6. Using a clean lint free cloth, apply Sika Aktiva-
tor to the black ceramic Frit surrounding the
new window. Use a clean cloth and wipe off
Sika Aktivator. Allow ten minutes to dry.
7. For the side windows, be sure to utilize a total
of six or seven (SM2897) glass installation
bumpers to the cab, equally spaced around the
previously marked glass perimeter, approxi-
mately 0.75 in (19 mm) inboard from where the
edge of the glass will be when installed.
NOTE: Be careful not to place adhesive too far
inboard, as it will make any future replacement more
difficult.
8. Apply a continuous even bead of the adhesive
approximately 0.38 in. (10 mm) in diameter to
the cab skin at a distance 0.50 - 0.63 in. (13 - 16
mm) inboard from the previously marked final
location of the glass edges from Step 4.
9. Immediately install glass to the vehicle. Care-
fully locate the glass in place with the black
masking side towards the adhesive. Carefully
press firmly, but not abruptly, into place assur-
ing that the glass is properly seated. DO NOT
POUND THE GLASS INTO PLACE.
10. Using a wooden prop and furnace/duct tape,
hold the glass in place for at least two (2) full
hours (or double the adhesive manufacturer's
curing time, which ever time is longer).

NOTE: Do not allow the truck to move until double
the cure time for the adhesive has passed.
Otherwise, vibration or movement from a moving
truck will weaken the adhesive bond and the glass
may fall off the cab.
Be certain to follow all the adhesive manufac-
turer's instructions for use, including full allow-
ances for proper curing time. The curing time
may be as long as 48 hours (24 hours for some
adhesives, then double it) before a truck can be
driven.
11. Remove tape or prop from glass after the cure
time has expired.
