Best i remember from changeing concaves on 815 yrs back was undo bolts behind concave on adjustmant eyeblots, wire to cylinder an rotate in reverse, and unroll them out to you, Reinstalling wire back to cylinder rotate cylinder to pull them in, , then crawl in on sieves an reinstall side bolts an have fun reinstalling all the front bolts, I still remember it was quite a job! goodluck
