Service a starter motor: worn brushes

As brushes are unavailable, your options are: 1) crimping, 2) soldering or 3) fit in an extra brush piece with no wire. Detail work, but why spend hundreds when $2 can make it work?

[@wadepatton2433]

Many years ago I took starter brushes, filed them down to fit and used them to fix the window motor of my pickup. Never failed again. I had the truck 9 years and pushed it over 300k. I'm working on a starter now, and ran across your vid. Diving into my starter for the 4th time now. I've lost contact to the control terminal/ pull-in coil. But first- lunch!

[@theoverengineer]

Right on

[@frankiecastanos6730]

Thank you so much for the info. You just saved me $500. And the trouble of trying to find replacement parts witch im finding out is not so easy for my zr7. Thank look forward to more video. Sigh Frankie. C..

[@theoverengineer]

Glad I could help

[@paulbuschman8318]

Any tips on keeping the brushes recessed when putting back together and getting the brushes over the commutator?

[@patmatte]

wouldn't putting the add-on piece behind the brush between the spring and the brush be better? Also great video I'm about to try this with my snowblower starter.

[@theoverengineer]

That works, too

[@kevin.afton_]

And your add-on piece could be anything if you put it behind it, even just a piece of wood too.

[@gerardogle1732]

Wood does not conduct electricty ​@@kevin.afton_

[@ninoechavez1402]

When i serviced my motor, was there any chnce i might have assembled the brushes wrongly? Motor seems to rotate the opposite way now and my starter clutch just spins freely and won’t crank when i press the electric start.

[@theoverengineer]

Oh yes. Very wrongly assembled. Switch the wires around.

[@ninoechavez1402]

Does the motor normally rotate clockwise or counter clockwise?

5:30 Goodntight "that's what she said ya!" Thanks Chief. If you are in dire need of brushes go to harbour freight or Walmart and get 1 or 2 angle grinders and remove the brushes!

[@jigo53]

im replacing the brushes on my cb500 only after 20,000 miles.. is that normal?

[@theoverengineer]

Not quite normal at all, but if they're worn down, not much can be done besides replacement

[@michaelthomas788]

I've worked on motorcycles and cars for a long time I recently tried fixing the starter like that didn't work too well I think it turn the engine 5 times before it burned the brushes

[@theoverengineer]

Overcurrent is burning the brushes off. Somewhere these is a stuck bearing or something is misaligned, causing extra resistance ...

[@michaelthomas788]

theoverengineer if you've ever rebuilt starter you know that most starters don't have bearings there bushings

[@theoverengineer]

Somewhere - I said Find the source of friction

[@michaelosmon]

@@michaelthomas788 my waverunner starter has bearings in it

What are you trying to do in the video ?

[@theoverengineer]

solution options for limited markets

[@s99614]

Where can I get new brushes for $2??

[@theoverengineer]

From an alternator / starter place, might look like this at 3:45 kzbin.info/www/bejne/eH3Qi3SHmrKAb9E

[@michaelosmon]

Ace hardware

[@ideasdonato]

Where you bought this carbon???

[@theoverengineer]

Just found some at a used starter repair shop. I asked for it nicely, it was free.

[@alyaawaliyah]

what is wrong if the starter spinning in wrong way after i change the bush and bush body starter?

[@juanherrero911]

For my starter motor, fitting the middle section of the starter motor, which has the magnets, the wrong way round caused it to spin the wrong way.

[@whitestar3531]

Add on ? Super glue ?

[@theoverengineer]

A big enough chunk (nothing too thin) will stay in the sleeve by friction, no glue or anything that impedes electrical conduction is needed.

[@whitestar3531]

Thanks for replying, ok that's wonderful info, thanks 😊

[@UPTHETOWN]

So much wrongness 1. Not ground brush, positive 2. Not soldered, spot welded 3. Not friction fit, spot welded
