Gear — mainshaft second (23 teeth)
Mainshaft second gear (23 teeth) from the gearbox cluster, part number 68-3114.
This is the mainshaft second gear from the gearbox cluster, a 23-tooth gear that rides on the mainshaft inside the gearbox. It's one of the pairs of gears that make up second speed in the cluster, working alongside its matching layshaft gear to give you that ratio when you're rowing through the gearbox.
