Method B
• Using a drill equipped with the special sharp
pointed rod, drill through the window seal
into one of the bottom corners, from a 30º
angle with reference to the vehicle.
• This procedure requires accuracy and it is
possible not to succeed on the first attempt.
From the inside of vehicle, a second person
ensures the rod passes through.
• Remove the rod, thread the wire into the
small hole. Reinsert the rod and the wire
into the hole far enough so that the person
inside the vehicle can pull the rod using a
pair of pliers.
• Attach the wire ends to the specially
designed handles.
• Pull in turn from the inside and the outside
of vehicle to gradually cut the Sika bead on
the window perimeter.
• When you reach top corner, detach wire
from the outside handle, secure it to a fish
wire or rod and thread it underneath the
aluminum molding behind the rivets.
• Detach wire from fish wire and continue
cutting using the handle.
• Cut Sika bead until you come back to
starting point, then you can remove the
window by carefully pushing it out from the
inside of vehicle.
8.1.2 Preparation of Structure and Installation
of Window
Preparation of Structure
• Remove old Sika adhesive.
• If primer was removed at the same time
than Sika, perform the following steps:
o Clean using anti-silicone.
o Remove from structure old primer using
a sander (120-150 grit).
o Clean again using anti-silicone.
o Apply 206 G+P primer.
• Reactivate 206 G+P primer.
Installation of Window
• Use window cleaner around window interior
perimeter and edges to remove any oily film
while inspecting for damages.
• Apply Sika Aktivator.
• Using a triangular nozzle (20mm X 10mm),
apply Sika Ultrafast II onto structure.
NOTE
You only have 8 minutes to install window
once the SIKA ULTRAFAST II product is
applied.
• Install window.
CAUTION
To prevent damaging the Sika joint, do not
raise the window once it as touched the bead.
• Before compressing window against Sika
joint, install two stops into the aluminum
extrusion one inch from each window edge.
• Verify window alignment with reference to
adjacent surfaces.
• Vehicle must remain stationary for 30
minutes at more than 23°C.
8.2 EMERGENCY EXIT WINDOWS
Three of the windows on curb side of the X3-45
serve as emergency exits, while there are four
on driver’s side. See figure 33. Except for the
top window side, the three other glass sides are
unprotected, which causes the workers to be
exceptionally careful when manipulating or
installing such windows.
In addition, when it becomes necessary to lay
down the unprotected edges of the glass
window, never use a steel or concrete floor
support. It is recommended to use a wooden
support, even better, a padded surface.
