My 32 Blue Star came to me in many pieces. Included was a box of clutch parts, containing bits from more than one bike. I have sorted most of the parts for the BS clutch,
and I think I'm almost there, but I am stumped by the fact that according to the parts book I need 6 fibre plates, 2 metal driven plates, and 2 metal driving plates. It seems to me that 5 fibre plates would be the correct number, but this formula persisted in later parts books. Can anyone offer guidance on the 6th plate, or am I missing something again? The only diagram I can find of a complete clutch is for the Empire Star in the 1936 parts book (p147), and calls for 8 fibre, 3 driven, and 4 driving, for a total of 7 metal plates and 8 fibre, which looks right, with the sliding plate on top of the 8th. fibre plate. Does a drawing of the BS clutch exist?
Also, in said box, I have two sliding plates with 4 studs and a recessed centre for the spring, but the recess is deeper on one than the other, any idea of the correct depth?
Thanks, Les
