stamped steel GE AOU motor is to look around the periphery of the motor just forward of the two upper, rear motor screws. There will be a pair of punched dimples to either side of the screws about 3/4" forward of the rear screws.

It's very easy to tell cast iron from stamped steel AOU unless things have been changed around which could be the case on Adam's fan. I just don't know exactly what he has.

Just my two bits,
It looks to me like Pot-Metal front and rear motor housings with a cast iron center housing? Doesn't look like any GE I've ever had apart. And the base looks cast but as Adam said before, I see NO screw holes on the inside of the base to hold the switch body to. This may well be what Steve has mentioned, a Hunter and not a GE at all. And as we all know, you can't use Hunter parts on a GE or vise-versa.

Adam,
If the motor and base housings are non-magnetic you probably don't have a GE fan. Probably Hunter. Though Hunter and GE fans were the same, other than the badging, in the teens they weren't in the 20s and later. If the oscillation wheel or disk is pot metal and not brass and is not trumpet shaped as on the post 1924 AOUs then you do have a Hunter or some other "mutt" would be my best guess without seeing the fan in person.

This is one pitfall of buying fans that have been messed with or messed up or are missing parts, have broken parts, etc. By buying complete fans in good running condition you usually will end up with a nice fan or one that can be restored to your taste and, most likely, at a lower cost in time and/or money. But, if you love the challange of making a "parts machine" run again and look great, go for the problem fans.

Steve,

 I checked both the base and the motor housing with a frige magnet and it doesn't stick to neither of them also I checked the motor itself and it looks like there are 2 punch demples where you said they would be (assuming I understood you correctly)

I'm wondering if I could have this fan? "16"" SB/SC
Century
1936
The Brandts"  because it looks really similar although the "trumpet" shaped oscillator is brass and not painted but I recently learned on here that some brass was painted

Adam, you could have that or a similar HUNTER (not Century) as shown in the Hunter gallery. The oscillator disc on that fan could be made of pot metal. It's similar in shape to the brass (painted green) discs of the 1920-24 GEs but is slightly different in shape when compared side by side.

Without seeing your fan all together I don't know if we can tell what you have. Even together it may be difficult is some parts have been changed.

Steve,

What parts of the fan do you need together in order to properly determine what fan I actually have? I'm assuming base, motor housing and hoop handle..but anything else? I hope you don't need the motor in the housing or anything like that because I'm not close to putting the motor back in.
