Power Steering Oil Pump Assembly
Mitsubishi FUSO®

The Power Steering Oil Pump Assembly, also known as the PS pump, is a vital part of a commercial truck's power steering system. This pump is responsible for supplying the hydraulic pressure needed to assist the driver in turning the steering wheel. The PS pump assembly is made up of several components, including the pump body, rotor, vanes, and pressure relief valve. The MB563690 PS pump assembly is designed to provide reliable and efficient performance, ensuring that the driver can easily maneuver the truck even when carrying heavy loads. The pump is driven by the engine's crankshaft and uses a belt to transfer power. As the engine runs, the pump draws in power steering fluid from the reservoir and pressurizes it, sending it to the steering gear. This allows the driver to turn the steering wheel with ease, even at low speeds. With its durable construction and precise engineering, the MB563690 PS pump assembly is an essential part of any commercial truck's power steering system.
