– Coat sealing surface of cover with -D 454 300 A2- .
– Apply continuous bead of sealant with ∅ 2...3 mm past inner
edge of holes -arrow- to clean surface of cover.

ment is possible once the part has been hammered on.

Tighten clamp on outer joint

sure jaws of tensioner lie in corners -arrows B- of ear on O-
type clip.
– Tighten clamp by turning spindle with a torque wrench (do not
cant pliers).
Note
Due to the hard material of the protective boot (compared to
♦
rubber) and the necessity of using a stainless steel clamp, it
is only possible to tension the clamp with clamp tensioner -
V.A.G 1682- .
Specified torque: 25 Nm.
♦
Use torque wrench -C- with setting range 5 ... 50 Nm (e.g.
♦
torque wrench - V.A.G 1331- ).
Ensure that the spindle thread -A- moves smoothly. Apply
♦
MOS 2 grease if necessary.
♦ If the spindle is tight owing to the thread being dirty, for exam‐
ple, the force required to tighten the clip will not be attained in
spite of correct specified torque specification.
