HDED-201: H-D Early Model
Sem 4Vintage Engines
Students will learn design, function and service for Panhead, Knucklehead, Shovelhead, Evolution®, side valve, and Iron XL engines. Topics will include valve covers and D-rings, gaskets and hardware, rocker arm and rocker bearings, intake manifold inserts, valves, guides and springs, cylinder head updates and unleaded conversion, pistons, rings, cylinder design, pushrods, gearcase covers, gears and shafts, oiling and breathing system functions, circuit breakers, lower-end flywheel assemblies, and carburetor and manifold designs.
Transmissions & Clutches
Students will learn about primary drive and clutch designs, foot clutch and mousetrap adjustment and service, kick-start mechanism designs, hand shift, ratchet top and plate-type shift fork and shaft designs, countershaft and main shaft assemblies, transmission service, three-speed and reverse differences, pushrod and throw out bearing designs, and early chain adjustments. Carburetion Students will learn the design, function, adjustment, troubleshooting and servicing of early model carburetors. Early
Chassis Maintenance
Students will learn about Springer® front-fork assembly, Big Twin Glide front forks, Sportster® Glide front forks, Star hub rebuild, ball bearing hub service, hydraulic rear-drum brake design and service, mechanical front and rear brakes, early disc brake design, and frame alignment check.
Early Electrical Systems
Students will learn electrical systems, including ignition systems (battery point, circuit breaker, magneto and early electronic). Students also will learn about two- and three-brush generators and other charging systems, early AC alternators and basic wiring.
