Norton Pivot Spindle
Swinging arm pivot spindle for the rear suspension pivot point on the frame.
This is the swinging arm pivot spindle, the shaft the rear fork pivots on where it attaches to the frame. It's listed under Norton's own numbering, and the figure references tie it to the swinging arm, rear suspension units, and chainguard area, so it's a chassis part rather than anything to do with the engine or primary drive despite where it's filed here.

The pivot spindle is what lets the swinging arm move up and down while keeping it located square in the frame. Wear or slop at this point shows up as vague handling and rear end movement that isn't coming from the shocks.
Our catalog record for this one is thin, just the single listing, so if you're trying to match it against a specific frame or swinging arm setup, give us a call and we'll confirm before you order.
