REPLACING WINDSCREEN WINDOW
General
New EuroCargo Tector windscreen windows observe the
industrial standard which concerns fixed (glued) window
fastening.
This is a great advantage, both in quality, because it assures
perfect impermeableness and resistance to water, and in
safety, because it makes structure more integral and lighter.
To detach the windscreen window, it can be operated with
either a vibration cutter provided with a suitable cutting blade
or harmonic wire.
!
Do not use lubricants while cutting.
Blades must be always sharp.

Figure 41
A vibration cutter is made up of special shears and a suitable
set of vibrating blades with a number of oscillations electrically
adjustable.
It can be used to cut polyurethane sealants.
It is important that, while cutting, the blade goes on parallel
both to the window and body, in order to prevent the blade
from breaking.
In order to prevent the shears from overheating, it is useful to
adjust both advance and number of oscillations depending on
use conditions.
In detail (A) it is shown the scraper to be applied to vibration
shears to level sealant residue.

For cutting the sealant bead with the harmonic wire, it is
necessary to use a tool as illustrated in Figure 44.

!
Before starting the cutting procedure, it is needed to
protect, though an adhesive tape, the painted area, in
order to avoid possible damages.

Figure 44
Cut a wire section about 500 mm long and, using a check tool
(3), put in a wire end (1) through sealant bead (2), starting
from windscreen window lower centre (see Figure 45).
Fix the wire end to check tool (3), operating inside the vehicle,
and the other end to the draw handle outside the vehicle.
The inside operator has to point the check tool at sealant bead
(2), about 300 mm from where wire (1) runs through.
Figure 45
78708
The other operator, who is outside the vehicle, has to pull the
draw handle (1) while following the windscreen profile, and
cut the sealant bead.
Repeat the operation for 300 mm sections throughout the
profile, properly decreasing their length along the corners of
the window, until a sealant bead complete cut is achieved,
then remove the window using the vacuum cups.
Preparing the windscreen opening
Figure 46
78709
By using a suitable blade, cut and level the windscreen opening
sealant so as to leave 0.25 to 1 mm thickness in order not to
scratch paint.
Remove sealant residue through compressed air, then
degrease thoroughly with heptane and expendable paper.
The sealant film left on the windscreen opening will
serve as a support for next gluing.
!
Removal (with harmonic wire)
Before performing windscreen detaching operation, it is
needed to remove, from the vehicle, those components which
would hinder operations or could suffer damage while
executing these operations.

In case of recovery of the original window detached:
- by using a suitable blade, cut and level the sealant bead
trying to reduce thickness as much as possible. It is not
necessary to take off the sealant thoroughly. Avoid to
touch the surface of residual sealant. Pay attention not to
damage the black silk screen on window perimeter.

Wait 15 minutes before going on with operations, so as to
let the adhesion promoter solvent evaporate.
Refitting
!
In case of recovery of the windscreen window, it is not
needed to apply the adhesion promoter on sealant
left.

Put in windscreen window (4) upper seal (6). Position plugs
against horizontal sinking (5) on the windscreen window
opening. Position pads against vertical (3) and horizontal (2)
sinking. Make a test assembling and perfectly center the
windscreen window. Once windscreen window centering has
been completed, mark windscreen and seat mutual position
with adhesive tape strips (1). Cut the adhesive tape strips and
remove the windscreen.
