The SM 4532 is a premium, Original Equipment (O.E.) Grade Self Starter Rocker Assembly (Brush Holder) designed specifically for the Tata Winger series. Identified by the 723 series designation, this assembly utilizes a robust Lucas-style (L.TYPE) architecture with a high-capacity 4-brush configuration. It is engineered to provide the massive electrical flow and high "breakaway" torque required to crank the 2.2L DICOR and 2.0L diesel engines used in high-occupancy transport.
