Norton Gear, 3rd. Mainshaft
Third gear for the mainshaft in a Norton gearbox cluster.
04-0635 is a third gear for the mainshaft in the gearbox cluster. It's a Norton part, showing up in the gearbox shell and gear cluster records rather than anything in the Triumph line, so if you're working on a Triumph box this one isn't your part.

The catalog entry is brief and this number only turns up once, tied to a single year in our records. It sits inside the gear cluster on the mainshaft, meshing with its counterpart on the layshaft to give you third gear when you're rowing through the gearbox.
Because we don't have more detail on this one beyond the single listing, give us a call with your gearbox casting or parts book reference and we'll confirm it's the right gear before you order.
