The SM 6127 Starter EGT (Epicyclic Gear Train) Gear Set is a high-precision internal component kit specifically engineered for Lucas-style (L. Type) reduction starter motors used in agricultural and commercial vehicles. This set of three planetary gears is precision-machined to facilitate efficient torque multiplication within the starter's reduction assembly, providing the mechanical leverage required to crank high-displacement diesel engines. Manufactured from high-tensile, heat-treated alloy steel, these gears offer exceptional resistance to wear and tooth-shearing under heavy agricultural and haulage loads.
