The auxiliary rocker arm K 28015 is a complete assembly designed to support and complement the main valve actuation system in the Sulzer ZV40/48 engine. It assists in distributing motion and forces within the valve train, ensuring balanced operation and precise control of valve movement under varying engine loads. Engineered for continuous operation under mechanical stress, vibration, and thermal influence, this component is manufactured from robust, wear-resistant materials and assembled to strict tolerances. Its integrated design ensures reliable performance and simplifies installation and maintenance. By supporting synchronized valve actuation and reducing localized stress, the K 28015 auxiliary rocker arm enhances the overall efficiency, durability, and operational stability of the engine.
