For my Birthday I got myself a beautiful almost mint, single owner 77648 mid 50's brown emmy. And for that, I paid a little extra and thought it was worth it. It ran beautifully and strangely quieter than my bedroom 648. but had the slightest of ticks that sounded papery.  Figured something was stuck through a vent hole and would take care of it upon tear down. It's my third single bearing emmy, but fourth tear down (sis caught the bug..) so the routine is known and has never given me trouble.... Until now.

Got the cage and the bullet off and no holes in the rotor to wedge into.  Oh great! never had one like this. This will be fun! :shock: I notice bits of the rotor that stuck up it looks I could possibly use to leverage a screwdriver on to. No go. Kept slipping and I didnt want to risk stabbing the windings. Went with the bolt method, went in just fine and what I thought was enough clearance between windings and the bolt. Cranked it down to lock rotor in place. Gave the Blades a twist and CRUNCH, the sound of Expensive. My heart sank and I was devastated. The bolt bent and went straight through windings. And the blades STILL didn't budge!  Now it just hums and will run on high, weakly, with a spin. So now it's a slightly useful paper weight. I am a mixture of sad, upset, and frustrated. :cry:  And I just felt I need to vent my horrendous actions.

If you're near St. Louis, Any help with a stator (and now a rewire) would be greatly appreciated. I really don't care for rewiring headwires. I have spare clothy wire and shrink tubing for a redo. Whether you have a stator and/or can help me swap it that would be flipping amazing of you.  I can come to you, or you can come to me, I don't care. I'm willing to drive a little.  Preferably a weekend since I work weeknights. My facilities here are a bit lacking now that I think about it, so the former is probably better as I generally just work on the floor.  I could use help getting the danged blades off as well, but that would just be an excuse to hang out! I'll also consider shipping the housing and stator if I can get the blades off beforehand. Also whatever other options  pop up... 

I'll toss this into the BST, but while I'm here If anyone has a spare stator or even a whole fan in good shape you're willing to part with, that'd be great. I'd consider a rewind if it wasn't too horrible and someone here could do it. But I'm gonna guess it probably isn't financially worth it.

The reason why the bolt bent on you was because you didn't use a stainless steel screw, if you would of used a stainless steel screw it wouldn't of bent like that. 
Anyways your best bet is to post a want ad in the BST section of the forum for a replacement 77648 stator. There should be several members on here with some of those stators hanging around in their parts bin they'd be willing to part with for you. 

Tom Newcity comes to mind.

Thanks, Levi. BST was the second thing I did, right after the story of treachery.The bad part about the bolts? I had both in my hands, stainless and regular. Did a quick and now obviously embarrassingly poor job of searching on the subject of strength. And also thinking what I knew what I was doing without asking for confirmation.:idea

Lesson learned. And the literal headache to go with it. :hammer:



On a positive note, It's getting the full treatment now when i was originally just gonna leave it.


Edit: Positive note

Good to know.  Yeah,  I actually have a 1955 Emerson 74646 AS Hassock fan that I got from a friend recently who said it wasn't working anymore,  which I managed to get it going again,  but now when I tried starting it just now it started making a loud grinding noise that it wasn't making before,  so I too have some troubleshooting to do as well.

Actually grade 8 steel bolts are better than stainless. If you were closer to PA, I’d be glad to help you to remove the bad stator. Hopefully a local member will respond. 

Heat applied to the blade hub should loosen the old oil that’s binding it currently. Just be careful how much force you apply to the wings as you can loosen the rivets or put them out of clock. 


There’s a leather washer immediately behind the hub. Often the old oil creates a sort of glue there. You can also dribble some good penetrating oil on the hub so it runs back there and soaks the washer. Also make sure you’re trying to turn the blade in the SAME direction as it normally spins. Darryl Hudson has the replacement leather washers. You’ll need a new one for reassembly. 


I hope this helps you. Emmys can be frustrating to remove the blade.

 This is the fourth single bearing emmy I've played with. I have a couple, and have worked on one for sis when she learned how awesome they were. This one by far has been the most stubborn and still have made no real progress.

I can't find any grade 8 bolts, or anything aside from stainless in the correct thread and that was going to a couple old school well stocked hardware stores. This one isn't 1/4 20, it's 10 32, which makes it a bit more interesting to pull off as I've only found that size in a phillips head screw. I went on ahead bought the SS version, and while it didn't bend nearly as badly, it kept binding up in the threads after it was tightened and it started slipping between the rotor and the stator.  Rotor still slipped. Obviously It didn't seem like a good thing, so I backed it out and am still a bit clueless.

On your recommendation, I also put some penetrant on the front of the hub, aiming for the leather washer and hoping to make some sort of impact.. Thank you for the idea!

 I unfortunately don't own a torch to heat up the hub or know anybody with one, otherwise i'd consider that. How much heat can that paint take, anyway?

Update: Got the *blanking* blades off. The amount of crud holding them on was crazy... So, one problem down, a few more to go!

I managed to pop the stator out. That was a little easier than expected aside from some crunchiness. Everything is still connected, though. Shaved a bit of insulation off and Unless there are others broken and hidden, I think this is the culprit. Amazing what one little wire can do.

I use an old black hardened set screw to remove blades. Stainless will bend if you really force it and (trust me) it doesn't take much bending to make it almost impossible to remove the bolt.

You should be able to find a 77648 with a buggered blade really easily to salvage a stator from. If you had a TR, I could provide one. I have a few of those as parts fan but I don't believe they interchange.

solder that one wire, you've got nothing to loose at this point. Lane where do you get a hardened set screw 3" long? nothing with any grade strength is availble with full threads.

I've found Grade 5 & Grade 8 All-Thread at a bolt supply house - Cut to length and install a Wing Nut or 2 nuts jammed together. I also sharpen a small point on the end to grab better.

I'm actually quite crap at soldering. Hands arent steady. But with nothing to lose soldering actually worked! Tugged at the connection a  little to be sure. Then I coated everything in liquid electric tape since I don't have varnish. I don't really trust it, so just in case I'm still going to be looking for a new stator. And now the switch/coil is buzzing on low, and it was not doing that before. Not the cap.
I'll keep an eye out for grade 8 elsewhere. I actually nearly ruined the rotor with the stainless steel one. Luckily it's fine.

Thanks everyone for the help so far!
