New bearings for the shock linkage

[markmartin]

In the process of fitting a new chain and sprockets, I inspected the swing-arm bearings and linkage to find that 4 of the 5 bearings in the  shock relay arm were gone or going. I changed all 5 bearings and should be good to go.  Oil seals #25, bearing #26, both # 10's and both # 20's.
