each side on X3-45. They are made of fixed,
single or double-glazed, heat absorbing AS-3
glass. Windows are mounted in painted
aluminum extrusions, which hold the glass in
place from the top rail of the coach. The
extrusion also serves as a hinge to allow the
window to swing open when needed. The single-
glazed windows are made of tinted tempered
safety glass, while the double-glazed windows
are made of tinted tempered safety glass
outside and clear tempered glass inside.
For fixed side window removal or installation,
you will need:
Hammer or;
Drill equipped with a sharp pointed rod into
which a small hole was drilled;
Braided windshield wire and a pair of handles;
Gloves, goggles or face shield.

Fixed Window Removal
Method A

Apply a sticky plastic film onto window
outside surface (thermos) and break win-
dow. For single pane, apply a sticky plas-
tic film on both sides of window.
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.
