Suspension Spring ( Coil / Leaf ): Application and ID
Test values of springsGeneral information about springs
Manufactured springs are subject to tolerances. To provide uniform installation conditions on vehicle, the tolerances showing up during production of the springs are compensated with regard to spring length or installation height. To identify the various spring lengths, the springs are marked with paint at the final, lower end of coil. (Color marks in center of spring are inspection marks of manufacturer, they are of no significance with regard to length of spring). The part number and the DB company symbol are punched into each spring at end of final coil.
a) Front springs
On front springs the different spring lengths (installation heights) are identified by the following colors:
Model 107 114 115:
Red = short spring
Blue = long spring
The various installation heights of the springs and the different axle loads resulting for the individual vehicle models and versions are compensated by the installation of rubber mounts of varying height (refer to Adjustment of front springs).
b) Rear springs
Model 107 114115
The color code on rear springs is the same as on front springs, therefore:
Red = short spring
Blue = long spring
The various installation heights and rear axle loads are compensated by rubber mounts of varying height for the rear springs (refer to Adjustment of rear springs).
