The SM 6136 Starter EGT (Epicyclic Gear Train) Gear Set is a heavy-duty internal component kit specifically engineered for the high-capacity Lucas-style (L. Type) reduction starter motors used in premium heavy commercial vehicles. This configuration features a set of four planetary gears, providing the maximum surface area contact required to distribute the massive rotational torque needed to crank the high-displacement Cummins and Tata ISBe engines found in the Prima series. Precision-machined from high-density, heat-treated alloy steel, these gears are built for extreme industrial durability.
