Norton GEARBOX ADJUSTER EYE BOLT
The eyebolt used in the gearbox adjuster assembly for pulling the gearbox back on its mounting to set chain tension.
This is the gearbox adjuster eye bolt, part number 062657 (also stamped 06.2657 in some records). It shows up in the gearbox figure covering the shell, gear cluster, mounting bolts, adjuster, and countershaft sprockets, so its job is tied to setting up the gearbox mounting and chain adjustment rather than anything inside the gear cluster itself.

The catalog listings call it out plainly as the eyebolt for the gearbox adjuster assembly - the part that lets you draw the gearbox back and forth on its mounting to take up slack in the primary or final drive chain. It's a small but important link in that adjustment chain, and one that's easy to overlook until it's worn or bent.
Our records show this one appearing across catalog entries from 1971 to 1973. We don't have more detail on it beyond that, so if you're matching it up to a specific gearbox casing or adjuster kit, check the fit against what you've got before you order.
