Ok, I am young (17), and I want to rush through everything, and that can be costly, and I've learned my lesson today. I read the thread on how to adjust the ALDA on a OM617, and I just skimmed through it (BIG MISTAKE) and proceeded to try to loosen the screw without first loosening the locknut. The head of the screw split in two. I went back and reread the directions, realizing my mistake, so I loosened the locknut all the way, and I tried to loosen the screw a little bit with my pliers using the half of the screw head that was already there. I'm not sure if it moved, but it looks like it did a little bit. I found the other half of the screw on the garage floor, and if possible, I'll attempt a "screw repair" using some sort of "super glue". If that does not work, I may have to go to the MB yard and get a screw. But, I've learned my lesson, and that is to READ, and RE-READ. Oh well,
