aComponents of tool Car. 1504 :
- (1) : Mandrel mounting,
- (2) : Mandrels,
- (3) : Tightening bolt,
- (4) : Body,
- (5) : Anvils,
- (6) : Special nut,
- (7) : Nut,
- (8) : Studs,
- (9) : Thrust nut.
1 - Tool preparation
aSelect the mandrel, anvil and insert assembly adap-
ted to the crimping operation to be carried out.
aScrew the mandrel (2) into the mandrel mounting (1)
(left-hand thread).
aTighten the bolt (3) onto the body (4) until the stop
(left-hand thread).
aScrew the anvil (5) into the body (4) (left-hand
thread)
aFit the assembly (1) and (2) into the body of the tool.
aScrew the insert (left-hand thread) onto the pull rod.2 - Using the tool
aTurn the tightening bolt (3) using a 24 mm wrench
while holding the tool handle.
Note:
To fi t the special nut (6) , insert the mandrel (2)
through the nut to be crimped and tighten it onto
the thrust nut (9) .
WARNING
Each time a panel is stripped in the workshop
(e.g. when drilling), degrease and wipe the area
and then use a fine paintbrush to apply the fol-
lowing:
-a pre-treatment primer,
-a two-part pr imer,
-paint in the vehicle body colour.
WARNING
The operator should be able to feel when the
crimping is complete (more force required for
tightening).
The insert has been crimped correctly when
there is no rotational play. Carry out this check
before unscrewing the « pull rod - mandrel »
assembly.

GENERAL INFORMATION
Hollow section inserts: Precautions for the repair
40A
The expanding inserts ensure that the vehicle cavities
are sealed and soundproofed. They react to the tempe-
rature when the bodywork is immersed in the catapho-
retic bath at the factory. These conditions cannot be
reproduced on the bodywork.
As inserts are not recoverable, always replace expan-
ding inserts.
The inserts supplied by the Parts Department are
identical to the original parts.
To obtain the same sealing and soundproofing proper-
ties, carry out the following operations:
-clean the bonding surfaces with heptane,
-if necessary, block the holes in the insert using pieces
cut from a soundproofing pad.
-apply a bead of preformed trim sealing mastic around
and inside the insert holes,
-fit the insert by compressing the mastic.
In some cases, it is possible to replace the accessible
part of the insert only, which must be cut out of the re-
placement part.WARNING
Do not refit the part after compressing the bead.
When EGW welding, protect the inserts from spat-
ter and heat dispersion.
For example, use a heat shield.

For the earth stud fitting procedure, see MR 400.
WARNING
To avoid damaging the vehicles electric and electro-
nic components, the earths of any wiring harness
near the weld area must be disconnected.
Position the earth of the welding machine as closely
as possible to the weld area (see MR 400).

DESIGN OF THE STRUCTURAL COMPONENT
A special feature of this part is that it is welded to the
front side members.WARNING
The information contained in the following descri-
bes the general repair procedure for all vehicles
having the same design for this part.
Before reading this general information, check that
there are no special notes associated with this vehi-
cle. These special notes are specified if necessary
in other parts of the sub-section dealing with the
component.
Note:
For a detailed description of a particular connec-
tion, see MR 400, 40A, General Information.

FRONT LOWER STRUCTURE
Front side member: General description

I - DESIGN OF THE STRUCTURAL COMPONENT
This is a basic part; its only function is that of front side
member, front section.II - AREA TO BE CUT FOR PARTIAL
REPLACEMENT
Cut 1:
This line marks the place in which it is possible to make
a partial replacement.
This operation allows you to access the inside of the
hollow section of the structural element to straighten it.
In this case, the side member weld line must be stag-
gered from that of its closure panel.
III - ASSEMBLY METHOD FOR A PARTIAL
REPLACEMENT
Only the connections which are specific to the partial
replacement by cutting are indicated.
If there are other issues regarding access to mating fa-
ces, the various replacement options are described in
the basic instructions for structural bodywork repair
(see MR 400). IMPORTANT
Use a repair bench to ensure the positioning of the
points and the geometr y of the axle assemblies.
Note:
The information contained in the following descri-
bes the general repair procedure for all vehicles
having the same design for this part.
Before reading the following general information,
make sure that there are no special notes associa-
ted with the vehicle. These special notes are speci-
fied if necessary in other par ts of the sub-section
dealing with the component.
Note:
For a detailed description of a particular connec-
tion, see MR 400.

110549
Note:
For the partial replacement of parts constituting a
single structural component, it is essential to stag-
ger the welds of each of the components.
WARNING
If the mating faces of the parts to be welded are not
accessible, make EGW plug welds to replace the
original resistance welds (see MR 400).
