Removing Coil Spring

Information 

• Coil springs must not be pressed together as far as the block. 
• The surface of the coil spring must not be damaged (danger of corrosion). 
• Never use solvents to clean the coil springs. 

Information 

The spreader device VAS 6907/8/VAS 6274/12-4  makes it easier to remove and install coil springs.

When the spreader device is used, it prevents the axle from moving upwards when tensioning the coil spring.

1. Insert spreader device VAS 6907/8/VAS 6274/12-4 -1-  from the tool sets specified above.

   Twist lock

   1. 5.1 Turn both pressure plates -1 and 2-  as far as required in the coil spring so that there are at least 3 windings between them.
   2. 5.2 Screw twist locks of both pressure plates -1 and 2-  together.
6. Tension coil spring -1-  .

   Tools on coil spring

   1. 6.1 Spindle VAS 6907/3 -2-  must always be greased at the front before use with a thin coating of the grease that comes with the > VAS 6907 - spring tensioning system  .
   2. 6.2 Screw the spindle VAS 6907/3 -2-  using socket wrench VAS 6907/5 -4-  into the piston VAS 6907/4/VAS 6274/12-6 or 12-7 -3-. 
   3. 6.3 Counter using VAS 6907/7  holding wrench.
   4. 6.4 Pre-tension pressure plates slightly using spindle VAS 6907/3 -2-  and check that the coil spring is fitted correctly -1-  in the pressure plates.
7. Remove coil spring -1-  .

   Coil spring

   1. 7.1 Tension coil spring -1-  using socket wrench VAS 6907/5  until the stone guard and upper and lower spring plates can be removed.
   2. 7.2 Guide out coil spring -1-  by pulling it forward at an angle at the bottom -Arrow-  .
   3. 7.3 Turn the spindle VAS 6907/3  back slightly if necessary so that it ends flush with the end of the coil spring -1-  . Never unscrew the spindle VAS 6907/3  fully.
8. Insert pre-tensioned coil spring -1-  into hydraulic tensioning device VAS 6907/9 -2-.

   Hydraulic clamping device

   1. 8.1 Insert coil spring -1-  into the hydraulic tensioning device VAS 6907/9 -2-  .
   2. 8.2 Fit lower end of spring in the spring compressing system at the relevant marking.

      L:  left coil spring

      R:  right coil spring

9. Relieve tension on coil spring in hydraulic tensioning device VAS 6907/9  .
   1. 9.1 Hydraulic tensioning device VAS 6907/9  must be tensioned using the > VAS 6179 - foot pump  until the tension on the pressure plates is relieved.
   2. 9.2 Unscrew spindle VAS 6907/3  using socket wrench VAS 6907/5  .
   3. 9.3 Unscrew screws on twist locks and remove pressure plates.
   4. 9.4 Relieve tension on the coil spring again and remove it from hydraulic tensioning device VAS 6907/9  .
