Norton STARTER SPRAG CLUTCH 18 ROLLER ANDOVER - USE ONLY WITH NEW GEAR AND SPROCKET - 69.0617
Starter sprag clutch, 18-roller design, for use only with a new gear and sprocket, not a worn set.
This is the starter sprag clutch, an 18-roller sprag bearing used in the Andover-built electric start setup. It's the one-way clutch that lets the starter motor spin the engine over without the engine trying to spin the starter back once it fires. The catalog notes are specific on this one: use it only with a new gear and sprocket, not with worn originals, so if you're replacing the sprag on a tired starter drive, budget for the mating gear and sprocket at the same time.

The part carries the number 064733A here, also shows up as 06-4733 in older listings, and it's the same physical piece under either number. If your parts book lists 069.0617 or references the Andover electric start assembly, this is that component.
We don't have model-year specifics on file for this listing beyond what's in the description, so confirm fitment against your bike's parts book before ordering, especially since the note about pairing it with new gear and sprocket suggests some engineering tolerance stacking you don't want to get wrong.
