Harley-Davidson-1971-80 FXWG-80 Parts Catalog Supplement

The Harley-Davidson 1971-80 FXWG-80 Parts Catalog Supplement is a handy reference for identifying replacement components and understanding how parts relate to each other during maintenance or restoration. For bikes in the 1971-1980 catalogue range, a supplement like this typically adds model-specific listings to the main parts catalogue. Exploded illustrations, part numbers, item descriptions, and fitment notes help you tell similar components apart and see how assemblies fit together. That's useful when checking existing hardware, preparing an order, or discussing replacement options with a parts supplier.

Unlike a workshop service manual, a parts catalogue supplement generally focuses on component identification rather than diagnostic procedures, maintenance schedules, or torque specs—those tasks usually need the appropriate service literature. Used alongside the main catalogue, this reference can help you make more informed decisions about engine-related parts, chassis fittings, controls, and other listed assemblies, depending on what the supplement covers. Confirming model applicability and any superseded part numbers before buying helps cut down on ordering mistakes. The PDF is available for download.
