GEAR MAINSHAFT 2ND CR
Mainshaft second gear for the unit-construction Triumph gearbox, catalog number 57-1832.
57-1832 is a mainshaft second gear from the gearbox internals, listed in the parts books under the older T1832 number as well. It shows up in the GEARBOX SHAFTS, BEARINGS AND INNER COVER figure, so it lives inside the transmission case, riding on the mainshaft where it takes the shift into second.

Our catalog data has this one appearing across rows from 1966 through 1970, which tells you it was in production use through that span, but we'd want to confirm your specific gearbox casing and internals before you order to make sure the mainshaft and gear cluster match up.
If you're rebuilding a box and pulling the shaft assembly apart, it's worth inspecting the dogs and bore on this gear closely alongside the rest of the cluster while everything's out.
