Has anyone measured the carbon head of a new brush, presumably during replacement? The cross section measures 7mm x 17mm and the worn length of those in my restored motor is about 14mm. I believe the original length to have been somewhere in the 17~19mm ballpark. I expected I'd need to turn down the commutator to true it up however it has zero detectable wear. Even the brushes don't really need to be replaced but at $1.50 a pair that as well is an inexpensive clock to reset.

Sweet deal on your brushes, btw. I haven't seen new OEM's (4540007) for less than $5 each. -
