-- When doing this, make sure that edges of clamping pliers are seated in corners -arrows B- of clamp.

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

• The hard material of the CV boot (compared to rubber) makes it necessary to use a stainless steel hose clamp. It is only possible to tighten the hose clamp with Clamping Pliers VAG1682A.
• Tightening specification: 20 Nm.
• Use torque wrench with 5 to 50 Nm range (for example, Torque Wrench 1331 5-50Nm VAG1331).
• Make sure the thread on the spindle -A- is easy to move. Lubricate 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.

Mount and tension the clamp with the retaining tabs using Pliers 3340 as illustrated.
