Installation position of coil spring

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.

Information 

Coil springs must be replaced only in pairs.

2. Pre-tension the coil spring in hydraulic tensioning device VAS 6907/9 -9-  .
   1. 2.1 Hydraulic tensioning device VAS 6907/9  as required using the > VAS 6179 - foot pump  until the pressure plates -1 and 2-  can be inserted with a gap of 3 windings between them.
   2. 2.2 Insert pressure plate with locking mechanism VAS 6907/1/VAS 6274/12-2 -1-  and pressure plate with pivot bearing VAS 6907/2/VAS 6274/12-1  -2- into the coil spring in such a way that three windings are enclosed.
   3. 2.3 Insert piston VAS 6907/4/VAS 6274/12-6 or 12-7  -4- into the pressure plate with latch -1-  . Use T-bar wrench VAS6907/6  as an aid if necessary.
   4. 2.4 Press locking lever in to secure the piston -4-  .
   5. 2.5 Insert spindle VAS 6907/3  -3-.
   6. 2.6 Screw twist locks of both pressure plates -1 and 2-  together.
   7. 2.7 Tension coil spring using socket wrench VAS6907/5  .
