For my two cents worth, I just plan to treat the dual row bearing as a replacement item when I do the clutch. Whenever that occurs. Since I don't have the previously history I can't say when my clutch is expected to fail. Same thing for the ISMB. Who knows when it will fail much less if it will fail. If it happens, it happens. If it lasts until my clutch needs work I'll replace it then regardless of its condition. Until then, I just step on the pedal and don't worry about it and enjoy the ride.
