On the left side, we will be removing this lever.

It is held on its shaft with a retaining clip and a washer. The clip is actually just what appears to be one loop of a thick spring. Find the gap in the wire, then use the dental pick and a very small screwdriver to pry apart the gap enough so that you can remove it with the needlenose pliers.

Remove the washer (5/16" outer diameter).

Also unhook the end of the spring from its post.

Place retaining clip, washer, and lever into bag 7.
