I have a Sears three speed, reversable 4 blade all metal window fan. Any info would be greatly appreciated. How do I oil it(do I oil it?) What model is it? Is an owner's manual available anywhere? How do I (or can I) refurbish it?

I'm not familiar with that particular fan, but if I look at your photo, I think I see an oil port (looks like a hole) near the diagonal bracket on the motor. It should be at the 12 o clock position on the motor. There should be another similar hole on front of the motor as well. Sometimes you have to remove the grille to get to the front one. 
Use the proper oil- I'd buy Zoom Spout oil on Amazon, or your local hardware store. Do not use the wrong oil. About 5-10 drops should be good depending if you think it's been oiled recently (likely not). 

The most important thing about restoring it is to make sure the wiring insulation is safe, even in areas that you can't easily see it. Ideally, it's usually best to split the motor apart, remove the rotor, and clean the clearings with solvent. There should be a felt donut next to the bearings that you can then access and soak with oil. You can also then reoil the bearings with fresh oil. 

I hope that helps with your questions.

Lane, Thanx I found the port. Now how do I split the motor? Is this a diy thing or do I have to go to an electric specialist?

Hey Ken,

It looks like you've got a GE reversible motor in that fan.  No expertise needed for this task.  As soon as you free the blade and mountings, its a matter of removing the threaded studs (usually 4).  From there, you should be able to see on the edge of the motor a shallow lip or tabs that you can gently tap to "crack" the motor open with using a hammer and flat head screwdriver.  If I'm not mistaken, both end pieces remove, with the center of the motor + winding coils being on their own.  If you need to remove wires, be sure to label them or snap a picture or two on your phone.  When you get the motor back together, don't forget to re-align your bearings if the motor seems stiff.  I typically do this by LIGHTLY knocking on the motor shaft UP-DOWN-LEFT-RIGHT with the handle of the screwdriver to prevent bearing damage.


It looks like you've got a really well built fan there!  Congrats and I hope I could help.


Regards,


Mr. T

Mr.T, thankyou for the info. I'll be starting this weekend. Once the motor is out,it'll get cleaned and maybe a paint update. Anyone know where I might find the atomic logo?

Well, I've split the fan as suggested. Oiled the bearings and checked the wiring. No cracks. When I turn the fan on it doesn't start and I hear a faint hum. Took the box that covers the the controls off. What is this silver thing? Could it be the problem? How do I post pictures? Did last year and forgot:?
