DUST COVER 1943-54 FRONT WHEEL - Replaces 37-1654
Wheel bearing dust cover, PN 37-0583 (W583), tied to factory number 37-1654.
This is a dust cover for the wheel bearing, part number 37-0583, also known by the legacy code W583. The catalog description ties it to the front wheel and the years 1943-54, though the figure title in our own records places it under REAR WHEEL, so it pays to check which end of the bike your parts book is calling out before you order.

A dust cover like this sits over the wheel bearing to keep road grit and moisture off it, which keeps the bearing running longer and keeps grease where it belongs. This number is tied to 37-1654 as a factory supersession, so if your parts book lists 37-1654 instead, you and the counter are talking about the same physical piece.
This one shows up thin in our own catalog records, just a single listing, so if you have questions about which wheel or which years it's right for, give us a call and we'll sort it out with you before you commit to an order.
