The blocks with pins on them that you were talking about are called inserts. They fit on the back side of the concave. There is an upper and lower row. A lot of the combines I look at, the top row is missing. They catch the most abuse. They work back and forth and ware the insert out or break the pin. Especially in tough conditions like running at night. If these inserts are not in for beans you have a lot more trash goin over your sivs and a lot of beans that are unshelled this will carry over because a lot of trash on the siv area. That would be the first thing i check.
