Fig. 1 Tightening clamp on air spring damper
^
Apply CV joint boot clamp tool V.A.G 1682 as shown. Make sure that the jaws of the CV joint boot clamp tool installed centered -arrow A- on the
clamp.
^
Tighten hose clamp by turning spindle with a torque wrench (take care to keep pliers straight).
Note:
^
Tightening torque: 8 Nm
^
Use torque wrench with an adjustment range of 4 - 20 Nm (e.g. V.A.G 1410).
^
Make sure that the thread of the CV joint boot clamp tool spindle -A- is not stiff. Lubricate with MoS2 grease, if necessary.
^
If the thread is tight e.g. due to dirt, the required tightening force for the clamp will not be achieved in spite of correct tightening torque
settings.
