BSA SELECTOR FORK,A65 LAYSHAFT
Selector fork for the layshaft in a BSA A65 gearbox, part of the gearchange mechanism.
This is a selector fork for the layshaft in a BSA A65 gearbox, part number 68-3160 (also listed as M68-3160). It lives in the gearchange mechanism, the piece that rides in the groove of a gear on the layshaft and gets pushed by the selector mechanism to slide that gear into engagement.

The catalog places this in the inner timing cover and gearchange mechanism area, working alongside the selector camplate and quadrant to give you clean, positive gear changes. Since the description names the A65 specifically, this is a BSA part, not a Triumph one, despite it living in our vintage-Triumph-adjacent inventory.
Worn or bent selector forks are a common source of gear selection trouble - jumping out of gear, hard shifting, or a gearbox that won't fully engage. If you're chasing a shifting problem on an A65, this is one of the parts worth pulling and inspecting for wear on the fork tips.
