Control dimension front lower edge of vibration damper to lower edge of actuator
- Lower spring plate must not be fitted!
- Pressure line connection must be flush with the vibration damper position plate > Position of actuator.
- Press on the actuator until the control dimension -s- of 148.6 mm +/- 1 mm is reached.
Information

Do not fit the stop cap at an angle!

Positioning the lower spring plate
- Position lower spring plate so that the end of the coil spring is positioned clockwise at an angle -X- to the pressure line.
- Align lower spring contact bracket with the pressure line (front axle lift system) at an angle of 45°.

For vehicles with front axle lift system: Press actuator -2- onto the vibration damper -1- .

Information

Explanation of the colored dots on the coil spring:

Colored dots -1- provide information about the allocation to the vehicle variant and equipment (see Porsche Spare Parts Information).
Colored dot -2- indicates the tolerance group to determine whether a tolerance compensation shim must be fitted.
Colored dot -2- yellow : no tolerance compensation shim should be installed.

NOTE: If the tolerance is borderline, a tolerance compensation shim can still be installed during production. Do not install a tolerance compensation shim when installing a replacement spring with a yellow dot!

Colored dot -2- blue : a tolerance compensation shim can be installed on the production side or not!

Only when installing a replacement spring with a blue colored dot, also install a to trance compensation shim!

WARNING:
Preloaded or pressurized components
- Risk of squashing or bruising
  → Do not reach into the danger area.
  
  → Relieve tension on components before starting work.
  
  → Secure components to prevent them from loosening suddenly.
Pre-tension the spring strut until the tension on the piston rod is relieved.
Tighten hexagon nut -1- using a commercially available open socket-wrench insert (af 21 mm) for example Hazet, number 2593.
Counter at the hexagon nut -2- on the piston rod.

> Tightening torque 70 Nm (52 ftlb.)
Seal hexagon nut -1- and projecting part of the piston rod -2- with Pfinder AP14/4 corrosion protection wax.
