BSA Spacer — clutch retaining nut
Spacer used with the clutch retaining nut in the primary chaincase clutch assembly.
This is a spacer that sits with the clutch retaining nut in the primary chaincase assembly. It's a small, easy-to-overlook piece, but it's part of what keeps the clutch center properly located and the retaining nut torqued up against the right surface rather than bottoming out somewhere it shouldn't.

It shows up in the parts books under the clutch and primary cover figures, so this is one you'll be pulling into view when the primary chaincase is off and you're into the clutch itself. Given how it's cataloged, it's worth having on hand any time you're servicing the clutch center or replacing the retaining nut so you don't end up chasing a stack-up problem after reassembly.
Our catalog record on this one is brief — it doesn't tie it to a specific model, just to the clutch and primary cover area across a run of appearances from the late '60s into the early '70s. Call the shop and we'll confirm fitment before you order.
