Norton Cap, Clutch Adjuster
Clutch adjuster cap for the primary chaincase, from the inner/outer chaincase and hydraulic tensioner assembly.
This is the clutch adjuster cap that sits in the primary chaincase, part of the assembly covering the inner and outer chaincase along with the hydraulic tensioner setup. Our catalog record on it is thin, one entry tied to 1975, and it doesn't tell us more about what the cap is made from or exactly how it seats.

Given the figure it comes from, it's associated with the clutch adjustment area inside the primary drive housing, keeping things sealed up while giving access to the adjuster. If you're chasing down this cap for a rebuild, it's worth calling ahead so we can confirm it matches what your chaincase actually needs.
This part shows up under Norton records, so don't assume it interchanges with Triumph primary covers just because the location on the bike sounds similar.
