Brush Sleeve brass ring keepers

[Marc Sova]

76046….Reassembly of brush sleeves  does this seem like a reasonable plan:

Am I correct in thinking that I should de-solder the wires from the brass ring keepers. And then screw them back on the brushes to get decently snug, and then re-solder the wires into the brass keepers?  (See video). Obviously that’s not how I removed them. I grabbed the rings with pliers from above and then stuck at 3/8” socket extension into the brush holder sleeve and turned it. Not the best way.

Oh my. Might want to post a clear picture.

Worst case resolder. First I would leave soldered. Use soapy water as lubricant on brush sleeve and turn it with ring on inside so that you are screwing sleeve into ring. If feel cant get it tight enough use 3/8” stock inside the square for brushes as a way to tighten using wrench on 3/8” stock

Great video btw

 

If you decide to resolder I would cut the wire and resolder wire vs at the threaded ring. Odds are the wire slips into a small hole on ring. Even if not so soldering a wire to ring from other opening more difficult than two wires cut back about 1.5” from ring

well…. The reason I wanna remove the wire is the square inside of that sleeve has to be oriented pretty perfectly straight up and down. I feel like I could do a better job of that if I was just holding it tight and screwing the ring onto it, rather than turning it into the brass ring. But I suppose it’s not going to be that tight and I’ll be able to adjust it a bit. .
 

Oh….I hadn’t thought about soldering wire to wire….so snip the wire, expose and clean the strands (and maybe even tin them?), then screw on to brush sleeve, then solder and heat shrink at the wire. I might have to add a tiny bit of new wire I suppose. 
   Yeah I removed them with a 3/8” socket stuck in from the outside and held the ring with pliers. Worked great on the first side. Then I didn’t realize that I forgot to loosen the set screw so the second side was a real pain. Knowing what I know now I would’ve made a 38 inch tool out of like oak or something. So as to not damage the threads.

Gotcha. Did not think of squaring up brush. Id cut and solder wire

Ahhh, my bad. I missed the fact that it was a video, sorry. On my device the play button kinda blends with the background pic. Yes it works.

Well I got it back together. At least the motor. Thanks for all the help on these sleeves. My first dc fan. 
   I ended up doing a sort of hybrid version of what Chris suggested. The wires were kind of iffy where they were attached to the brass rings. A couple strands broke etc. So…I ended up cutting them and then soldering a nee bit of wire to the ring out on the bench Swjere I could get at it better. I then screwed it in the sleeve and determined the best orientation to meet up with the existing old wire. I then cut that wire short, removed the shielding, and soldered to that. And then heat shrinked it. Worked out pretty well. Was indeed easier to solder to that wire than it would’ve been  dorectky to the brass inside the fan cause it was kind of a pain doing it in the bench. And there is NOT a lot of room in the nose if this fan to work. 
   Did a quickie en ch test with a rectifier and she works!!!!  Not to get all that wicking good and saturated with oil. But I’ll fix the typos that I’m sure are present later. Got get up daily and fly back to ca tomorrow.
