Fantastic Fan Motor Brushes / Bearings ?
I have no way of sourcing information about the vent fan motors. Can I safely asssssssume the vent fans use the same motor as the box Endless Breeze fan? Do these critters use ball bearings? or do ...

I replaced the brushes in my FF last year because they had worn down so much that the fan became intermittent.
I drilled out the rivets to open the case.
For replacement brushes, I used some Harbor Freight replacement brushes that I had lying around. They were a little too wide, so I sanded them down to fit. The hardest part by far was to hold the brushes retracted while you close the two halves of the motor. The commutator doesn't end up under the brushes until the motor halves are almost touching. I used some bent paper clips to hold the brushes retracted, with part of the clip hanging outside the motor case. Then I pulled them out to release the brushes as the motor halves closed. The permanent magnet is very strong, so as you get them close they snap together.
