DZ9112340140 Engine Brake camshaft (right) SHACMAN Truck Parts

    Part number DZ9112340140 right-side engine brake camshaft is a precision-machined core component tailored for SHACMAN truck engine braking systems, acting as the critical power transmission part that converts hydraulic pressure into mechanical motion to trigger the engine brake mechanism. Its core function is to precisely control the opening and closing sequence of engine valves during braking operations, boosting the truck’s retarding force to alleviate the load on the service brake system—this is particularly vital for heavy-duty trucks navigating long downhill slopes and transporting bulky cargo.Crafted from high-strength alloy steel and treated with a quenching and tempering process, the camshaft boasts outstanding hardness, wear resistance, and fatigue strength, enduring high torque and continuous mechanical stress in extreme working conditions. Its precisely ground cam profile ensures smooth, stable operation and consistent braking performance, while the anti-corrosion surface coating effectively resists rust and oil contamination.Manufactured to strict SHACMAN OEM standards, this right engine brake camshaft ensures seamless compatibility with matching truck models, allowing for direct replacement without modifications. As a key safety component, it enhances the truck’s braking stability, cuts down maintenance costs, and maximizes operational safety for long-haul fleets.
