    Important: Keep the cutting edge of the tool against the window. This separates the urethane adhesive from the window.

  8. Use the J 24402-A and the J 39032 in order to remove the window.
  9. With the aid of an assistant, remove the window.
  10. The following components may reveal the causes of a broken window:
  11. • The flange of the window opening
    • The window reveal molding
    • The window
  12. Look for any of the following conditions in order to prevent damage to the window:
  13. • A high weld
    • Solder spots
    • Hardened spot weld sealer
    • Any obstruction or irregularity in the pinchweld flange
  14. Inspect the condition of the window opening and the adhesive bead in order to determine which installation method you will use. Refer to Short Method Description or Extended Method Description .
  15. Important: If corrosion of the pinchweld flange is present, or if sheet metal repairs or replacements are necessary, refinish the pinchweld flange in order to present a clean primer only surface. If repairs to the paint are required, mask the flange bonding area prior to the application of the color coat in order to provide a clean primer only surface. Use material such as BASF DE17®, DuPont 2610®, and PPG DP40®.

  16. Shake well the pinchweld primer (#3 black).

  17. Object Number: 245283  Size: SH
  18. Use a new dauber in order to apply the primer to the primed surface on the flange in the bonding area (1).
  19. Allow approximately 10 minutes for drying the primer.

Installation Procedure

  1. With the aid of an assistant, dry fit the window in the opening in order to determine the correct position.

  2. Object Number: 245249  Size: SH
  3. Use masking tape in order to mark the location of the window (1) in the opening.
  4. Slit the masking tape at the top edge of the window.
  5. Remove the window.
  6. Place the window on a clean, protected surface.

    8.1. Remove all but a thin film of the existing bead of adhesive from the pinchweld flange.
    8.2. Shake well the pinchweld primer (#3 black).
    8.3. Use a new dauber in order to apply the primer to exposed painted surfaces or scratches in the flange in the bonding area.
    8.4. Allow approximately 10 minutes for drying the primer.

    Important: Use care when applying the window prep (#1 clear) in order to prevent the window prep from running into the vision area of the window. This primer dries almost instantly. This primer may stain the view area of the window.

  13. Using a new dauber, apply window prep (#1 clear) to an area approximately 10-16 mm (3/8-5/8 in) around the entire perimeter of the glass inner surface.
  14. Apply window prep (#1 clear) to any exposed edges of the window.
  15. Immediately wipe the primed area with a clean cloth.

  21. Prior to application of the urethane adhesive, cut the tip of the applicator nozzle in order to provide the following bead sizes:
  22. • For the short method, cut the tip in order to provide an adhesive bead of approximately 4.5 mm (1/8-3/16 in).
    • For the extended method, cut the tip in order to provide an adhesive bead of approximately 14 mm (9/16 in).

    Object Number: 161429  Size: SH
