Norton Gasket, Inner to Outer Cover
Paper gasket sealing the gearbox inner to outer cover on a Norton.
This is the gasket that seals between the gearbox inner and outer cover on a Norton. It's a thin paper/fiber seal that keeps oil in the gearbox shell where it belongs and out from between the two cover halves.

The catalog record for this one is brief, tied to a single figure titled Gearbox: Inner Cover, but that lines up with what the description says: it's the seal that goes between the inner and outer covers on the box. Cheap enough to replace any time you've got the covers off, and not something to reuse once it's been compressed and pulled apart.
This is a Norton part, not a Triumph one, despite showing up filed here with our Triumph inventory. If you're working on a Commando or Atlas gearbox and pulling the outer cover, this is the gasket you want on hand before you button it back up. Give us a call if you want to confirm it matches what's on your bench.
