It's been a while since I had one apart but it's not too complicated. The center hub has a flat side which on the outside with the clutch installed, sit that side on the table so you have the protruding inside of the hub facing up, the spring washer goes over the center and sits on the hub. Then you have the three shoes, with one pin each, the pin , the groove in the shoe for the spring faces up (toward the inside of the clutch). With the three shoes in place you have three half circle flat springs with a square tab on one side and a round tab on the other. Put one inside the spring groove with the square tab through the gap between the shoes, then install the other two, with the long end overlapping the tab end of the previous flat spring. Then set your clutch spring so the area where the ends connect ends up in the center of the shoe and tuck one part of the screw under the round tab and put a clamp there. Work your way around pushing the spring into the groove and put another clamp where you run out of slack. Now carefully use a flat screw driver to work the spring into the rest of the groove and around that last round tab.
