| + | Below are some suggestions for manuals for your ride. \\ | ||
| + | __You should have, at minimum, a Factory Service Manual (FSM) and a Factory Parts Catalog for your year model__. \\ | ||
| + | |||
| + | **Factory Service Manuals (FSM)**; \\ | ||
| + | The FSM will have the most accurate information, | ||
| + | Clymer and Haynes make service manuals also for Sportsters but some of the information is in error to the factory FSMs. \\ | ||
| + | And some of the information in the aftermarket manuals is vague in information or procedures but they may have more pictures. \\ | ||
| + | So it is generally said you can get use from both an aftermarket manual and the factory service manuals but get the factory manual first. \\ | ||
| + | [[techtalk: | ||
| + | |||
| + | **Parts Catalogs**; \\ | ||
| + | The Parts Catalog has part numbers of course but it also has exploded parts views. \\ | ||
| + | However, IT IS NOT INTENDED TO BE AN ASSEMBLY MANUAL. \\ | ||
| + | And some of the exploded views are confusing or not related to each other on the same pages. \\ | ||
| + | But, all in all, the exploded views do help finding what goes where. \\ | ||
| + | Most of the fasteners listed in the relevant parts catalog individual pages have thread sizes and lengths also in case you need those. \\ | ||
| + | **Note: ALL 1957-1978 PARTS CATALOGS LIST PARTS FOR PREVIOUS YEARS**. \\ Below is a simple list of original and " | ||
| + | The in-between year books may show different part numbers for the same year model bike. \\ | ||
| + | [[techtalk: | ||
| + | (complete list of other parts catalogs and supplement catalogs that pertain to each year model on the bottom of that page) \\ | ||
| + | Some often acquire several year model parts catalogs and that page will help you decide which ones are right for you. \\ | ||

| + | ===== The Ironhead Multi-Year Parts Catalog Curse ===== | ||
| + | Below is a summary of an article on the Sportsterpedia Parts Catalogs page regarding parts book errors. \\ | ||
| + | You can also read the full article from this link: [[techtalk: | ||
| + | Due to all of the errors and non corrected editions, it's always a good idea to acquire several year parts catalogs surrounding your year model. \\ | ||
| + | Which year catalogs you'll need will depend on many factors but the main Parts Catalog page in the Sportsterpedia will help you decide which ones you need. \\ | ||
| + | [[techtalk: | ||
| + | |||
| + | * Not all multi-year catalogs will list factory installed parts on your bike. | ||
| + | * You may need several year catalogs to determine factory installed parts for your year model. | ||
| + | * Some parts first appeared or only appeared in Parts Supplements, | ||
| + | * Later catalogs may show parts for older models that were never factory installed on them. | ||
| + | * Some catalogs have missing parts and/or missing models in some parts listings. | ||
| + | * Some illustrations do not have a part number listed. | ||
| + | * Drawings may or may not look like your part number. | ||
| + | * Some exploded parts diagrams show the assembly in the wrong order or missing pieces. | ||
| + | * There may be misleading information about parts that fit your year model. | ||
| + | * Fastener lengths and thread pitch may change depending on catalog used. | ||
| + | * The MoCo knew about and tried to correct at least some of the parts catalog mistakes. | ||
