Replacing brushes? - Sullivan Dynatron.

[Terry Keeley]

Finally wore them out, called and you have to buy the whole motor. WTF?

Anyone found a replacement or have a junker they could pull some from?

 

[Danny King]

Reach out to mark bullard. He would probably know.

It’s been a lot of years but when I did one of mine I got them at ACE Hardware in their small parts boxes. The carbon part had to be sanded down to fit.
Thanks John

Well they're 1/4" square so hopefully they'll be easier to find than the ones for my Shop-vac...

Well they're 14" square so hopefully they'll be easier to find than the ones for my Shop-vac...

14 inches square, that must be one hell of a starter.

Jeeze Terry , you must use a cherry picker to put it on your starting table....lolol
Seriously.....Take your starter to your local auto starter & generator rebuild and repair shop.....
I would be willing to bet there is a standard set of brushes
sitting in their inventory to fit your starter.....They can also take larger brushes and sand them down to fit........

1/4" x 1/4" and how long do you need them?

Older Mercury trim motor pump brushes

 

[Terry Keeley]

Looks like they were about 1/2".

I found several 1/4" x 1/4" brushes on on the Helwig site but they all had a round stub where a spring sits.

These are flat since they use a seperate spring.

 

[Mark Bullard]

I will look to see if I have any laying around.

Terry, check out the Graphite Store on line. They have some that look exactly right.
Thanks John

Where?

[John Beardslee]

That’s the place, just search “ carbon brushes” and 30+ pages come up

 

[John Beardslee]

Do you think the 300B could be made to work? It’s 1/4” x 1/4” x 1/2”

 

[Terry Keeley]

Ya, looked at that one but I don't think so with the lead on the side...

 

[John Beardslee]

How about this one? You’d have to sand it to 1/4” x 1/4”

 

[John Beardslee]

Terry, if you are able to get brushes, take time to reface the commutator before reassembly.

 

[Terry Keeley]

Thanks, I'll turn the comm down while I'm at it.

Unfortunately those brushes won't work, I need the pickup wire on the end.
