schematics of Helios M.C 2.8/28mm

HI all! Currently im trying to clean and refurbish an helios MC 2.8/28mm objectif. The spring mechanism for the diaphragm its not working , someone fiddle with it and made it worst so now i dont have any reference point. Thats why im here asking if someone already cleaned this lenses or now of a site where i can get info in how to do it. Thanks.

Managed to fix the spring mechanism..after disassembling the optics barrel i managed to get to the diaphragm blades , cleaned them one by one and put them back in place (no shaky hands here ) after that they opened and closed effortlessly which was stopping the spring to pull it back to its initial position . Now im trying ti put it all together , but its revealing to be a bit tricky....
