Harley-Davidson Transmission Parts – Gears, Shafts, Shifter Components & Rebuild Kits
Harley-Davidson transmission parts include the internal and external components used to maintain, repair and rebuild motorcycle transmissions. The selection covers transmission gears, mainshafts, countershafts, gear clusters, spacers, thrust washers, bearings, races, retaining rings and oil seals. Harley-Davidson transmission assemblies use separate mainshaft and countershaft components with individual gears, bearings, spacers and related hardware, making these parts important when servicing worn or damaged transmission assemblies. The category includes components for 4-speed, 5-speed and 6-speed transmissions across a wide range of Harley-Davidson models and generations.
Shifting components form another major part of the category, including shifter forks, fork shafts, shift drums, shifter pawls, pawl carriers, cam plates, shift links, springs, studs and shifter levers. Products such as transmission top covers, mounting plates, transmission doors, case sections, fill plugs, vent screws and mounting hardware support transmission housing and external service work. The selection also includes transmission rebuild kits, complete gasket and seal kits, individual transmission gaskets, main drive gear seals, sprocket shaft seals and replacement bearings for different Harley-Davidson transmission configurations. Harley-Davidson service documentation identifies shifter fork shafts, shifter forks, mainshafts, countershafts and multiple gear assemblies as distinct transmission service components.
The category also covers older and specialized transmission components, including kick starter parts, kick-start shafts, gears, springs, ratchet components, conversion kits, jockey-style transmissions and 4-speed transmission assemblies. Applications range from early WL, EL, UL, FL and Servi-Car models through Sportster, Dyna, Softail and Touring motorcycles, with later 5-speed and 6-speed components covering newer transmission designs. Transmission hardware, fasteners, thrust washers, spacers, seals and bearings can be used alongside internal gear and shaft components during a transmission rebuild, while shifter and kick-start parts address the external controls and mechanisms used to operate different Harley-Davidson transmission configurations.
