When I bought this pile of parts, I hoped to learn about how motorcycles are built and run, learn some history about Harley and enjoy a hobby totally unrelated to how I earn a living. So far, I'm happy to report, the project is living up to expectations. When I bought what was advertised as an all original 1958, I was skeptical. As I clean and catalog these parts, I'm researching as well and have revealed much of this bike to be from years other than 1958. Again, no big deal-it was expected and the investigation is what is teaching me the most about it.
The engine is a 1958 as it is stamped with a number which proves it to be so. The frame is consistent with the frames first used in 1958 but, Harley used this frame on it's Duo-Glides until 1964. 1958 was the first year of the Duo-Glide. In previous years the rear wheel attached directly to the frame. The Duo-Glide frame introduced the swingarm to the back end of the motorcycle which allowed the bumps in the road to be absorbed by the shock absorbers attached to either side rather than the lower back of the rider. The frame is known as a "step down" frame.
While the swingarm has all the markings consistent with a 1958 -1961 swingarm, it also has a zerk fitting (for greasing the swingarm pivot bolt) which places it squarely in 1962. As the components were seperate when purchased and knowing that most of the parts are interchangeable for years and years, I can not be sure if the entire frame is a 1962 or if it's just the swingarm.
