Norton Chain, Primary (Front)
Front primary chain, catalog number 06-0366, listed in a 1975 catalog entry under the gear linkage and chains figures.
This is the front primary chain, listed in the catalog under 06-0366 and pulled from figures covering the gear linkage, chains, alternator, and engine sprocket area. The primary chain runs between the engine sprocket and the clutch, carrying drive from the crankshaft through the primary case, so it sits between the alternator and the gearbox input in that part of the machine.

The catalog appearance we have on file for this number is dated 1975, which puts it in the later end of the range for this style of primary drive. Beyond that single entry we don't have much else to go on for this part number.
The manufacturer tag on this one reads Norton in our records, but a chain of this type is a generic wear item rather than something unique to one marque, so don't put too much weight on that tag by itself. Call the shop and we'll confirm fitment before you order, especially since the only catalog listing we have doesn't tie it down beyond that one year.
