Tension the Clamp on the Air Spring.

- Before tensioning the clamp pay attention to their installation position. Refer to → Fig. "Air Line Bracket Installation Position" and → Fig. "Clamp Installation Position".

- To tension the lower clamp press the front wheels accordingly.

- To tension the upper clamp lift the wheel bearing into the standard vehicle height. Refer to → Chapter "Wheel Bearing at Standard Vehicle Height, Lifting Vehicles with Air Suspension".

- Attach the Clampling Pliers -VAG1682A- as shown. When doing that, make sure the jaws on the pliers are centered -arrow- on the clamping sleeve -2-.

  Note

  • Make sure the threads on the spindle on the pliers move easily. Lubricate with MoS2 grease, if necessary.
  • If difficult to tighten, for example because of dirty threads, the proper clamping force of the clamping sleeve will not be reached even when tightened to the specification.

- Tension the clamp by turning the spindle -1- with the torque wrench, at the same time do not tilt the pliers.
