Rubber CV Boot, Venting

The CV boot is frequently pressed in when placed on the CV joint body. This creates a vacuum in the CV boot, which pulls a fold inward when the car is driven -arrow-.

Therefore, note the following:

- Before clamping the clamping sleeves, balance the pressure by raising the CV boot.

- Tighten the Clamping Pliers -VAG1682A- by turning spindle -A- using a torque wrench (do not tilt the Clamping Pliers -VAG1682A-).

  • Tightening specification: 20 Nm

  Note

  • Make sure the threads on the spindle on the pliers move easily. Lubricate with MoS2 grease, if necessary.
  • If the thread is tight, for example it is dirty, the required tensioning force for the hose clamp will not be achieved in spite of correct torque specification settings.
