KICKSTART BUSHING 650/750 TRI
Kickstart spindle bushing for Triumph 650/750 twin and triple gearboxes, PN 57-0023 (also T23).
This is the kickstart bushing for Triumph 650 and 750 twin and triple gearboxes, part number 57-0023, older parts books list the same piece as T23. It's the bush the kickstart spindle rides in as it passes through the gearbox cover, letting the lever swing and return without the spindle wearing away the cover casting itself.

You'll find it referenced across the gearbox outer cover and gearbox inner cover and selectors sections of the parts books, which tells you it sits right at that spindle bore where the kickstart shaft comes through. It shows up in catalog listings from the mid-1960s through 1980, so it's a long-running part across that gearbox family.
This is one of those small wear items that's easy to overlook until the kickstart lever starts feeling sloppy or the spindle starts chewing up the cover bore. Worth checking the fit against your existing cover before installing, and if you're doing the kickstart shaft, take a look at the matching gear change spindle bush too since they live in the same area.
