Purpose and Function of the Window Mechanism

The presented regulator is dedicated for installation in the rear right part of the body, where it is responsible for precise window guidance and transferring power from the control system to the window's movement. The construction has been specifically designed for the Mercedes SLK R170, which translates to correct mounting points and compatibility with factory guides and seals.

The component belongs to the Window Regulators and Motors group, thus it works with the factory window control system, maintaining original operating characteristics – both in terms of movement speed and opening range.

Benefits of Using an Original Regulator

Using an original window mechanism in the Mercedes SLK R170 helps avoid problems typical of aftermarket parts, such as imprecise fit or increased play in the guides. In practice, this means:

• stable window positioning in the door frame or body,
• reduced risk of jamming and uneven movement,
• proper cooperation with seals and latches,
• maintenance of factory window closing geometry.

Thanks to this, the mechanism is particularly recommended for repairs where the goal is to maintain factory window operating parameters and minimize additional adjustments after installation.

Vehicle Placement and Installation Aspects

The regulator is intended for installation in the rear area, on the right side of the vehicle, which is important for both part selection and service planning. Correct placement on the vehicle facilitates the mechanic's identification of the part and minimizes the risk of ordering errors.

In practice, installation involves removing the trim panel in the rear part of the body, disconnecting the old mechanism, and installing the presented regulator in the existing mounting points. Thanks to its compatibility with the Mercedes SLK R170's construction, it is possible to maintain the factory window guide path and cooperate with the original lifting motor, if provided for in the specific configuration.

Part Selection by Numbers and Technical Support

The mechanism features OEM markings and interchangeable numbers, which facilitates unambiguous identification and selection of the correct variant for a specific equipment version. When selecting, it is advisable to consult catalog data or the numbers from the removed part to avoid discrepancies due to production differences.
