I'm not sure I have all the parts, or the correct parts, for this fan: A Hunter Century C16, pre-1950.

After disassembly I noticed that I may be missing a small hex nut. As seen on the On/Off control, there apparently should be some sort of hex nut or bolt head to fit inside there. The 1/8" 32 tpi screw is all that it had. Would anyone know what I should have, and what the correct dimensions should be? Are the threads reversed?

A little more info: The knob and screw do not actuate the oscillation gears. That is either because the knob just spins around the screw, or because the last 2-3 threads are worn down too much to turn the gear. I am guessing that a hex head type of screw, inserted into the knob, and the pair threaded onto the gear may be needed???

I didn't attach a photo of the oscillation gear connection point since it is masked over for painting at the present. I was hoping to have this puzzle solved before the final clear coat step.

Any ideas would be appreciated.
Thanks, Pat

I have a later version of your fan, I'll take a look at how the oscillator knob is done on my fan and get back to you.

I took a look at mine and it appears that mine just has a screw in it holding the oscillator engagement knob into place like what yours did. there may have not been a nut down there to begin with.

Thank you sir!

Best I can tell the threads are reverse, yours?

That may explain my worn threads, and lack of proper engagement with my oscillator gear???

I believe that's the way mine is as well, reverse threaded. It could be that the screw is not tightened down tight enough, I know that's been the case with some of my fans.

Hey Pat,
If you have a tap and die set you may be able to chase the threads on that screw and clean them up.
How much extra length does it have ? If it has a few threads to spare in length you can cut the stripped end off and de-burr it, then run it into the oscillator drive shaft and it should tighten up for you.

Thank for the idea Joel. I actually have a thread chaser tool I bought in an antique store.
It goes from 1/16th inch to 1/4 inch in 1/32nd steps, but there is no tpi specs listed :-(

I thought I would give it a try just in case it spins around as smoothly as it should. It is a real nifty tool!

Thanks,
Pat
