Layshaft 2nd gear (26T)
Layshaft second gear (26 tooth) for the Triumph gearbox internal cluster, current equivalent of the older 57-1065.
This is the layshaft second gear, a 26-tooth gear that lives inside the gearbox on the layshaft, working alongside the mainshaft gears to give you second gear. It's part of the internal gear cluster shown in the gearbox shafts and gears section of the parts book, and it's the kind of part you're only pulling out when you're rebuilding the box or chasing a gear selection problem.

Catalog appearances for this part number run from 1969 to 1972, and it carries the legacy number T3861 if you're working from an older book. It also shows up as a replacement for the earlier factory number 57-1065, so if your parts book or an older box has that number stamped or listed, this is the current equivalent.
When you're in there for a gearbox rebuild, it's worth checking this gear along with its mating gears for wear on the teeth and the bore before you put it back together. If you're not sure which gear position you're dealing with, give us a call and we'll help confirm before you order.
