I am restoring a BSA B33 rigid, pre unit, 500cc, 1954 and am left with a metal washer which I cannot remember where to fit.
The dimensions are: outer diameter - 35.04 mm (1 3/8"?)
inner diameter - 25.5 mm (1"?)
thickness - 2.3 mm (1/11"?)
The inner diameter is a bit oval so it must have seen a lot of use on an axle or similar. Could be from the gear box main shaft or from the clutch.
Can anyone identify this part?
