bearing questions
 

when a bearing is turning cooper color is thaqt bad and also what exactly haoppens with a spun bearing is that the rotor bearing

yes when most of the bearing is copper its bad and when it is no longer smooth then its bad.

and bearings spinning is where the actualy bearing spins inside of its pressed in location, i havent heard of it happening on rotaries that much more on old high mile piston engines.

When you start seeing copper, that particular area is worn down alot. the spun bearing can damage its seat and or the eccentric shaft its connected to. Spun bearings are never a good thing to hear about

well I was cleanign stuff and I used vinagar to clean stuff anda s soon as I washed my stuff off it was copper color

now was it ALL copper or just a small spot? i think these bearings may be questionable, but if its ALL copper then its bad but if its a small spot; like around the seam then it should be OK.
