Clutch Complete
Complete clutch assembly for the primary drive, listed in the parts books as 57-1933 (formerly T1933).
57-1933 is the complete clutch assembly listed under the CLUTCH figure in the parts books, carrying the older T1933 number in earlier catalog printings before Triumph moved to the numeric-only scheme. It's the full clutch unit as sold as one assembly rather than a single component, so when the parts book calls for it, you're getting the whole set-up rather than a plate, spring, or basket on its own.

Catalog listings for this part run from 1964 through 1966, which tells us the years it shows up in the books we've checked, though we'd want to confirm exact fitment against your particular machine before you order. If you're rebuilding a primary and need the clutch as a unit rather than piecing it together part by part, this is the number to work from.
Give us a call if you're not sure whether your bike's primary case and clutch basket match up with what this assembly includes. We can walk through what's in the box before you commit to it.
