Purpose and function of the actuator

The presented actuator is responsible for the mechanical movement of the door lock latch in the rear doors, working in conjunction with the central locking system in the Mercedes W124. The component is prepared for installation on both the left and right rear sides, which facilitates selection during locking system repairs. By maintaining the factory design, it ensures proper compatibility with original locks and the vehicle's electrical system.

Construction and fitment for the Mercedes W124

The actuator has been designed specifically for the door architecture of the Mercedes W124, taking into account rod routing, mounting points, and the latch's range of motion. Proper fitment to the rear of the body allows for:

• stable mounting in factory mounting points,
• proper cooperation with the lock mechanism and latch,
• maintenance of the working stroke intended by the manufacturer.

Such fitment limits the need for installation modifications and allows for the preservation of the original operating characteristics of the central locking system.

Scope of application and installation configuration

The actuator is intended for installation in the rear part of the vehicle, with the possibility of installation on both sides of the body. This facilitates service when it is necessary to replace the component on the left or right side, and also allows for maintaining the consistency of the entire locking system's operation. Proper placement on the vehicle promotes correct cooperation with the wiring harness and the locking mechanism.

Performance characteristics of the used component

The offered actuator comes from disassembly, which allows for maintaining the original manufacturer's specifications and fitment for the Mercedes W124. A used component of this type is often chosen for repairs of classic models, where compliance with the factory design and the possibility of economical replacement of a faulty subassembly are important. Before installation, it is recommended to perform a standard check of the central locking system to eliminate additional sources of failure.

Support in selection and other elements from the locks group

In case of doubts regarding the fitment of the actuator to a specific body version, it is worth using the OEM number and interchangeable numbers available in the technical specification, as well as comparing the construction with the currently installed element.
