A. 3-Lug Spring Compressor





A new 3-lug spring compressor is available (Figure 1). The compressor is supplied complete with compression plates for all applications.

The upper compression plate of the 3-lug spring compressor is provided with a safety catch to prevent in- correct use of the compressor. To compress the spring, the 3 lugs on the compressor must be engaged in the compression plate, otherwise the compressor will slip out of the compression plate.

Note:
Existing 2-lug compression plates compression plates cannot be used with the 3-lug compressor.

B. Markings for Correct Engagement of 2-Lug Spring Compressor

When using the previous 2-lug spring compressor which does not have a safety catch, correct engagement of the compressor into the upper compression plate must be assured.








To do so, the compressor must be turned in the compression plate by 9O~. The milled red color marks must coincide (arrows, Figures 2 and 3).

When using the spring compressor with the springs installed in the vehicle, the red marks are easily visible from below.

Note:
To assure proper use for safety reasons, spring compressors which do not have the marks must be identified by grinding a groove into the respective components and highlighting them with red paint (Figures 2 and 3).

C. Use of 2-Lug Spring Compressor on 4MATIC Vehicles

To use the 2-lug spring compressor on 4MATIC vehicles, special compression plates are required. These plates are available separately under part no. 124 589 18 63 00.

D. WARNING!

Use extreme caution when working with spring compressors. The proper use may result in personal injury. Therefore, inspect all components for damage before using than. Never use an impact wrench for tensioning or slackening the pressor. This could damage the threads, allowing the compressor to fly apart and possibly result in personal injury.
