I’m confused, quartering a wheel has nothing to do with rods being adjusted, ……are you talking about the eccentrics? ……if the little tabs on the end of the eccentric cranks ( the part that goes into the wheel ) are broke off, it can make keeping the eccentrics in time a real chore. Best to post up pictures of your locomotive, and use a pencil or something to point at what you are adjusting ……
