Nice! I remember seeing one of those in a fishing gear store when we went on a vacation to the beach, except it was white. Hope you can fix the noise! White is probably the more common finish. I've ne seen these fans in public, but that's no surprise, there's few good fans around here. The noise will get fixed, it's just a question of when and how (oil or entirely new bearings)

Nice! Enjoy it, they're quite nice fans! Thanks! I will enjoy it once I get the bearing situation taken care of. This thing is insanely powerful!

Saw your video, it looks like a nice fan. I hope you are successful in resolving the bearing noise It is in great condition, some of the parts were still in the original plastic wrapping. The bearing noise will get fixed, whether it be through oiling or replacing the bearings completely.

Nice fan, that's too bad about the noise, I hope you can get it worked out without too much of a hassle. That was a bit of a disappointment, but of all the things that could go wrong at least this can be corrected somehow.

Almost sounds like the noise is coming from the bottom bearing too.. Did you regrease the bearings? I just saw you put oil in.. If you don't regrease the bearing it will still make that noise.. Lithium non detergent grease.. I must have opened, cleaned, regreased one of my sears/emerson spinners about 20 times before it got quiet, after going through 2 cans of contact cleaner that was about $14 in total and still wasn't 100% quiet.. The air compressor technique sounds like a good idea.. I haven't tried that.. Bearing pullers are pretty expensive, $30-$40 range and higher.. They make two kinds.. One that grabs from the inside if bearing is stuck to plate instead of shaft, and has a shaft with a weight that slides up and down, and the more standard type that has 2/3 claws that grabs on to the bearing and uses the shaft to pull as you screw... Even though they are expensive, they are both good to have and will pay for their selves the more you collect and replace bearings...
When I pull bearings off the shaft of a ceiling fan.. I wrap the wires with some kind of cloth material and put a small piece of wood or metal over the shaft and wires, so the pressure of pulling the bearings won't cause the wires to get cut up by the shaft or puller it's self..

I wrap the wires with some kind of cloth material and put a small piece of wood or metal over the shaft and wires, so the pressure of pulling the bearings won't cause the wires to get cut up by the shaft or puller it's self.. I originally thought it was only the bottom bearing that was bad, but then I opened it up and and spun the motor without the top bearing attached, and it wasn't noisy at all. I'm convinced that its only the top bearing that is causing the noise problems. The air compressor got all the grease and WD-40 out in seconds, very effective. Would definitely recommend it, just make sure you wrap plenty of towels around the bearing (top and bottom) otherwise the junk in the bearing will go all over the place. From my years working in an auto shop, I am familiar with and have used bearing pullers before, just don't have any of my own. I would have a problem spending 14 dollars on cleaners and sprays to fix the bearing, but I don't mind spending a large amount of money on tools. As you said, they'll be useful for future fan projects, plus I'm a do-it-yourself person and am always working something around my house. Interesting idea on the wires, though I would think you would loose a lot of force having the wood and cloth between the puller and the shaft. In trying to figure out how I would do that, I figured I'd just put the puller on the edge of the shaft, but my concern would be if you strike it and it slips, it would probably sheer off the wires.

You'll still have the force, cushion on the wires protect the shaft from cutting into the wires, and a block of wood or metal protects the threaded shaft of the puller from grinding into the wires and gives it a better grip.. That's the technique I came up with when I first started to pull bearings..

If you're going to use only oil, you need a lot more oil than I saw you put in it.
Personally I never remove all the old grease, you intend for the wd40 and fresh oil to loosen up the oil grease. But if it was the only way to get all the black stuff out, you may have needed to. In which case you need to repack it with fresh grease.
I'm not convinced the bottom bearing isnt part of the problem, either.

I'm not convinced the bottom bearing isnt part of the problem, either. I was performing the oil/blow/grease/etc. process for over an hour, I only took a video for a short period of time because I figured it would make for a boring video. I put enough oil to fill it to overflowing and let it leak out several times before putting it back up. I don't have the right kind of grease at the time so I didn't put any in, but I'm also not using the fan regularly. I turned it on just to test it. The bottom bearing may not be the best either, I'm not 100% sure, all I know is the bottom bearing is smooth, its only the top bearing that feels like there's grit in it. I'm going to get a bearing puller soon, I'm asking around to see if anyone I know has one, and if not I'll just buy one. This stinkin' bearing has wasted so much of my time, I'd rather do something that I know is going to work at this point even if I have to wait a while. BTW Thanks for your reply to Sean's dumb post on DT about replacing the bearings lol

Letting it leak out is part of your problem. It needs to stay in.
Before you try anything else, try packing it with grease.
This is good because you're learning. Too bad you had to learn on a NIB fan, but this is something you'll need to know for lots of fans.
After having done dozens, I can get 90% of motors near silent and perfectly smooth with just oil and WD40. That said, if I need to open the motor for any other reason, I always replace the bearings. New bearings will always run better than old bearings.
I dont have a bearing puller, and so far I've been able to remove the bearings in all but one fan without it. I actually bought a bearing puller, but it didnt work with all types of motors, so I returned it.
