[TowerTalk] Brush replacement on a small prop pitch motor

[Alton McConnell]

I am having a problem with a brush in a small prop pitch electric motor.  I disassembled the electric motor and replaced the beaings.  When I was putting the motor back together, I noticed that one of the brushes popped out of its holder when I removed the armature.  The other five brushes stayed in their holders.  They are spring loaded and seem to function properly.  I cannot get the one that popped out to stay in its holder.  Any advice?  Does anyone have a photo of a brush?  What keeps the brush in its holder?
 
I noticed that the bottom of the brush holders are accessable from the top of the motor housing near the pins for electrical connections.  I would think that the holders caps would be removable for easy brush replacement but my holder "caps" do not want to budge. Should the caps come off?   I can provide photos if anyone is interested.
 
Thanks!
