Norton Bush, 2nd Gear
A 2nd gear bush for the gearbox, part number 04-0048.
This is a 2nd gear bush for the gearbox, listed under part number 04-0048. In the catalog record it shows up in the gearbox shell and gear cluster figure, which places it inside the mainshaft/gear cluster assembly rather than out on the shell casting itself.

A bush like this rides between the gear and its shaft, taking the running load so the gear itself doesn't wear against bare metal. When one of these gets worn or scored you'll usually see play or noise in that gear before anything else fails.
Our record on this part is thin - one catalog appearance, tied to 1975. If you're matching this up against a gearbox that isn't from that year, give us a call and we'll confirm before you order.
