Screw the stud with the spring around the flat part into the machine, put pin in.
Then follow in the order that you have it laid out
The discs will go in the loop part of the check spring facing like ) (
The following items will go on with the bar across and spring end that will fit in the slot of the stud.
Next put the disc that has the bar across with the bump facing the end of the stud that is outside of the machine.
The beehive spring goes on next with the large end toward the machine and small end out.
Then the nut goes on.

Do you have a brush that will fit the center of the stud, so that it is cleaned out of gunk? Maybe a pipe cleaner would work, too, to brush back and forth?

Hope this helps.
