Norton Nut, Nyloc
A Nyloc locknut listed with the chaincase and hydraulic tensioner assembly.
This is a Nyloc nut, 06-0397, showing up in the catalog under the inner and outer chaincase figure along with the hydraulic tensioner listing. Nyloc nuts use a nylon insert to resist working loose under vibration, which makes them a common choice anywhere in the primary or chaincase area where a fastener needs to stay put.

The catalog record for this one is thin - it only turns up in a single figure appearance, tied to 1975 in the records we have. We don't have more detail on this one beyond the description and its place in that chaincase figure.
If you're matching this against a chaincase or tensioner assembly, best to compare the physical nut you've got before ordering, since the record doesn't give us dimensions or thread specs to check against.
Sorry if we got something wrong here. If you think this information isn't correct, .
