BSA CRANKSHAFT SHIM SET A65
Crankshaft shim set for the BSA A65 engine.
This is a crankshaft shim set for the BSA A65, listed in the catalog under crankshaft and crankshaft/pistons figures. Shims like these are used to set the running clearance of the crankshaft in its cases, taking up the gap between components so the assembly runs true once torqued down.

The part carries the number 68-0633 in current listings, with 68-633, 97-0304F, and H304F showing up as earlier or alternate catalog forms of the same set. The catalog description names the A65 specifically, so this is a BSA part, not a Triumph one, even though it shows up in a shop that deals mostly in Triumph iron.
Our catalog record ties this to appearances between 1969 and 1972. If you're rebuilding a bottom end and need to know exactly which shim thickness or how many pieces come in the set, call the shop and we'll confirm before you order.
