I have a pair of shimano m520 pedals which were damaged in an accident. The springs rotated past the tension bolt and now the back section, usually under tension, now hangs free. How can I re-assemble the pedal and get the springs back under the tension screw? It seems very difficult since the springs need to be held under tension to get the plate back on top of the springs. Is this possible with home tools?
Here's a link to an assembly diagram: http://www.shimano.com/media/techdocs/content/cycle/EV/bikecomponents/PD/EV-PD-M520-2235_v1_m56577569830608614.pdf
