This hydraulic hose assembly carries pressurized oil within the combine’s hydraulic system. It connects components in the hydraulic circuit, transmitting fluid to actuators that control machine functions. A cracked or leaking hose reduces system pressure, causing sluggish or incomplete implement movement. The assembly is built to the original manufacturer’s specifications for hose diameter, fitting orientation, and crimp strength, ensuring it matches the routing and connection points of the original line. When replacing, inspect the mating ports for debris and torque the fittings to the specified value.
