Purpose and function in the vehicle

The offered hydraulic pump is a component of the system responsible for operating the tailgate in Mercedes ML W164 family models. Mounted in the rear area, it works with hoses and actuators, generating the appropriate operating pressure to open and close the tailgate. Using a dedicated solution allows for maintaining the correct operating characteristics – from a smooth start, through uniform movement, to stable closing.

In practice, this translates into:

• consistent operation of the tailgate lifting system,
• maintaining the convenience of using the luggage compartment,
• reducing the risk of mechanical overload in hinges and actuators.

Benefits of using an original hydraulic pump

Using a pump dedicated to the ML W164 series allows for maintaining operating parameters in accordance with the manufacturer's specifications. The tailgate hydraulic system is precisely tuned, which is why using the correct component promotes stability of the entire system's operation. This is especially important in vehicles equipped with electric tailgate control, where proper cooperation between the pump, actuators, and electronics affects safety and ease of use.

The main advantages of such a solution include, among others:

• maintaining the factory movement characteristics of the tailgate,
• reducing noise and vibration during system operation,
• better protection of mechanical components against excessive wear.

Condition, verification, and preparation for installation

The pump comes from disassembly and is offered as a used original component. Such components are frequently chosen for tailgate hydraulic system repairs because they allow for maintaining structural compliance with the vehicle's factory equipment. Before installation, it is recommended to perform a standard inspection of the hydraulic system and the correctness of hose mounting to ensure the tightness and proper operation of the entire system.

Due to the nature of the component, it is worth entrusting the installation to a workshop with experience in servicing hydraulic systems in Mercedes vehicles, which facilitates proper bleeding and system configuration.

Application in the rear body section

The placement of the pump in the rear zone of the vehicle promotes compact hose routing and limits pressure losses in the system. This solution is particularly important in SUV-type vehicles, where the tailgate has a large surface area and weight. A properly selected hydraulic pump supports uniform lifting and lowering of the tailgate, which improves daily ergonomics and facilitates access to the cargo space.
