OK, you'll have to humor me as I'm still getting up to speed on my fan terminology. The part in the head that the head wire connects to is the part in question here. On my fan I've somehow managed to get it moved far enough forward I can't get the screws in the back to grab it. It's real real snug and I can't seem to easily push it back. Anyone have any suggestions on how to accomplish this safely?
I'll have pix up this weekend of it. It's a semi restore. I've repainted it, stripped the blades and cleaned them up. The paint job is a bit different, so I'm curious to see what is thought of it.
Thanks in advance for the help and thanks again for all those who have helped me in the past.

Aaron,
Sometimes the screws that go in the back or front are longer than the front or back screws depending on which end of the Housing the Stator installs in. Also, most GE's I've seen have a some formed sections or detents that prevent the Stator from going too far forward.

| Aaron, the part you refer to is called the stator. First, you want to be sure you're putting it back in the same position, the holes line up every 1/4 turn but you want it to be the same as when you took it out. You can put a very thin film of oil on the inside of the motor housing to help it slide in. After that, you could turn it, stator facing up, and lightly tap the whole unit on a block of wood and let the weight of the stator help get it back in. (I use the same method to get the stator out. Put a cloth on the block to protect you nice new paint) Also, keep an eye on the head wire to be sure its not getting pinched as the stator slides in. I've only done a few of these, but this method has worked for me every time. I hope this helps. Last edited on Fri Jun 19th, 2009 08:00 pm by Ralph Bliss

Thanks for the help all. Mine had just come forward a bit and I couldn't get to it from the back with the screws. Some time away from the work bench cleared it up for me. A hammer and a leather hole punch(?) plus a few gentle taps pushed it back where it needed to be. Also, some of the screws were a bit longer, 1 thread or so, so good suggestion there.
In regards to the stator, any recommendations on what the inside the motor spins through can be cleaned with? And the motor too. Mine's a bit "gummy" feeling.

Just use some electronics cleaner or brake cleaner on the rotor and inside of the stator.

Since I'm on a roll here.....
How much front to back movement should the motor have when everything is assembled.
Without the fan on there's a bunch of movement and when I run the motor I can hear that something's not quite aligned. Before i had this disassembled I'm pretty sure it ran fine until I engaged the oscillation. Then it would grind to a halt. I know this is pretty vague. I'm about to go grab some cardboard and set up on the kitchen counter while I watch a handful of kids play with some toys.

if you're talking about the rotor shaft, front to back play should almost none. You can install fiber washers to take up the extra space. The can be bought online from McMaster-Carr

That's exactly what I have, about 1/4 inch. Where to these washers get installed? It looks like when the motor turns, the shaft slides back and the back end of it rubs on the outside wall of the gearbox.

| The washers go on the rotor shaft inside the motor housing. With that much end play you may need 1 or 2 at each end.

From seeing another post, it looks like I need 3/8 ID washers.
Do these look right?

25 should last me a long time as I don't think I need more than 2 here.

Aaron, Felt washers are fine but, I don't think you want to use that thick of ones and you'll need a fiber washer at each end of them. McMaster-Carr carries Fiber Washers that are only about a 1/32" to a 1/16" grey and red. I think these will be what you want instead of felt. Remember the rotor has to be centered in the stator.

So I'm making a "sandwich" with a felt in the middle surrounded by fiber on each side? Just want to be real clear here.

And as I re read what you wrote, grab my ears and pull real hard, it all comes clear. Fiber washers, not felt. Got it.
