Gearchange quadrant
Gearchange quadrant that pivots inside the gearbox outer cover to work the selector mechanism.
T408/9 is the gearchange quadrant that lives inside the gearbox outer cover. It's the part the gearchange lever actually pivots against, translating the movement of the pedal into the rotary motion that works the selector mechanism inside the box.

The catalog shows this number appearing across a run of gearbox outer cover listings from 1964 through 1972, so it's been on the shelf a long time and shows up under this same number in a good number of parts-book entries. The Amal tag on this one looks off given it's a gearbox internal, not a carburetor part, so don't read too much into that.
If you're rebuilding an outer cover assembly, this is one of the pieces worth checking for wear where the lever engages it, since it takes direct pedal action every time you shift. We don't have more detail on this one beyond what the catalog shows, so if you're not sure it matches what's on your bike, give us a call and we'll confirm before you order.
