Performance Characteristics
1. Power Assist: It is the power source for the hydraulic steering system, generating high-pressure hydraulic fluid through engine drive, reducing the physical burden on the driver when turning the steering wheel.
2. Handling Stability: Ensures the vehicle maintains agile handling at low speeds or when turning on the spot, and provides necessary steering feedback at high speeds.
Usage and Maintenance Precautions
Usage and Maintenance Precautions
1. Fluid Management: Only use the specified type of hydraulic power steering fluid. Mixing different brands is strictly prohibited. Regularly check the fluid level to prevent damage to the pump body due to dry running from insufficient fluid.
2. System Bleeding: After replacing the pump, the system must be bled according to the procedure (usually by turning the steering wheel fully to the left and right several times). Otherwise, air will cause heavy steering or abnormal noises.
3. Cleanliness: Ensure the oil pipe joints are extremely clean during installation. Even tiny impurities entering the pump body can cause the impellers to seize or the oil seal to leak.
4. Seal Inspection: Regularly check the pump body and pipe connections to prevent air leaks that could lead to power steering failure.
