Won;t page Dr Lux Know he has his own patient on the table
LOL
Took out my first motor brush
Got a cheapy filter queen 2 hours cleaned it up head to toe
works hi & lo but on hi I could see into the motor is was fluming bad & arching green fireworks clicking
didn't think it was good
So opened the motor again to look at that area couldn't see naything on the brush
only thing I see is that brish is a lil lower on the armature than the other side
took the brush out its long guess about 1 1/2 inches
So I heard over 1 is ok
cleabed the pink holder cleaned under the top motor couldn't see anything really
put the carbon back in & on the motor held its fine but screwed down the top of the carbon is below the top of the armature where as the oher side is level with top
Thought maybe it was upside down but I couldn;t get the carbon out' its held so left it as it was
tried a few times to screw it down as best I could it still wants to sit down
tested it outside on lo ok
tested it in hi didn't see to plume like it was but it was bright out
Anyway did all I could do so I put it back together
its seems to just be a normal sparking brish now on hi no worse than any of the others
So what was it?
Maybe it was a new brush & not set well?
Anyway it seems better
Good thing I thought I had a 2nd lo only vac
LOL
Still this one was worth the parts but being a darn 82 its more plastic inside but on the positive side the motor is 8.3 amp without pn & 9.5 with
without ots almost 2 amps more than a 78 model Has the new style motor
Still I needed the parts & this one had the retract cord dolly & it works too...
I figure I could put any motor in it & still keep that nice dolly feature
It will evenutally get good old metal insides from one of my old half workers
LOL
Here's the brush orientation pick taken when I finished the right side is the one I had out

I changed the distributor cap on my benz I do know that arching can create carbon deposits on electrical parts more carbon more arching as the carbon seems to conduct electricity least you lose a good spark to the engine
anyway would cleaning the brush holder be all it needed? or was it blackened becuase it was arching?
found this guess you have to replace the entire colored unit when you do My brushes are at least 1 in so well one is so its likely the other is.
Good thing I looked though it was obvious from the outside as when the motor was on high after abiut 30 sec you could hear something clicking & when looking in top there was a bright green plume lit up the entire inside
Could be why it got the boot...
LOL
Still brushes look to be hardly used or else they were replaced as it is a 82 motor & casing also is stamped 82
Motor looks ok cept I notice on top of armature there are the copper top but in a few locations it appears to either be missing or else covered in the cement they seem to be set into that makes the top of the armature...
pic tries to show this
Also found this says lil spark at brush is ok but not so it wraps around...anyway what I saw was not good hope it stays away
Also says something about top & field angle says it controls speed of motor & to reinstall exact way
I didn't open this motor up but I probably will at one time as I did have success with the 2 power nozzle motors I did thelast one had the entire thing apart & got it back together
