Washer ~ wheel spindle nut (.656"=1.000"~.092")
Flat washer (.656 x 1.000 x .092 in.) fitted under the wheel spindle nut on swinging arm and rear/front wheel assemblies.
This is the flat washer that sits under the wheel spindle nut, listed in the parts books as .656 inch by 1.000 inch by .092 inch. It shows up across several figures covering the swinging arm, the rear wheel assembly, and the front brake area, which tells you this same washer gets used at more than one spindle location on the bike.

It's a simple, unglamorous piece, but it does real work: spreading clamping load from the spindle nut evenly across the fork end or wheel hub face so the nut torques up properly and stays put. The catalog carries this under 83-2266, with F12266 as the older-style number for the same washer.
Given how many different assemblies call for it, it's not a bad idea to keep a couple on hand when you're doing wheel or swinging arm work, since they're easy to lose track of or mangle when pulling a spindle apart.
