Hello everyone!  I recently picked up a 24c1 on eBay on a whim.  Once it arrived, I found it needed all new rubber grommets and bushings, plus a cord, but the rest seemed ok.  I've torn everything apart and cleaned it up and started the reassembly process.

Yesterday I pressed the motor case halves back together and tried to oil it using the ports.  The front one is fine, but the rear refused to accept oil, appearing clogged.  I looked closer, and just below the outer rim, the tube is pressed together to form a very thin slit, which causes the oil to get stuck at the top and not drain through. 

My question is - what's going on with the port tube?  Did it originally sit above the motor case and flare out, similar to the front one, but someone squashed it down?  If that's the problem, I should be able to get it out and either re-form and press it back in or replace it with some other small tube.

Thanks for any help!

Brian

Here's another picture, showing a close-up of the port.  The shiny line in the middle is a reflection from oil in the thin gap.

I would not be too concerned with the tube mashed.  Chances are oil will get down to the bearing.
Front bearings always require more oil than back bearings.  I would fill the back tube and run the fan for an
hour (to warm it up) then let it cool down and look to see if the oil made it down.
Happy Fanning!

Hi Brian:

Make sure and post the fan when you're done. I've had the same problem on vornado's like yours. The front takes the oil fine but the rear doesn't take much. Like John McComas said run it for a while and it should take oil.

Will do! I went ahead and left it alone since it doesn't seem it's an unusual problem, or even a problem at all.

It's going back together, but I wish I could better center the motor in the fan body. I'm struggling to get the motor to stay a little higher. There's only a small amount of clearance between the body and fan blade at the bottom, but plenty elsewhere. Any tips?

Worst case you could take a fine flat screwdriver and tap it into they rear oil port. That would expand it some. Just be very careful. As to blade clearance I'm not sure what to say. Did you get a grommet kit from Crescent Industries?

Yes, I did, so all of the rubber bits have been replaced. Everything goes back together tightly and easily, but it's eccentric. I'm going to try to check the angle of the motor relative to the body.

By the way, I went an entirely different route with the foot rivets - drilled and tapped them from the inside so I could keep the originals. I'll post some pics when the fan's done.

As you’re installing the motor onto the struts, make sure the motor is not twisted at all and that the struts stick straight out from the motor axis, rather than an angle. I hope that makes sense. 

If the struts are not straight, it can create the problem you describe.

Lane,

That does make sense, I had a similar thought last night. While the motor wasn't twisted, the motor was angled down in the front quite a bit. I bent the top strut and threw in a few washers where the strut connects to the motor mounting collar. It's much better now!

I got the new power wire connected to the motor leads and the end cap is on. Should be done this week - thanks to all for your help!

Put several drops of lighter fluid in that back bearing.
If you have hardened oil the lighter  fluid will soften it .
You may have to do this several times.
If you have the motor opened up its a good time to clean those  felt wick's .
singer sewing machine oil or 3 n 1 blue label for fractional hp motors zoom spout .
no penetrating oil.
