I searched the forums and reviewed the Shimano tech sheets, but can't find an answer to this.
I have a Shimano Sl-8S20 Revoshift for a shimano 8speed IGH. I'm installing the old system on a new frame, and decided while I was at it, to replace the cable.
Following the directions on the tech sheet, I unscrewed the screw and removed the top cover to access the cable housing and the stopped end. When I removed the screw and the cover, two little springs popped out. These tiny springs (1/8" dia) each have a "leg"on them, One leg is longer than the other, and one spring is longer than the other. My hunch is that they nest together with the "legs" about 120 degrees apart. However, I cannot for the life of me figure out WHERE they go.
They're not shown or mentioned on either the revo-shift specifictech sheet, or anywhere on the overall IGH tech sheet.
This is not the spring which provides the resistance for the adjustment barrel.

I can re-assemble the unit without them, and it seems to otherwise work...
I'm wondering if it's safe to leave them in the mystery left over parts drawer, or if they're vitally important in some way I don't understand.
