Copper showing is not good. I'd replace them.

any copper showing on any surfaces other than the seam means they should be replaced. pay close attention to the e-shaft bearing surfaces for damage and to be sure they are within spec as well, you may have to use a different e-shaft or use a thicker bearing and have the shaft milled.

ok i have a new eshaft coming anyways....mabee i can pick up some used whole assemblys witth good bearings cuz i have no press or anythin

I good machine shop could press the old ones out and new ones in for very little money and very little time. You might look around your town, most places have at least one machine shop.

Have you seen Scalliwag's nifty neato bearing tools? Press not necessary. http://www.scalliwag.com/

if the copper showing is less then 30% of total area reuse the bearing, if otherwise the surface is in good condition and the copper showing is not from bearing feailure.

I would replace them.
If the copper spots were small, it would be different.
This kinda wear...to me...implies some sorta misalignment or out-of-spec part.

Stat gear bearings are cheap - $11 / each? - it's small insurance for a rebuild.
