Model 140, 129, 170, 202, 208, 210
The color marks in the middle of the spring are the manufacturer's inspection marks. They are of no significance related to the spring length.

The various spring lengths and the various axle loads, resulting from the individual vehicle models and versions, are compensated for by the installation of spring rubber mounts of different height.
The part number and DC trademark are stamped on the last lower coil on each spring.

The allocation of spring/rubber mounts to the vehicle model can be determined with the aid of the parts microfilm.

Model 140, 129 and model 202 (to 12/95)
Spring length tolerances arise during manufacture of the springs. The springs are color coded on the second coil from the bottom to allow the different spring lengths to be identified:

Red = short spring
Blue = long spring

Model 170, 171, 203, 208, 209, 210, 211, 219, 230 and Model 202 (starting 01/96)
The springs installed in these models are not ground and attached at the top. Color coding is no longer required due to lower production tolerance.
