-- Position : VAG1682A as shown in illustration. When doing this, make sure that edges of clamping pliers are seated in corners -arrows B- of clamp.

-- Tighten the hose clamp by turning spindle -A- using a torque wrench (do not tilt clamping pliers).

Tightening specification: 25 Nm.

NOTE:

A stainless steel clamp must be used due to hardness of CV boot material (compared to rubber). This clamp can only be tensioned using : VAG1682A .

Be sure clamp tool spindle thread -A- moves freely. Grease with MoS₂ grease if necessary.

If the thread is tight for example, dirty, the required tensioning force for the hose clamp will not be achieved in spite of correct torque specification settings.
