BSA Spindle — oil pump driven gears
Spindle for the driven gear inside the oil pump, from the gearbox sprocket area of the engine.
71-1146 is the spindle that carries the driven gear inside the oil pump assembly. It shows up in the parts book under the oil pump and gearbox sprocket figures, so it lives down at the pump end of the engine where the oil pump gears are housed near the gearbox sprocket area.

The catalog record has this part appearing across a run from 1970 to 1972, but it doesn't spell out which specific models it was fitted to beyond that. If you're rebuilding an oil pump and the driven gear is loose or worn on its shaft, this is the spindle that gear rides on.
Give us a call if you want to confirm this matches what's in your pump housing before you order — the catalog entry here is brief and we'd rather get you the right part than guess.
