So, after about 18 months of absolutely no work on fans or my old cars I decided it’s time to get back into things. Naturally, I picked a very simple uncomplicated fan for my project of the weekend. This is a GE Collar Oscullatir I’ve had for a few years, and started work on a while ago. Rick Huckabee rewound it for me and Kim Frank had some of the missing pieces to make it whole. Now it’s got a beautiful coat of black epoxy on it and I just need to Figure out how it all goes back together as it’s been a while since I took it apart! I’m sure I’ll be asking the experts for advice over the next week or two!

Thanks Lucas! I'm going to attempt the reassembly but if I run into issues, I'll keep you in mind!

Larry,
I don't know if you did pictures during disassembly, but if not or if they're not complete, I've got a bunch of them showing the relationship of parts at various points of disassembly.

Thanks Jim,I do have lots of pictures, and this thread on the forum   (http://www.afcaforum.com/forum1/47742-1.html) has some great detail pictures as well, but I'm sure a few more wouldn't hurt! 

My issue right now is how to remove the spur gear without damaging it! It's press fit, but it's on there tight! And being pot metal,  I know if I pry it too hard it'll shatter... any tips?

Both spur gears shouldn’t be removed as they are pot metal. If the one connected to the motor housing is there (and not broken) the only way to remove it is to cut the through pin and make a new one to replace it

Should the gear in the motor housing be fixed in a stationary position, or does it rotate?

If it doesn’t rotate that’s a bad thing. It’s meant to rotate against the spur gear in the neck. It stays constantly meshed and the ring on the lower spur gear acts as a clutch, locking in place, as you twist the brass neck.

That's what I thought... this is stuck solid. Guess I'll soak it in some penetrating oil to see If it will loosen up. I don't want to use heat on pot metal.

Looking through an old iPhone and found a picture of the collar oscillator when I first got it back in June 2016. I didn't remember it being this bad!

Wow, that's a sad sad fan. I love this fan. Got one from an AFCA member that was in good shape and restored it. Runs quietly and smoothly. Too bad the gears are made from pot metal.

Making parts since yesterday....  gonna be a nice smooth oscillator after replacing half the mating parts:clap:


























And peek-a-boo. A place to oil your front bearing and gearbox.  Just have to remove the cage and blade to do it...

Made some pretty good progress today but had some setbacks. First I was going to check the bearings and nose to the rotor. Bearing was bad. The nose was worse, like .020 of slop. 
I don’t personally know Larry but he is a man after my own heart. I told him about drilling through pot metal and the chance of failure being high and catastrophic. I sent him a video of the nose flopping around on the rotor and having around 1/4 inch play when tipped back and forth.  I’ve sleeved one before that was similar. I told him mine sounded like an aluminum can blowing down the road and it wasn’t a usable fan, even with the new tight gear and linkage. So without hesitation he says go for it. A man of my own heart. You want a working fan that runs flawlessly. And with a little luck we can make that happen. I might write this one up in the mag. After I saw the before I was like hold on to your seat dude, this could be a bumpy ride.





First drill. No turning back. Ideally I’ve found .060 is a good target for a bushing as a minimum. That gives .030 per side, anything thinner and it starts to deform while being pressed in.  So that’s my target. Step up drill size by drill size until I’m there


Second drill went fine too. Ok smooth sailing. Third a little grab, and fourth,  bad things.  Hit an air pocket and I thought all was lost.  Nose grabbed the drill and I was quick to shut it down. Then ran the drill in by hand and applied pressure while running the drill in reverse








Hard to see the big air pocket from the pics but there were lots of air pockets. At any rate I got .020 more than what I had. So .040 bushing. Then started looking at the rotor. Holy crap that’s .010 off from wearing unlubed all those years. How do I get a tight fit if the bushing slides on and then rests in a pocket?  Take it to the lathe






















All things well with the world, minus the tiny bit of break out I make the bushing








Check the nose for fit








Good and tight for a press fit


Try it on the rotor and run it in






Left a little lip and split the difference at first. Coming down to the worn diameter would mean the blade would be off slightly. So I got as close as I could between nose and blade slop with some Emory cloth and a file the rest of the way. Pressed it in and viola!








Didn’t even have to touch the paint up. Eat your heart out Kim Frank:P







And yea I’m sponsored by JB weld:up:  more to come

Great work Lucas! I was nervous about that procedure and very happy it worked out!Hopefully, no more major surgery will be required! :D

Thanks guys. Always a pleasure to bring you along for the ride. I take pride in making collars better that they were made originally. Most of the parts were designed with an interference fit and need to be massaged to come together. I’ve tried to machine down to the final dimension and it ends up not fitting tight enough for my liking. That’s why I personally run them in. As shown below I had a bad interference issue and without a keen eye and feel it could have caused major issues
So the story of Larry’s fan continues. First with a fresh rear bearing




Then a shaved down nut for the back of my improved design for attaching the link to the spur gear.  That completed the linkage assembly. 

I assemble the nose components back with valvoline grease. I like it better than redntacky and toss up between that and white lithium or synthetic lithium like stay lube. 



Nice thick layer on everything in there. Then the brass cover and  worm gear. The bolt that holds it in place is a left hand thread. Lefty tighty. And don’t forget a washer in the nose. Use lots of grease to keep it there






Then filing on the pot metal nose to get a smooth fit to the motor housing. That is never fun.  Try to avoid a paint mishap while working a micro flat file




Next is a full nose and assembly hand run in through a full sweep using the rotor to drive it through its paces










Actually ran into an issue with the link not being trimmed and it started to rub the rotor. Back apart and back to the grinder. Just a small amount hanging outside the shoulder screw was too much




Next steps is to put the back cover on with the bearing snug but not tight. Put a blade on the rotor a little lube and hand run in by turning the blade. That breaks in the full assembly and bearing surfaces. Then motor and check the link clears the windings. Finally power and run for a while. She is gonna be pretty

Looks great Lucas! This is going to be a nice fan!  It'll have a place right next to Kim Frank's old three speed coin op! :D

Next steps on this fan. Test fit the stator in the housing and proceed to file the 4 feet until it slips in there with slight pressure, but can still be adjusted to align with the bolt holes perfectly. Then a fiber washer on the rear of the rotor. Back of the motor cover and check front to back play. 




Nice work Rick!


Then check the linkage clearance








Lots of room on the rewound motor




Now run it through a few full cycles of the oscillation sweep by hand by turning the blade. Then back apart for the final lube and glue for the back nut on my oscillation linkage. Last step is re-peening the link that holds the new spur gear and ready for final assembly and power up.

Lube it up and let it run. 









Don’t forget the ball bearing

















Run in time :clap:

Off to the races now. Had some issue with the lower pinion gear in the neck. It had swelled and was tight in the base. Just some sand paper to clean up the ID.   It has been a push start thus far. May not have the starting torque I’m thinking now. At first I knew it was all the tight new mating surfaces but now I don’t know...







Oscillates smooth and runs quiet at .9 amps on high

Thanks for all the great work Lucas! I'd post a video of the fan oscillating for the first time in what must be decades, but I've no idea how to upload a video. It keeps saying invalid extension! Oh well...

Both Lucas and Rick were here for my little get-together lastmonth, great guys. Thanks for the pictures and write up!

P.S. I found the parts for the toilet bowl oscillator and will send them and the base this week.
