Norton Wrist Pin
Wrist pin (piston pin) for the engine bottom end, part number 06-3842.
This is the wrist pin (piston pin) listed under part number 06-3842. The catalog places it in the crankshaft, connecting rods, pistons, camshaft, and timing gear section of the engine, so it's the pin that joins the piston to the small end of the connecting rod, letting the piston pivot as it moves up and down in the bore.

Our record on this one is a single catalog appearance from 1975, and the description doesn't spell out sizing or fit details beyond calling it a wrist pin. A catalog title we've come across elsewhere calls it out as a wristpin for an 850, which lines up with the engine-bottom placement, but we don't have that confirmed in enough detail here to guarantee it against your specific engine.
Give us a call before you order so we can confirm it matches what's in your bottom end. Wrist pins are one of those parts where getting the exact match matters, and we'd rather check than guess.
Sorry if we got something wrong here. If you think this information isn't correct, .
