A primary gasket like this seats between the primary chaincase and the engine or inner cover, sealing the oil bath that keeps the primary chain running wet. It's a thin, one-time-use item — once you pull a primary cover for chain adjustment or clutch work, plan on a fresh gasket going back in rather than reusing the old one.
If you're working on a 3T or TR5 and need this gasket, give the shop a call and we'll confirm it matches what's on your primary cover before you order.
