  1. The main reason why the chain and or clutch rub on the case is because usually there are a number of spacers missing or the bracket are in the incorrect position. The idea is that as you adjust the primary chain by moving the gearbox, the circular disc in Rons pic moves back and forth with the main shaft, thus maintaining a seal (ish). The disc you see is one of two, the second being on the back of the case. These 2 discs are sandwiched over a seal, possibly cork or leather (rubber would work better) and secured by rivets (I've seen them welded).

     

     

    Hi Chris

     

    I assume it is a flat seal under the disc which sits on the outside of the case? I had the two discs crudely rivetted together on the case but no evidence of a seal.
