selectro classic hubs

Does anyone have a link to an exploded view of these Selctro classic hubs,  mine actually say Sears on them but I have been searching around the net and have been to Husky, Mile Marker, and Selectro and have found a lot of info but no pictures of how they go together.  I know, it should be obvious but I have got all of the parts sorted out and don't quite get how the spring under the cap hooks up.  Lost the instruction sheet forty years ago .

I was able to find O-rings for those.  I ordered them through Grainger, but they came from www.rtdygert.com  They are -037 silicone O-rings and come 10 to a package.  The funny little torx screw on some models uses a T-25 Torx bit that I bought in a Lisle bubble pack for a couple bucks. Hope this helps, but sounds like you got it figured out.

I ordered the internal cam piece from mile marker. They sent me plastic ones instead of my original aluminum (or whatever the metal is) ones.  They were $5 a piece.  But their minimum order was $15.  So I bought three incase I needed spairs.  Shipping was around $5.  When I checked quad 4x4 they wanted $12.95 for a metal cam, and around $15 to ship it!  So we'll see how the plastic ones hold up!  Just another option I guess for whoever is in need of the cam piece for their hubs.  I'm curiouse as to how they will hold up after my project is done.
