Norton Gasket, Pump to Crankcase
Gasket that seals the oil pump to the crankcase on a Norton engine.
This is the gasket that seats between the oil pump and the crankcase, listed in the catalog as Gasket, Pump to Crankcase. It's a Norton part, not a Triumph one, and it shows up in the engine timing/oil pump area of the parts book alongside the contact breaker, timing cover, and oil pressure relief valve.

Its job is simple: keep the mating faces sealed where the oil pump bolts up to the crankcase, so oil stays in the pressure circuit instead of leaking out at the joint. It's a thin, one-piece item and gets replaced whenever the pump is pulled for service.
Our catalog record only ties this to a single year, so if you're matching it against an older or later engine, give us a call and we'll confirm fitment before you order.
