Honda-SOHC

I have a 1971 Honda CB500.  I'm new to the rebuilding world, but I love tinkering in the garage.  So I removed the LH crankcase cover to my bike the other day, no problems getting it off.  But when I reinstalled it, the hand lever cable was not engaging the clutch to allow me to shift gears.  I never adjusted anything inside the cover, but I didn't do something right when assembling.  When I pull the lever everything seems to be working inside the cover.  I did have several (maybe 6) small 1/4" orings that fell out of the cover, broken, when I removed it.  I'm not sure where they go.  My manual doesn't spec them out anywhere.  Any ideas how I may have mis-assembled the cover?
