Top cone and dust cover
Top steering cone and dust cover for the steering head assembly, also cataloged as H1140.
This is the top steering cone and dust cover, part of the steering head assembly where the front forks pivot in the frame. The catalog lists it under the FRAME section, and it also goes by the older H1140 designation if you're working from an earlier parts book.

The top cone sits at the upper end of the steering stem, providing the bearing race surface the head bearings ride against, with the dust cover fitted over it to help keep grit and road grime out of the bearing area. It's a simple but important piece of the steering head stack - wear or pitting here is a common cause of notchy or loose-feeling steering.
Our records show this one tied to a single catalog entry from 1966. If you're rebuilding a steering head, it's worth checking the cone and cover for pitting alongside the bearings and races themselves before you button everything back up.
