Can anybody familiar with Vornado bushings explain how the oil get from all that felt through the brass bushing to actually lubricate the shaft. The brass material does not look porous and not sure if it is supposed to magically just seep "around" the ends of the brass and just happen to get to the shaft-bushing space. I cleaned and re-lubed mine and it still got hot. Then today it is seized up on the rear. No wear that I can feel horizontally or vertically. Cleaned felt very well(felt looked dirty but great structural condx), then I used synthetic oil for fans so not sure how to even fix the GD thing. Bought it from a shop that claimed it was re-wound/re-wired and "better-than-new" ha. When I popped the motor open it looked like it has never been opened since 1955, much less rebuilt/re-wound. 
The cosmetics are perfect. Re-painted base and motor with nice chrome job on the cowl. It's all style and no mechanical substance.I'm thinking I will take it back and try to recoup my losses because I don't know what else to do after such a thorough cleaning and recon in the motor and still can't get lube on the shaft for some reason. BTW, coils look fine to me and kill a watt reads 2.3 Amps.

DAVE THE BRASS ACTUALLY IS POROUS, AND THESE BUSHINGS CAN TAKE AWHILE AFTER BEING DRY TO START UP EASILY AGAIN AND RUN LIKE NEW.... AND I MEAN QUITE A BIT OF TIME. ONCE WARM THEY RUN GOOD AND THEN AS THEY COOL AFTER SHUTDOWN CAN GUM UP AGAIN. i ADD MARVEL MYSTERY OILL TO GET THEM FREE SO THE  OIL CAN WORK ITS WAY IN, AND STILL A SLOW PROCESS. THE ISSUE OF REWINDING I CANT COMMENT ON, I WONDER IF THEY MEANT "REWIRED" NOT RE WOUND. IT IS A GOOD FAN AND ALTHOUGH NOISY THEY MOVE LOTS OF AIR.......

Tom-
Thank you for the info. I didn't realize the brass was porous. I did soak them in mineral spirits but sounds like they need to be freed up and given more run time with MMO added. I read that the MMO is compatible with synthetic oil and I have liquid bearings fully synthetic.
I went back and looked at the tag and they claimed rewired,rewound,repainted,chromed, and "as good or better than new". As beautiful as they made the paint and added chrome(not cheap to do), I figured they probably did restore the motor guts but that was the amazing part. All that extreme work of cosmetic excellence and absolutely NO mechanical/functional attention- at all. Crazy. I may end up keeping it and continue to bring it up to electro-mechanical standards because it deserves. I spent a lot of time last weekend cleaning the inside of the motor and even removed the felt wick housing rivets and replaced with screws for future maintenance to get the felt completely out for cleaning. That's why I was shocked that it had clean felt, fresh oil and then ran hot and seized up. It's good to have you guys with experience to help. Sorry for long-winded rant but I appreciate your help!!

Did get some MMO soaked into the bushing along with plenty of fan oil and am now firing it up to let it warm up and see how the uptake is. It did seem like I would coat the bushing with the actual oil and it would take it up but I might have been imagining it. I am thinking the MMO with evaporate out with the frictional heat and maybe the load of fan oil will make its way through. Even though I thought I had enough oil in after the cleaning, I am now thinking it wasn't quite saturated enough. It seemed a little dry when I pulled it apart to free it up. Fingers crossed.
