Eureka
I have the hunter green eureka esp model 2091. I still have to get a couple parts for it. After using the wrong bearing. well right size bearing from a skateboard but the inner ring stuck out to far and pushed the armature up a little bit so it raised the commutator and the whole upper motor assembley and the carbon brushes would not seat right at all and or properly so I took the motor apart and it resides in a nice neat little pile in my basement at this moment til I can get the parts needed. if anybody wants pics of it despite the state it is in right now I will be more than glad to take some pics.
