The manual power steering rack features a straightforward design, offering a simplified engineering process and high transmission efficiency. It operates with fully sealed components, ensuring reliability. This type of steering gear has been widely adopted in foreign markets for many years. However, its application is somewhat limited due to its low transmission ratio, making it more suitable for smaller vehicles. In this system, the end of the steering shaft is connected to a cylindrical gear, which engages with a rack housed within the vehicle's frame. The rack is connected to two tie rods through ball joints, which directly control the movement of the wheels, enabling the car to steer.
The Principle of Power Steering Gear
The Corolla power steering rack is a hydraulic system that utilizes engine power to assist in steering the vehicle. In this system, the engine drives an oil pump that generates hydraulic pressure. This pressure is then applied to a power cylinder piston, which in turn provides additional force to the pinion, assisting the rack in steering the vehicle. The amount of assistive force is directly related to the pressure on the piston; when more steering power is required, the hydraulic pressure is increased. This pressure is regulated by a control valve connected to the steering shaft, ensuring smooth and responsive steering.

The Structure Principle of Power Steering Gear
The Toyota Corolla power steering rack, specifically the 45510-02490 model, features a rack and pinion design. At the back of the pinion, there is an adjustable semicircular component. This component is pressed against the rack by a spring, ensuring that the rack maintains proper contact with the pinion under the right amount of pressure. The adjustable semicircle, along with the spring, plays a crucial role in minimizing any gaps within the steering mechanism, ensuring smooth and precise steering performance.

Care and Maintenance
1.For new power steering kits,please change the automatic gear oil after first running 2500km.Afterwards please change the oil and clean the oil tank for each 50000km running or each year.
2.Please check the oil lever and oil quality each month and fill the oil to the right lever.If you find the oil with many dirties,please change it.
3.Always check and maintain the tire pressure be in accordance with the provisions.
4.The procedure of changing oil or refueling
(1)Put up the epipodium.
(2)Open the lid;unscrew the bolt on the oil outlet and discharge the bottom oil(in idling state).And turn the steering wheel to the limit in both directions for several times until no oil left in the oiler.
(3)Tighten up the bolt on the oil outlet (to keepit clean and in case of dirties).
(4)Refuel in the oiler.
(5)When the car in idling,turn the steering wheel to the limit in both directions for several times until the oil level is stable and no bubble produced.
(6)Refuel until it reaches the mark.
(7)Tighten the oiler lid.
