10. Using a caulking gun, apply an even layer of Sikaflex? 295 - UV, (polyurethane windscreen adhesive) all around of the window as close as possible to its edge. Refer to Image1.10.1.
Dimensions for the width and the height of the adhesive are 10 - 15mm (0.39 to 0.59 inch) (width) and 10mm (0.39 inch) (depth).
Depending on work environment, operator could prefer either to glue the polycarbonate window (Refer to Image1.11.1) or the cab frame (Refer to Image1.11.2)
Cutting a groove into the tip of the cartridge will help in the even application of the Sikaflex? 295 - UV. Refer to Image1.11.3.
11. To avoid window moving and ensure 5mm clearance between the edge of the window and the edge of the frame, install three 178-5574 Spacers on cab metallic frame as shown in Image1.12.1.
To insure proper glue thickness after glass application, locate five self-adhesive 5J-5003 Plugs (Bumpers) at the locations shown in Image1.13.1.
Note: The bumpers should be located as close as possible to the glue as illustrated in Step 10.
12. Install two suction cup holders on the internal and two on the external side of the window in order to hold it during installation operations. The first operator handles the window, while the second takes place into the cab. Refer to Image1.14.1.
13. Put pressure onto the polycarbonate window and hold in place for 10 minutes. You can use suction cup holders to do so. Ensure that the even gap all around between the edge of the window and the edge of the frame is maintained (Read Step 10). Refer to Image1.15.1.
After complete installation of the polycarbonate window, thickness of the adhesive must be 5mm thick. Failure to do so could conduct in glass unstucking after thermal expansion. Refer to Image1.15.2.
14. Remove eventual excess of Sikaflex? 295 - UV using appropriate method, for example, a folded sheet of cardboard can be used to facilitate this operation. Refer to Image1.16.1.
15. Wet stains or residues of Sikaflex? 295 - UV can be removed using Sika? Remover 208. Refer to Image1.17.1. Once Sikaflex? 295 - UV is dry, it can only be removed using a manual tool like a cutout knife. Cleaning of the hands and skin has to be carried out immediately using an adapted soap. Do not use solvents.
16. Sikaflex? 256 will cure in 12 to 24 hours. Do not expose the cab to temperature below 10?C during 24 hours for proper adhesive curing. Do not slam the cab door for 24 hours. The excessive air pressure in the cab from slamming the door may loosen the window. It is strongly recommended to NOT MOVE or OPERATE the machine during the 24 hours following this Rework Procedure. Failure to do so will eventually cause the window seal to leak.
Note: Apply tape to keep the window secured in the opening for a minimum of four hours.
