Helping a neighbor whose electric start stopped working. On disassembly, it looked like the brushes were well past their service life, and additionally cranking too long had heated the plastic ways the brushes slide in enough to deform one of them so that the brush was stuck.
I've found a source for the brushes, but I'm stumped as to how these starters were assembled. The brush holder assembly is screwed from the inside into the motor end cap; the whole assembly comes off the commutator as a unit.as a unit There are no outer brush holder screw caps.
I'm testing out using fine thread to pull back the brush springs and then cut and pull out the threads once the armature is slipped in----I don't have high hopes it will work, and I can't imagine how the factory assembly was done. Seems like a very poor design!
Any suggestions would be most welcome!!!!!

They had a very special setup to put those brushes in at the factory. Which will remain a X-File forever. Those starters are pretty much non serviceable. From a persons perspective. Try and find a shop that fixes starters and other electronic stuff in your hood. Because as it sits now, It nothing more than a paper weight. ALOHA!!!!!!!

Do the carbon brushes have a hole in their side? Is there a corresponding hole on the motor end-frame? My Honda Gold Wing had this type of arrangement in the brush rigging.

Push the brush into the brush box to compress the spring until the respective holes align and insert a toothpick etc. to gag the brush.

The "shop that fixes starters and other electronic stuff in {my} hood" is in my basement ;-)
As far as serviceable, SMD electronics fit that category, but starter motors? Hey, they sell the brushes, (unless I'm looking at a dead Web link) so.....
Somebody figured out how to put them together, d*mn it

FWIW, I have considered driving out the roll pin on the Bendix, since, while it would be "fiddly"
(that's the non-profanity laden description), I could probable ease the commutator past the brushes....

If there isn't a pinhole or something to hold the brushes back while the rotor is put in, then maybe this excerpt from the yamaha manual will give you some ideas as how to assemble it.

thanks....that might could have come in handy.....except it's a four brush setup, so not quite as easy as all that (and I expect I'd have to pull off the Bendix end because the armature/case would be in the way of a "tilt in".....

well, snarky, that wasn't the point....the point was I'd be happy to buy a new used one, but it probably would still need brushes....
I'm still kicking myself over losing the link for a new one....
