Norton Spindle, Rocker
Rocker spindle for the Norton Commando valve gear, sold individually.
This is the rocker spindle out of the valve gear on a Norton Commando engine. The rocker arm pivots on this spindle up in the cylinder head, and it's a wear part - the surface the rocker rides on takes a beating over the years, so if you're finding play or knock in the valve gear this is a likely spot to check.

Our catalog record ties this one to 1975 appearances, and the part is listed as sold individually rather than as a pair, so check how many you need before ordering. Pulling a stuck spindle can be a fight - there's a dedicated extractor tool for this job, worth having on hand rather than improvising something that'll mark up the head.
If you're working through a full valve gear rebuild, plan on going over the rocker arms themselves and the bushings while you're in there, since spindle wear usually isn't happening in isolation.
