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.
- Tightening specification: 8 Nm.
