Samwel Transmission Parts

30 products — part of all Transmission Parts

Samwel transmission parts are purpose-built for the vintage Harley-Davidson restorer, covering the gearbox components that are hardest to source for the oldest machines in the V-twin world. Samwel's focus on reproduction and replacement parts for classic Harley-Davidson motorcycles means their transmission catalogue reaches well beyond the mainstream, with parts for the 45-inch Flathead spanning models from 1937 through to 1973 — a range that encompasses the legendary WL, WLC, and servi-car era through to the final years of the Flathead engine's remarkably long production run. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks Samwel parts to support UK owners of these historically significant machines who need a reliable source for components that are no longer produced elsewhere. Rebuilding a Flathead transmission requires parts manufactured with the right materials and correct dimensions, and Samwel specialises in filling exactly those gaps. Whether you are returning a wartime WLC to running condition, completing a ground-up restoration of a WL, or keeping a late-model K-series descendant shifting correctly, Samwel understands the precision and authenticity that vintage Harley-Davidson work demands. For anyone serious about vintage Harley-Davidson restoration, their transmission range is indispensable. Browse the full Samwel Transmission Parts range below.
