KICK PAWL 350 500
Kickstart pawl for Triumph 350 and 500 unit twins, part of the kickstart engagement mechanism in the gearbox.
This is the kickstart pawl for Triumph's unit-construction 350 and 500 twins, part number 57-1431, also known under the older T1431 form. It shows up in the parts book under gearbox shafts, bearings and inner cover, which tells you it's inside the transmission end of the engine, working as part of the kickstart mechanism.

The pawl is the small piece that engages when you swing the kickstart lever down, catching the mechanism so the motion turns into rotation of the low gear in the transmission. When a pawl wears out or its engagement edge rounds off, the kickstart can slip or fail to catch cleanly, which is usually the first sign something in this area needs attention.
This one is listed once in the catalog data we have, tied specifically to the 350 and 500 unit twins. If you're not sure whether your gearbox uses this exact pawl versus a similar-looking part from another model line, give us a call before ordering and we'll confirm fitment.
