Okay let me start out and say that I'm an idiot and I did what you are not supposed to do and that was to take apart my sti shifters (shim 600). They weren't shifting down because the factory grease turned to sap. I was able to reassemble the front shifter after cleaning but the right (rear) is a puzzle. Does shimano have the schematic diagrams for this? I know they are assembled by a robot, but I think I can get it if I can figure out the orientation of a couple pieces. I've seem people say they've done it but I need a picture or something. thanks
