INSTALLATION—SHORT METHOD
WARNING: REVIEW ALL WARNINGS AND CAU-
TIONS IN THIS GROUP BEFORE PRECEDING WITH
INSTALLATION.
(1) Trim the urethane from the pinchweld flanges.
Leave a 3 mm (0.1 in.) level base of urethane on the
pinchweld flanges.
WARNING: DO NOT USE SOLVENT BASED GLASS
CLEANER TO CLEAN
APPLYING GLASS PREP AND PRIMER. POOR
ADHESION CAN RESULT.
(2) Clean inside of windshield with ammonia based
glass cleaner and lint-free cloth.
(3) Prime outer perimeter of interior side of glass
16 mm (5/8 inch) from edge. Use a wipe-off type ure-
thane primer and wipe glass dry after primer appli-
cation.
NOTE: The reveal molding has an adhesive applied
to the windshield contact surface to help secure the
molding to the windshield during the installation
procedure.
WINDSHIELD BEFORE
(4) Apply the molding to the windshield:
• With the molding at room temperature, press
the molding onto the windshield corners.
• From corner to corner, work the molding to the
center of each side. (Some stretching of the molding
may be required during this procedure.)
(5) Place the glass on the pinchweld flanges and
inspect for gaps in the urethane. Gaps in excess of 3
mm (1/8 inch) must be filled with urethane.
(6) Adjust windshield glass position until it is
aligned with the flanges and adhesive.
(7) Using a grease pencil or equivalent, make
alignment marks on the glass and body.
(8) Remove replacement windshield from wind-
shield opening.
(9) Position the windshield inside up on a suitable
work surface with two padded, wood 10 cm by 10 cm
by 50 cm (4 in. by 4 in. by 20 in.) blocks, placed par-
allel 75 cm (2.5 ft.) apart (Fig. 2).
CAUTION: Avoid spilling or dripping primer on
painted surfaces. Clean spills or drips immediately.
The primer will damage the paint if it remains on
the surface for any length of time.
(10) If the replacement windshield glass does not
have blackout primer:
• Attach a 25 mm (1 in) wide masking tape band
around the interior side of the glass 16 mm (5/8 in)
from the edge of the glass (Fig. 3).
• Do not attach tape along the bottom of the glass
and attach it only to the inside of the glass.
• Clean the 16-mm (5/8-in) wide surface area
around the glass with isopropyl alcohol.
• Thoroughly mix and apply glass blackout primer
to the 16 mm (5/8 in) surface area around the inte-
rior side of the glass (Fig. 4).
• Allow the primer to dry for at least 10-12 min-
utes.
(11) Apply a small amount of adhesive to the bot-
tom support spacers and attach the support spacers
to the bottom of the windshield, 170 mm inboard
from the outer windshield edge (Fig. 5).
(12) Cut the urethane adhesive applicator nozzle
(Fig. 6).
CAUTION: Be prepared to install the glass immedi-
ately after applying the adhesive, as the adhesive
will begin to cure in less than 10 minutes.
(13) Apply a continuous, 6-mm (1/4-in) diameter
bead of urethane adhesive to the surface area.
(14) Align the glass with the reference marks and
position the glass on the pinchweld flanges. Ensure
that the windshield glass is correctly seated on the
support spacers.
