GLUED FIXED THERMOS WINDOW PANE –
INSTALLATION/GLUING PROCEDURE

APPLICATION
Model

VIN

X3-45 COMMUTER

DESCRIPTION
Use this procedure to perform the replacement of glued fixed thermos window. This procedure
may also be used for the replacement of non-thermos fixed window as the installation method is
similar.

PRE-ASSEMBLED FIXED THERMOS WINDOW PANE
To ensure an easy installation when replacing a broken fixed thermos window, the
pre-assembled fixed thermos window p/n 290072 should be selected as replacement part. This
pre-assembled fixed thermos window comes with the upper aluminum extrusion already glued
on the window pane. The aluminum extrusion will assure perfect vertical positioning and support
the window pane during adhesive curing.

PROCEDURE
DANGER
Park vehicle safely, apply parking brake, stop engine. Prior to working on the vehicle, set the ignition
switch to the OFF position and trip the main circuit breakers equipped with a trip button. On Commuter
type vehicles, set the battery master switch (master cut-out) to the OFF position.
1. Inside the vehicle, remove the finishing trims around the window.
2. Remove the stopper blocks located at the top of the broken window if applicable (FIGURE 1). There
may be a stopper block on the R.H. side as well as L.H. side of the window. These stopper blocks are
found at the top of each emergency exit windows.
NOTE
In order to reinstall the stopper blocks at their original location, identify which stopper block goes on
R.H. side and which one goes on L.H. side. You may use a piece of masking tape and write down the
position on it.

CAUTION
Do not open an emergency window on which the stopper block has been removed. The
emergency window could unhook and fall down.

FIGURE 1: STOPPER BLOCK

3. Remove all debris of broken window if applicable.

MI16-12 / Page 4 / 12

4. Remove adhesive/sealant on the involved structural members using a putty knife. Read the note
below first:
NOTE
Good adherence of glue to surface. Remove excess of glue using a putty knife. It is acceptable
leave a thin layer of glue on the surface instead of breaking the surface of adherence with the blade. If
primed surface is slightly scratched: Accept as it is.
If glue or primer become unstuck. Remove glue locally and sand defective area

5. The vertical rubber seal found on the L.H. and R.H. side vertical members (FIGURE 2) should be left
in place if in good condition. Replace damaged vertical rubber seal if applicable.
Vertical rubber seal p/n: 293250 RUBBER SEAL1292±6.35mm LG

NOTE
Rubber seal is stick to the structural member with pre-applied double face adhesive tape

FIGURE 2

6. To avoid weak bonding, thoroughly clean the old adhesive layer on the structural member identified in
FIGURE 3 and FIGURE 4 with silicone remover p/n 682989 and clean Chix clothes. Wipe and dry
surfaces with clean blue clothes.

NOTE
For silicone remover (anti-silicone) application technique, refer to annexed SAV00001C SURFACE
PREPARATION PRODUCT GUIDE.

7. In preparation to adhesive application, clean the dark area on the inner side of the window pane using
glass cleaner (refer to FIGURE 5).

FIGURE 5

MI16-12 / Page 6 / 12

8. The adhesive must be applied in a triangular shaped bead of 20mm X 10mm (13/16 in X13/32 in) as
shown on FIGURE 6.
NOTE
For application technique, refer to annexed SAV00001A TRIANGULAR BEAD APPLICATION RULES.

Open time: 18 minutes.
Clamping time: 90 minutes.
Vehicle stop time (No driving with vehicle): 90 minutes.
Cleaning: clean spills with silicone remover.
Smoothing: use water or soapy water on a clean cloth.

adhesive bead centered between the vertical member edge and the rubber extrusion (FIGURE 7).

side vertical members (FIGURE 8).
NOTE
The two adhesive beads of the upper horizontal structural members are very important and must be
done carefully to prevent water infiltration. Make sure that they reach the previously done vertical
beads.

11. Apply a continuous triangular bead of adhesive on the lower horizontal member (FIGURE 9).
NOTE
Make sure that the adhesive bead reaches the vertical beads previously done.

12. Install the window on the structure. Ideally, you would use suction cups (FIGURE 11) to manipulate
the window. Using the aluminum extrusion already fixed to the window pane, hook the window to the
rail found on the vehicle upper horizontal member (FIGURE 12). Place the window centered between
the two adjacent windows before pressing the fixed window against structure. The gaps found on the
right side and the left side should be equal. Wipe adhesive in excess if adhesive is visible from the
outside.

FIGURE 11: HAND SUCTION CUP

CAUTION
Never raise a window once it has been pressed against the structure because the adhesive joint would
break.

MI16-12 / Page 10 / 12

FIGURE 12

13. Check window alignment (flatness) with adjacent windows or panels. Using a small ruler (to prevent
scratching, do not use metal ruler onto glass), make sure the window pane is flush with the windows
located on each side of it. Allow enough clamping time for adhesive curing.

 Clamping time: 90 minutes.

On FIGURE 13, a special jig equipped with suction
cups is used to clamp/hold the fixed window on
the structural members from inside.

FIGURE 13

14. Allow 60 minutes before performing this step. While the adhesive is curing, from the interior of the
bus, fill the gap between the thermos window and the surrounding structural members with sealant
Simson ISR 70-03 (fill the whole window perimeter to ensure water tightness). Remove sealant in
excess using putty knife/scraper. Smooth down (FIGURE 15) the joint with finger or using clean
clothes soaked with water or soapy water. Sealant bead must be fully filled, uniformly applied, flush
with the thermos surface. Clean sealant in excess using silicone remover.

Interior tolerance: A gap of 1/8” (3mm)
minimum should be met between thermos
window and structural members.

OPEN TIME: the time interval after application of the adhesive during which
successful bonding of substrates can occur.
