Mount and Tension Stainless Steel Clamp using the Clamping Pliers -VAG1682A- as Illustrated

- Attach the CV Joint Boot Clamp Tool -VAG1682- as illustrated. When doing this, make sure that edges of clamping pliers are seated in corners -arrows B- of clamp.

- Tension clamp by turning spindle with a torque wrench (do not tilt clamp tool).

  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 Clamping Pliers -VAG1682A-.
  • Tightening specification: 25 Nm.
  • Use torque wrench -C- with adjustment range 5...50 Nm (for example Torque Wrench 1331 5-50Nm -VAG1331-).
  • Make sure the threads on the spindle -A- on the pliers move easily. Lubricate with MOS 2 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.
