Need Brushes for 1921 Starter/Generator


Recommended Posts

Rich,

These North East brushes are getting hard to find. DodgeKCL has a good idea

to check local electric shops but one caviat. Make sure to get ORIGINAL N-28 copper/carbon bruches. Do NOT use all carbon brushes as they will work only for a short time before completely fouling up the commutrator and quit working.

DodgeKCL,

There is quite a difference in brushes for an alternator or generator vs. brushes for a starter. The later must handle much higher current. The '21 NE combo is both a generator AND starter in one unit so the brushes must be able to handle both modes of operation. At least the two 'main' brushes. The third brush is, in fact, a solid carbon and is thinner than the others.

Roger,

Thanks for the info. Just to make certain that I understand. The 2 main brushes should be N28 Copper/Carbon brushes and the third brush should be solid carbon. You believe that my local rebuilder will understand N28 copper/carbon?

What about size? Do you know where I might find the length of the original "new" brushes?

Thanks for you input.

Rich
