BSA Shim, crankshaft (.005")
A .005 inch crankshaft shim from the 1969 CYLINDER AND CRANKSHAFT parts book listing.
This is a crankshaft shim listed at .005 inch, appearing in the CYLINDER AND CRANKSHAFT figure of the parts book. Shims like this are used to set end float or take up clearance on the crankshaft assembly during a rebuild - a thin spacer that lets you fine-tune the fit without swapping out larger parts.

The catalog only shows this one appearance, for the 1969 model year, and the description doesn't tell us which specific engine or model it was fitted to beyond that. If you're rebuilding a bottom end and need to shim the crank to spec, this is worth having on hand, but check your own measurements and figure references before ordering to make sure it's the right thickness for the gap you're closing.
It also goes by 40-65 in some catalog listings, same part, just the shorter number form.
