These brushes are stamped E27 - they measure .25"X.437" - the longest ones we have taken out measure about .9". Each servo takes 8

Try Helwig Carbon, they are one of the major brush suppliers, I get Getty's, Fanuc & Mitsubishi brushes from them.
That motor appears to be the Getty's style.
Make sure you take the brush holders frame out and clean thoroughly, they leave heck of a lot of carbon over the years.

If they do not have the size under Inland look under different makes for the same size.

thanks again

the wider ones might be trimmed to fit.. Have to look. It looks like I can get the exact size from graphite store..

Another question. Do you think there would be a problem pulling the rotor out of these? (they are old - like early 80's or older.) One for sure needs the commutators trued.

thanks

I have pulled the rotor on a few, some say place a metal keeper in place of the rotor, but I never have, the thing you have to watch is when you pull the armature, it is going to attract strongly to the stator, these magnets chip or come loose with shock, so care has to be taken.
