During diassembly of my secondary on my 06 900 which I believe is the TSS-98 (has the 8 screw helix) I noticed that the washer that goes between the two sheaves is dished or tapered. Because the belt-deflection allen screw had worn a groove in it, I figured I'd go ahead and replace it. The new washer that I recieved from Carls is flat. I've taken crappy cell photos to show the difference. Does anyone know if they are suppose to be flat or should it be replaced with another dished washer/spacer???
