Norton Engine Sprocket Key
A small drive key that locks the engine sprocket to its shaft so it can't rotate independently.
PN · NME3682
NME3682 is the key that locates the engine sprocket on the crankshaft or gearbox mainshaft, keeping the sprocket from spinning independently of the shaft it's mounted on. It's a small but important piece in the primary drive area, working alongside the sprocket, chain, and clutch assembly to transmit power reliably.
