What I usually do is remove all the rasp bars but two straight across from each other. When I reinstall the concave I hook a chain to the concave and one rasp bar and pull or pry down on the one in front to help "roll" the concave back into place. The easiest way is when the shaft running through the cylinder is bent or the right hand spider that the rasp bars are bolter to is broke. I remove the shaft then use a cherry picker to lift it in and out.
Mentioning the spider on the right side check the weld around the hub. On the 9600 and 9610 combines those like to break away from the hub.
