ROTOR NUT,NORTON
A rotor nut for Norton engines, securing the alternator rotor on the crankshaft end.
This is a rotor nut for a Norton, not a Triumph part despite whatever number sequence it turned up under. It secures the alternator rotor on the end of the crankshaft, keeping the rotor from working loose as the engine runs. The Lucas tag attached to this listing is off base - a rotor nut is a mechanical fastener, not an electrical component, so don't read too much into that.

Our catalog record on this one is thin. We don't have model-year specifics tied to it beyond what the description tells us, so if you're matching it to a particular Norton, check the thread and stack it up against what's on your crank before you order.
Call the shop if you want us to confirm fitment on your specific machine before it ships.
