Harley-Davidson schematics & diagrams database

478 engineering drawings Harley-Davidson filed with the US Patent Office from 1910 to 2025 — frames, engines, transmissions, brakes, electrics, luggage and more — plus the public-domain WWII Army manuals for the WLA. Search by part, system or year, open any drawing full size, and shop the parts for that system.

What's in here, and what isn't. Everything below is genuinely public: granted US patents are public records, and the Army manuals are US government works. The wiring diagrams and exploded views in Harley-Davidson's own service manuals and parts catalogues are copyrighted and sold by H-D dealers — for model-specific wiring, torque and specs, buy the factory service manual for your exact model and year. Owner's manuals are free from Harley-Davidson's own website.
