Distance piece (outer)
Outer distance piece / spacer for the rear wheel and speedo drive on quickly-detachable rear wheel setups, PN 37-1477.
This is the outer distance piece for the rear wheel on quickly-detachable rear wheel setups, part number 37-1477 (also stamped W1477 in some records). It's a spacer that lives on the rear axle where the speedometer drive sits, keeping the wheel and speedo drive components positioned correctly on the spindle.

The catalog shows this piece appearing across both the standard rear wheel figure and the quickly-detachable rear wheel figures, including a QD variant noted as not for U.S.A. spec machines, so the exact wheel configuration on your bike matters when ordering. It shows up in catalog rows spanning 1964 through 1974, which tells you it had a long production run, but that's not the same as saying it fits every bike in that window.
It's a small, easy-to-overlook part, but if it's worn, cracked, or missing, the rear wheel won't sit right on the spindle and the speedo drive can end up misaligned. Worth checking against your own wheel and axle before you order — call the shop if you're not sure which rear wheel setup you've got.
