During the work of welding, drilling, grinding, cutting near
brake system piping, especially if this is made of plastic, and
electric cables, take the appropriate precautions to protect
them, contemplating their removal if required. All the parts
of the chassis frame subject to reconditioning will need to be
protected against oxidation and corrosion.
This protection and painting will need to be done carefully
on all the parts concerned, as per any relevant instructions,
methods and precautions of the paint manufacturers.
The chassis frame is reconditioned by wedge heating the
relevant part with a blowpipe.
During this operation the metal needs to turn cherry red,
which corresponds to a temperature of 600 - 680
°C.
The heated points must undergo no further heating.
Let the treated parts cool slowly without using any water,
compressed air or the like.
Straighten the side bend of the chassis frame with wedge
heating on the top and bottom waist of the part concerning
the chassis frame.
The tip of the heating wedge has to lie in the direction of the
required bend.
If the base of the two heating wedges is in the top plate of
the structural member, then the plate also needs to be
heated, but last.
Straighten the sag in the chassis frame downwards or
upwards with wedge heating on the top plate of the
structural member. In the case of downward bending, the
base (a) of the heating wedge is at the bottom. In the case
of upward bending, do the opposite.
The relevant bottom or top waist of the structural member
has to be heated last in the area of the base of the heating
wedge.
