Someone gave me a working Manning Bowman Model 085002 that runs but is in rough shape overall. I wanted to completely disassemble it and clean all of the rust off of it and I have hit a roadblock as it seems part of the electric motor is stuck in the housing. It looks as if the housing is crimped onto the motor. Is there a general technique or procedure used to separate the motor and housing?

Sorry, I don't have a good answer for you! Looks like your motor was made after we moved into the era of cheap, not meant to be repaired manufacturing. Someone probably will chime in with a suggestion ........ now, if you remove stator without damage, how are you going to secure in case on reassembly???????? Can't bend those steel tabs back and forth many times. Not familiar with that motor.......is it worth the effort??????

Show a pic from the back. You will likely need to "walk" the stator out of the housing . I use a screwdriver to do that but a pic will help to know if you have the fan I'm thinking of.

The crimped areas stop the stator from going in too far, they are not holding it if it is like the one I worked on. Lane is right as it is pressed in.

Thanks. That is the confirmation I was looking for. I was able to try a bit harder and get it out. There is plenty of corrosion and rust that was keeping it in place.

Be sure to remove the disintegrating tape on the coils and retape them with friction tape. Probably wouldn't hurt to varnish them also.

Also, there seems to be some sort of bronze type bushing in a bracket, that supports the back end shaft of the rotor. I'm not sure if that is the only purpose it served, but it is quite a bit heavier than the bushing in the front fan housing, and there seems to be some small duct that runs to the side. Any ideas on what this was for?

Yes that is the bearing carrier. The tube is the oil tube, but while you have it apart, soak the felt pad that it leads to with Zoom spout or 3 in 1 SMALL MOTOR oil. Also there will be a similar pad on the other end -  soak it also.  When you assemble it, make sure the tube points UP.

Be sure to clean all of the rotor and bearing contact surfaces with mineral spirits then dry and oil them while you have it apart. Don't forget the positions of the fiber washers on either end of the rotor

So there is certainly something inside the bearing carrier. I can soak it is something but if it starts to disintegrate and come out, does that mean I'd need to drill out the rivets and rebuild it? The other side of the rotor shaft goes into a similar bearing assembly, but I don't see any felt or material inside.

Sorry for all of the questions. I've never done anything like this before. When you say clean the rotor and contact surfaces, you are talking about the shaft where it rest on the bearing? There are 6 different washers that came out of the assembly, but some of them don't seem to be in good shape. I made a drawing of where the washers were as best as I can remember, but I'm not 100% sure. Is there a way to figure out where they would need to go?

Yes, clean both ends of the rotor shaft with lacquer thinner or mineral spririts. Do the same to the bearings using a qtip and solvent. 

Then oil them before reassembly. Behind that riveted plate is the felt washer.  I've never had one disintegrate. My suggestion is to get a can of CRC lectraclean at Home Depot. Spray the felt washer until the runoff is clean. Let it dry overnight then soak it with oil, about 10 or more drops will saturate it. Before you reassemble, make sure you haven't over oiled it by standing the motor bell on end and see if it runs down the inside of the housing. If not, you're ok, if it does, clean it up and then reassemble. 

Both ends should have the felt. Post a pic of the one "missing" the felt.

I might add to what Lane said is that the Front Bearing as illustrated in the photo below does have an oil port for oiling the bearing, the rear bearing though on the other hand I don't think was meant to be oiled as it doesn't have an oil port on it and it also doesn't look like it has a oil wick in it or that it ever had one in it to begin with, remember this was a dimestore model fan it wasn't meant to be a super high quality fan to begin with so it would only make sense that it only has one bearing that was meant to be oiled. 
Hope this helps.




Note the area in the red circle is the aforementioned oil port for the front bearing assembly.

The bearing in the main housing is a through bearing if I'm seeing it correctly. That means you can add a drop of oil on occasion directly to the bearing.
