just totally cleaned the inside of my d33 filter queen has all motor gaskets & secondary off & cleaned wiped carbon from motor brushed dust & blew it out
its all clean now
wondering why the brush on the right has a different appearance color is sort of like it has a bit or corrosion.
Its the same motor as the other I took apart same numebers on top but this unit serial # starts D5... power nozzle has a 78 sort of dat so think its a 78

these motors look same but the 33 motor was cleaner I've cleaned this one as much as I can. Brushes look similar to the other
hard to see but think even this motor looks better than the 86 rusty one
so I might just switch the metal top & pedal switch into this one & it will be whole. Can then slowly find the needed parts for the newer model as I clean that badly rusted motor so I figure that one had to have sucked up water
