About This Product
This Samwel Supplies lower end part is a dedicated replacement for the 45CI Sidevalve and Flathead Big Twin engines. It is designed to fit 45CI models from 1937 to 1973, including the Servi-Car, and also fits the 1937 to 1948 Flathead Big Twin models. Built to replace OEM 24675-37, this component is essential for maintaining the structural and mechanical health of your vintage bottom end. Samwel parts are known for their accuracy and durability, which is exactly what you need when dealing with the tolerances of these older engines.
