I bought this fan earlier this year and just decided to restore it. Overall the fan is complete but has lost about 90% of the paint. The problem I have run into is that I cannot remove the rotor because the stator windings have distorted and hardened not leaving enough room to slide the rotor out. It is 1/4" too small. I can spread apart some but not enough before I hear the wiring varnish cracking. My only thought is to apply some heat and pressure. Any ideas?

Warm the windings with a heat gun and they may become more flexible. Many were asphalt impregnated and the heat will soften it. 

If not, you’ll have to clean the bearings with the rotor in place. It’ll be difficult if you
Need to remove the stator to replace the headwire however.

Edward, that looks like a replacement winding; which was accidentally made a little bit too small. The original one had enough extra length to it so that it would naturally lay "bowed out" around the rotor bore.

You may find that from the front, the rotor will slide out. Maybe try taking the front cover off and see how the winding is arranged on that end.

It might be a good idea to make a new winding anyway, since that one has been cured in place and then moved until you heard cracking noises.  Just saying......

I was assuming it was the original coil but anything is possible. This does not have a front cover, My first thought was to remove stator and pull rotor from front but there is even less clearance in the front.

Pretty common for that to happen. Try what Lane suggested or work around it if possible.

I did heat it up with a hair dryer and just got it to move enough to get the rotor out. Looking at the stator I can see that is had been rewound at some point.

If you need a replacement stator I might have one from my old AOU that I ended up using for parts that I could send you, it would just need to have the windings revarnished and retaped with new friction tape, but as far as I know, when I tested it with the ohmeter setting on my multimeter the stater still tested good yet.

Hi Levi, is that stator you have from a 2 Star fan?
If so, is it a 12 or 16”?    Is 3 or 4 wire headwire?

style="background-color: rgb(255, 255, 238);"Thanks, I think mine will be OK, OHM readings seem good. If yours is a 3 wire Lane is looking for one.

No. The fan I had was a 1929 model AOU Form V4 if I remember right, and it only had 2 wires coming out of the stator on mine, and mine was a 16" model. So unfortunately mine won't work on Lane's fan.

Levi, I may be interested in yours. Please check if it might be a 3 wire. You can pm me so we don’t hijack this thread. Thanks

The windings are fine as far as operation. Just got it back together and running.
