Inspection of Parts
Reuse Guideline for the Flexible
Exhaust Pipe
This Information Element will address the following
applications for the lines group - flex pipe: the
installation, the handling and the reusability. The lines
group - flex pipe is defined as the connection
between the turbocharger diffuser outlet and the
Clean Emissions Module (CEM) inlet.
Removal of the Lines Group
Removal Procedure
The ends of the bellows are very sharp. Injury
could occur if the bellows are not handled
properly. Handle the bellows by the convolutions.
NOTICE
The alignment of the bellows is important. Improper
alignment may lead to premature failure of the bel-
lows. Misalignment can be identified by visually in-
specting the uniformity of the spacing between the
convolutions.
Inspect the bellows for damage prior to installation. If
there is any damage to the convolutions, discard the
bellows. If there is any difficulty in installation after
the repair, discard the bellows.
The alignment of the bellows is important. Improper
lateral alignment is two sealing surfaces that do not
align with each other. The proper lateral adjustment
is shown in Illustration 1 .
Proper alignment means that initial alignment of all
components that are held together by the
components referenced in Illustration 1 are
maintained.
Note: Do not force the bellows into the position.
Note: Failure to reinstall the bellows into the as
removed alignment will result in a failure of the part
and a needed replacement.

Typical example
(1) Alignment marks
(2) Ball clamp
(3) Tube
(4) Slip joint clamp
(5) Bellows
(6) Ball clamp
1. Draw alignment marks that will cover both the lines
group and the associated clamps. Refer to
Illustration 1 .
Illustration 2 g02239794
Typical example
Bellows with protective covering installed
2. Wrap the bellows with a protective cover to avoid
possible damage to the bellows during the
removal and installation.
3. Loosen clamp assemblies (2), and (6).
4. Remove the lines group.
Note: Removal of the entire line group as a whole is
ideal. However, in some applications the assembly
must be disassembled further in order for the
assembly to be removed.
