Hello All. So I’ve finally set about getting my Emerson 14666 up and running again (the headwire is rotted through). I had a few questions to help get me started. This fan has a pancake motor without an oscillator, so first I was wondering how I would go about holding the rotor to remove the blades. Second, how would I remove the stator without hurting the windings or the housing? Thanks!

If there are some threaded holes in the rear of the motor case get two threaded bolts, 1/4 x 20 tpi should be the right size. Most hardware stores have these in the small cardboard drawers that contain all sorts of small hardware. Look through the threaded holes you want to use to make sure the bolt will clear any stator windings then snug down the bolts pretty good and try to unscrew the blade in the same direction it runs. If your fan is good to you it will be very easy, if not it may require some lubrication and heat. Use of common soft screws can result in the screw bending inside the motor and then the screw can't be withdrawn. Get these hardened cap screws but make there the ones you get have sufficient length of threads.

Steve, I actually bought all four screws in the picture per your advice on my Jr. restoration  . They helped out a lot with my 29646 too. However this is a different beast. No screw holes in the back except for one brass screw in the middle, hence my confusion.

I have a 14644 and a 1500 inside the circle of air cooling holes are 3 threaded holes at 10 2 and 6. don`t know if 1/4 x 20 or 10 x 32. looks like the screws would press against to rotor to maybe be able to remove fan blade. you may have to have three screws to hold the rotor from turning. maybe some other members with more knowledge on this can chime in. i need to do my head wire also.

I've never had this model and don't know if that single hole is threaded or not. I used to go through a vent hole at an angle using a smaller Phillips screw driver to hold the rotor with. Usually that worked but not easy.

Steve, it does have that hole as well as holes at the 3 and 9 position like the one in your photo. Would you suggest sticking a screwdriver in the top hole to try to hold the motor?

I didn't even notice the 9 and 3 o'clock holes. If there is a clear path to the rotor and you won't hit the stator, that's what I would do. You'll have to push in towards the rotor with the screw driver and feel if it is slipping or not. Sometimes there may be a small hole in the rotor you can contact to hold it, most times not.

Sean, I just checked my 14666 and I can see evidence of threads in the 3 and 9 o'clock holes. The fan was powder coated during a restoration by someone else and I have not taken it apart myself. However, I'm pretty sure 2 of the correct bolts could be used to lock the rotor and remove the blade. Just look carefully and probe around to make sure the bolts hit the rotor only. Please let us informed as I am also interested in removing & replacing the stator on Emerson pancakes. I know I've seen threads on this topic and recall the "hard part" is centering the stator with shims. I'll post any links I can find. -Edward Edit: Here's a couple of links that might help: http://www.afcaforum.com/view_topic.php?id=20951&forum_id=1 http://www.afcaforum.com/view_topic.php?id=20964&forum_id=1 Hope this helps & good luck!

The disassembly has begun in earnest. After removing the cage, I decided to take a look at he back of the pancake. Interestingly, i could see light from the window through the large hole under the air cooling vents. Turning the blades would cut of the light and it would soon return, leading me to believe the rotor has spokes that are accessible from the rear. I inserted a long steel rod which did the trick! I was surprised how easily the blade came off! Also, interestingly, my motor has no shims. I unfortunately have hit a roadblock. I cannot for the life of me get the nut off that holds the rotor on. My heat gun and oil have proven insufficient. Any ideas?

Another picture of the rotor. No matter what I do, I just can’t seem to get that nut of the end....

You some type of pliers on it, not a screw driver. Last edited on Sat Jul 6th, 2019 08:55 pm by Steve Sherwood |

Should I try to unscrew it with pliers or does it just pull out? Also, won’t that scar up the outside of the nut?

If I remember correctly, that should screw out CCW. I would use a small pair of water pump pliers or handyman pliers that have curved jaws to get the most grip on the bolt. No big deal if you scratch it up a little, you can smooth scratches out after you get it out.

Screw is probably reverse threaded. You're turning the wrong way.

That screw is not reverse threaded. But if you remove the brass nut on the back of the motor it will come out. In other words you can remove it by taking off the nut from ether end and it should come apart. There is a steel rod running through the center that connects both brass nuts. All you need to do is just get one of them off.

Also to help I use a wide chisel that I have ground down to be an extra wide screw driver. Works great to get these apart. Last edited on Sun Jul 7th, 2019 04:20 am by Don Tener |

As Don said it was not reverse threaded. I used some pliers and it came of pretty easy with surprisingly few marks on it! Now to get the stator out to rewire.

Well, I replaced the headwire, cleaned the innards, wired the headwire to the switch and managed to turn a running fan with a bad headwire into a prettier non running fan. Flipped the switch, nothing happened. Not sure what’s wrong with it, but honestly seems pretty typical for anything I’d try to fix.

What did the OHM's say? Check and re-check some more.. I got frustrated with an old GE fan once and sold it out of frustration but now I know what I did wrong...

Did you attach the wires correctly using the OHM chart provided on the wiring diagram page? What readings did you get on the stator?

Yes definitely put the ohm meter on the three head wires and publish the results. You should get three distinct readings. Label the three wires A, B, and C and give the readings for a to b, b to c and a to c. THe fan should absolutely work if there is continuity on the three readings. Then at least you will know if the issue is the speed coil or a bad stator. Let's hope that it is the speed coil. Stators rewinds are expensive.

So I cut the headwire to get at the stator again? I don’t have a wireing diagram nor do I have a multimeter. I simply color coated the wires.

Spend $25-35 at ACE and get a cheap meter for now. It'll OHM for you. You can use the switch ends of the new headwire or you can trial and error it too, don't cut the new one off yet. If you T&E it, be wary, one will run it backwards and may spin the blade off. The diagram can be found with a search or in the info section. I think there are 9 possible combinations, just use jumpers between the headwire and the switch wires with the switch outside the fan (be careful). The benefit of the meter is it'll tell you if you have good connections at the headwire. I seriously doubt you broke something beyond a wiring repair.

Did the fan run before you took it apart?

Sean, if this is the Emerson that is coming to the Museum, leave it and we'll get it running for you.

Yes, when I bought the fan it was running. The only reason I took it apart was a rotting headwire. It was literally held together by electrical tape. Also, Kim that sounds great!

Should not be a problem to get it running again.
