Insert Tooling (C) and attach Tooling (D). Make sure that you leave 2 mm (0.08 inch) to 3 mm (0.1 inch) (G) of the old seal (6) on the cab (7). Use Tooling (C) in order to cut the urethane adhesive. Pull Tooling (C) back and forth in order to cut the urethane.
Remove Tooling (D) and Tooling (C) after the urethane adhesive has been cut.
Attach Tooling (F) to the top glass and remove the top glass from the cab. Use Tooling (B) in order to level the remaining urethane adhesive on the cab. The urethane surface should be consistent.
Apply the appropriate primer and paint to any scratches that may have been caused by removing the top glass. This will prevent rust from starting. Rust will cause water leaks at the seals.Installation of the Top Glass
Use Tooling (A) to mask the transparent area of the glass. Slightly sand the black area of the glass with sandpaper for good adherence of the primer. Surfaces must be clean, dry and free from all traces of grease, oil and dust. Wipe the black area of the glass with 9U-6917 Adhesive Cleaner (2) and allow the adhesive cleaner to dry.
Shake the can of 323-3872 Adhesive (5) vigorously until you hear the rattle of the metal ball inside the can. Spray the adhesive onto a brush or a felt pad. Apply a thin coat of adhesive on the black painted area of the glass. Do not apply at temperatures below 10° C (50° F) or above 35° C (95° F).Note: Do not apply more than one coat of the adhesive. Care must be taken in order to ensure that one application of the adhesive thoroughly covers the black painted area of the top glass. Reseal the container immediately after use. Allow the adhesive to dry from 30 seconds to 30 minutes.
