The SM 6139 Starter EGT (Epicyclic Gear Train) Gear Ring is a heavy-duty stationary internal gear specifically engineered for the Lucas-style (L. Type) reduction starter motors used in Bharat Benz commercial vehicles. This high-tensile ring gear acts as the outer track (annulus) for the planetary gear system, enabling the high-torque multiplication necessary to crank the advanced 4-cylinder and 6-cylinder engines found in the Bharat Benz truck and bus range. Precision-machined from reinforced, heat-treated alloy steel, this component is designed to withstand the extreme radial forces and mechanical stress of heavy-duty haulage.
