REPLACEMENT
This operation shall be performed only on the repair bench. For the specific supports mount-
ing on the bench, please see the 40 sub-chapter.
DISMOUNTING
In order to reduce the distortion risk of
the front longitudinal girder, for the welding
points detaching it is recommended the use
of steel cutter. Dismount the damaged elements, which
are in contact with the front longitudinal girder.
Pr oceed to a straightening on the body
checking/straightening Celette type, until
bringing it, as closed as possible to the initial
shape.
Detach the welding points of the front longitudinal girder which are in connection with : - the front cross bar in t he a rea (1);
- the front wing lining in the area (2);
- the central floor in the area (3);
- the c entral cross bar in the a rea (4);
- the upper longitudinal girder closing plate in the area (5).
Detach the welding points of the cross bar with the floor closing plate and the central floor in
the are a (6). Remove the damaged element.
Straighten the areas resulted by dismounting.
Grind the areas resulted by dismounting.
REMOUNTING
Position and center the new element.
Perform an electric welding (by spots and under gas protection) as follows: - in the area (1) connecting the front longitudinal girder with the front cross bar;
- in the area (2) connecting the front longitudinal girder with the front wing lining;
- in the area (3) connecting the front longitudinal girder with the central floor;
- in the area (4) connecting the front longitudinal girder with the front cross bar;
- in the area (5) connecting the front longitudinal girder with the upper girder closing plate;
- in the area (6) connecting the front longitudinal girder with the cowl panel.
Protect the new element with a corrosion preventing and noise absorbent product.
