I just bought a used eaton for a swap onto a marauder. Was told it had about 40k. Is it normal for some of the black coating(Teflon?) to be missing? I'd say about 10 percent is gone mainly around the edges. Also it spins freely with no funny noises but there is a little play when I move the pulley back and forth and when the rotors actually move. No play between the rotors themselves. Again normal? Thanks
